How Does Bio Fertilizer Making Machine Work?

A bio fertilizer making machine typically works in the following way:

1. Solid waste raw materials like cow dung, press mud, crop residues, green leaves, etc. are loaded into the solid waste mixing chamber of the machine where they are mixed together in the required proportions to achieve the desired nutrient composition in the bio fertilizer. Additional amendments are also added in this step if required.

2. The mixed raw materials are then fed into the aerobic fermentation chamber. An air blower is used to provide controlled aeration to this chamber for aerobic fermentation. Moisture sensors and controllers maintain the optimum moisture levels for the microbial activity.

3. Bacteria, fungi and other microorganisms present in the raw materials thrive in the fermentation chamber and start decomposing the organic matter. They convert the nutrients into microbial biomass and stabilize them in an available form for plant uptake. The fermentation process results in reduction of pathogens, development of beneficial microbes and pleasant earthy smell.

4. The fermented material is then transferred to the curing chamber where it rests for 7-15 days. Curing allows further decomposition, development of microbial consortia and maturity of the bio fertilizer. It results in formation of dark, crumbly and aromatic granules.

5. The cured bio fertilizer then passes through a rotary or vibratory screen (if provided) where it is screened into different particle sizes suitable for different applications like foliar spray, drip irrigation, deep placement, etc. Screening also helps in separation of any inert materials.

6. The screened bio fertilizer powder is then automatically fed into the filling chamber where it is packed into pre-sterilized bags, bottles or other containers and sealed properly before dispatch. Proper packing and sealing maintains the quality and ensures no loss during storage and transportation.

7. Testing of the produced bio fertilizers is done to check their microbial count, nutrient composition, maturity, contaminants, etc. especially before marketing the products. Testing is important to ensure they meet the required standards of quality and suitability.

8. The bio fertilizers are finally dispatched to retailers or directly applied in farms as per the recommendations to promote sustainable agriculture while conserving natural resources.

So in summary, the machine works by mixing different raw materials, aerobically fermenting them, maturing the fermented material and packing it as bio fertilizer after screening and testing. Controlled production conditions result in production of high-quality bio fertilizers beneficial for cultivation and environment. Precise control of aeration, moisture, temperature, particle size and sealing ensures product safety, maturity and efficiency.

Working Principle of Bio Fertilizer Making Machine

The working principle of a bio fertilizer making machine mainly revolves around controlled aerobic fermentation of organic wastes to produce nutrient-rich biofertilizers. Some key steps in the working principle are:

1. Mixing of organic wastes

Different organic wastes like farm yard manure, green leaves, press mud, food waste, etc. are mixed together in the required proportions to achieve the desired nutrient composition in the biofertilizer based on the requirements of target crops. Additional amendments are also added if required.

2. Providing controlled aeration

An air blower is used to provide oxygen for aerobic fermentation of the waste materials. The aeration is controlled using a frequency converter to maintain optimal oxygen levels for microbial activity. Proper aeration leads to fast fermentation and production of quality biofertilizers.

3. Maintaining optimum moisture

Moisture sensors and controllers are used to automatically maintain the moisture content at the ideal levels for microbial growth and fermentation. Proper moisture promotes fast decomposition of organic matter and development of beneficial microbes.

4. Accelerating fermentation

The controlled aeration and ideal moisture conditions facilitate rapid growth of aerobic microorganisms like bacteria, fungi, actinomycetes etc. present in the waste materials. These microbes secrete enzymes and decompose the organic matter, releasing nutrients in an available form.

5. Maturing the biofertilizer

The fermented material is then moved to a curing chamber where it rests for about 2 weeks. Maturation helps in further decomposition of nutrients, development of microbial consortia and stabilization of biofertilizer characteristics. It results in formation of dark, crumbly and earthy granules with pleasant smell.

6. Reducing pathogens and increasing safety

The fermentation process leads to reduction or elimination of pathogens, weed seeds and other undesirable components present in the raw wastes. Maturation further helps in stabilization of microbial composition, ensuring product safety, hygiene and suitability for application on edible crops.

7. Improving nutrient use efficiency

Precise control of aeration, moisture and temperature during fermentation allows optimal decomposition of organic matter, avoiding excess production of ammonia. Nutrients get stabilized in forms that are readily available for plant uptake, improving their efficiency of utilization. This reduces excess use of any single nutrient.

8. Packing for distribution

The mature biofertilizer is properly packed, sealed and labeled before distribution to retailers, farmers and customers. Proper packing maintains the quality, prevents contamination, ensures safety, and allows transportation over long distances without any loss.

This covers the working principle of bio fertilizer making machines in detail.

So in summary, bio fertilizer making machines offer good flexibility for customization to suit diverse and specialized requirements. Proper customization leads to production of high-quality biofertilizers at optimized costs which promote their large scale adoption.

Is Bio Fertilizer Making Machine Batch or Continuous?

Bio fertilizer making machines can work in either batch or continuous mode depending on their design and components. Some key points regarding batch vs continuous processing are:

Batch processing

• Raw materials are fed into the machine in batches and processed separately before the next batch is fed. The batches do not mix during processing.

• After feeding a batch, the machine has to be stopped, cleaned and readied for the next batch. This results in idle time between batches.

• Batches can be of uniform size for convenience but final mixing of biofertilizer occurs after processing all batches. Nutrient composition depends on maintaining same proportions across batches.

• Smaller machines with limited number of fermentation and curing chambers typically work in batch mode. Manual or semi-automatic machines also usually work in batch mode.

• Batch processing is suitable when frequent change in raw material type or proportion is required. It allows flexibility but reduces capacity.

Continuous processing

• Raw materials are fed into the machine continuously at a steady and controlled rate. The materials mix uniformly during continuous flow through the processing chambers.

• No stoppage is required between change of materials or their proportions. The machine can run continuously for long durations.

• Continuous aeration, moisture supply, temperature control and screening/packing allows uninterrupted processing leading to higher productivity.

• Larger machines with multiple fermentation chambers and curing chambers connected in series typically enable continuous processing. Fully automatic machines also commonly allow continuous running.

• Continuous processing is more suitable for high volume production of uniform biofertilizers using same set of raw materials and proportions. However, flexibility reduces due to continuous flow. Any change requires stopping, cleaning and calibrating the entire system.

• Hybrid systems with partially continuous and batch processing also exist where flexibility and high volume benefits can be achieved simultaneously. But, they tend to be more complex.

In summary, both batch and continuous processing have their own advantages and suitability. Batch processing offers flexibility while continuous processing enables high productivity. 

A suitable balance can be achieved through customized design and controls based on specific requirements. Proper selection of processing mode leads to optimized performance, quality, cost and adoption of bio fertilizer making machines.

How to Make Bio Fertilizer Making Machine Fertilizer?

Here are the main steps to make bio fertilizer in a bio fertilizer making machine:

1. Selection and preparation of raw materials

Select suitable organic waste materials like cow dung, green leaves, press mud, food waste, etc. based on the required nutrient composition and availability. Clean, chop and mix the raw materials in the desired proportions. Add amendments like molasses, vermicompost or biochar if required to modify the characteristics.

2. Feeding the raw materials

Feed the mixed raw materials into the solid waste mixing chamber or hopper of the machine at a controlled rate. Use conveyors and feeders to ensure uniform feeding.

3. Starting controlled aeration

Turn on the blower and control the air flow using a frequency converter or airflow regulator to maintain optimal oxygen levels for aerobic fermentation in the fermentation chamber. Typically 5-10% oxygen by volume is maintained.

4. Maintaining ideal moisture

Use moisture sensors, sprinklers or fogging systems to automatically maintain the moisture content in the fermentation chamber at 60-70% (wet basis) which is suitable for microbial activity.

5. Monitoring temperature

The temperature in the fermentation chamber should be maintained at 35-45°C for faster fermentation. Use temperature sensors and cooling systems if required to keep it in the ideal range.

6. Facilitating fermentation

Provide agitation or turning of materials in the fermentation chamber to ensure uniform mixing and contact of microbes with the organic matter. Fermentation continues for 8-15 days depending on the raw materials and process conditions.

7. Curing the biofertilizer

Transfer the fermented material to the curing chamber and continue aeration at lower rates. Curing continues for 7-15 days during which the biofertilizer granules develop proper maturity, hardness, nutrient concentration and microbial consortia.

8. Screening and packing

Screen the cured biofertilizer to appropriate particle sizes using rotary or vibratory screens depending on the requirements. Pack the screened biofertilizer in pre-sterilized bags, bottles or containers and seal properly before dispatch.

9. Testing (optional)

How to Produce Round Granules in Bio Fertilizer Making Machine?

To produce round granules in a bio fertilizer making machine, some additional steps need to be followed:

1. Selecting appropriate raw materials

Choose raw materials that bind together well and can form round granules easily such as farm yard manure, press mud and green leaves. Avoid very fine and powdery materials. Moisture content should be on the higher side, around 65-70% to enable binding.

2. Reducing fermentation time

Limit the fermentation time to 6-8 days maximum. Longer fermentation leads to breakdown of structures and formation of fine powder. Shorter fermentation allows preservation of shape and size of raw materials which eventually forms round granules.

3. Maintaining higher aeration

Provide aeration at a higher rate, around 15-20% oxygen by volume. Higher aeration prevents anaerobic conditions, limits smell development and allows faster fermentation to reduce total process time. But, do not exceed oxygen levels of 15% to avoid drying out of materials.

4. Applying binding agents (optional)

Add binding agents such as clay, starch, agricultural lime or cement powder at 5-10% by weight of raw materials. These agents help in binding the materials together during compression into round granules.

5. Compressing the material

Use a pellet press or briquette press to compress the fermented and cured material into round granules. Apply sufficient pressure, around 50-100 MPa, to form hard round granules that do not break easily. Softer granules can be made using lower pressures.

6. Drying the granules (optional)

If the granules are soft and crumbly, they can be dried in a hot air oven at 50-60°C for 8-12 hours. Drying hardens and strengthens the granules, making them suitable for storage, transportation and application. But drying reduces the microbial load, so it is done only when necessary.

7. Testing and packing

Test the granules for characteristics like hardness, moisture content, nutrient composition, etc. and pack them in bags or containers based on the results and requirements before dispatch. Proper testing and packing of granules ensures their suitability, safety and longevity.

Following these additional steps allows producing hard round granules of biofertilizers in the machine instead of regular powder. Round granules have slower release of nutrients, higher bulk density and longer shelf life compared to powder. They are more suitable for broadcasting, broadcasting and as a basal application before plantation.

Some key points to consider while batching and rationing raw materials for producing fertilizer particles are:

1. Nutrient requirements of target crops

Determine the nitrogen (N), phosphorus (P) and potassium (K) requirements of the crops for which the fertilizer will be used. The nutrient composition of raw materials and fertilizer should meet these requirements. So, batch and ration raw materials accordingly.

2. C:N ratio

Maintain a C:N ratio between 25:1 to 30:1 for fast and effective fermentation. C:N ratio depends on the carbon content of raw materials. So, calculate C:N ratios of available raw materials and batch them to achieve the desired ratio in the final fertilizer.

3. Moisture content

Select raw materials and determine proportions to achieve a moisture content of 60-70% in the final fertilizer. Moisture is important for microbial activity and fermentation. Proper moisture enables fast decomposition and development of beneficial microbes.

4. Available nutrient content

Calculate the available NPK content of the raw materials based on their nutrient composition. Determine the proportions required to achieve at least 2-3% N, 1-2% P2O5 and 1-2% K2O in the fertilizer. These levels indicate high nutrient concentration suitable as a fertilizer.

5. Bulk density

Consider the bulk density of raw materials and required fertilizer particle size while proportioning. Loosely bulked materials will produce fine powder while densely bulked materials will produce coarse granules. Adjust proportions to achieve the required particle size.

6. Microbial composition

Include raw materials rich in nitrogen fixing, phosphate solubilizing and potassium mobilizing microbes based on the requirements. Proportion them in a way that desired types of microbes dominate in the final fertilizer. This enhances nutrient use efficiency and fertility build up.

7. Carbon content

Raw materials high in carbon such as green leaves or lignite also improve carbon content in the fertilizer apart from nutrients. Carbon is essential for increasing organic carbon pools in soil, water retention and other benefits. Proportion carbohydrate-rich raw materials accordingly.

8. Amendment inclusion

Add amendments like molasses, biochar, vermicompost, etc. based on the requirements to modify characteristics of the fertilizer such as moisture retention, nutrient release pattern, microbial composition, etc. Use them in required proportions to achieve the desired specifications.

In summary, carefully determining the requirements, calculating properties of available raw materials and proportioning them rationally based on nutrients, moisture, carbon, microbial composition and other factors leads to production of high-quality fertilizer particles suitable for the intended use. Proper batching and rationing results in optimized utilization of resources and maximum benefits to soil, environment, crops and farmers.

How to Grind Fertilizer Granules to Powder?

Here are some steps to grind fertilizer granules into powder:

1. Choose a grinding machine

Select a grinding machine suitable for grinding granular fertilizers into powder based on the hardiness of granules, required powder fineness and batch size. Some options are hammer mill, ball mill, pin mill, rotary mill, etc. Harder granules require more heavy-duty grinders.

2. Set the required fineness

Determine the desired powder fineness in terms of mesh size or micron size. Finer powder will have higher surface area for faster release of nutrients. Choose a fineness suitable for the intended use such as foliar spray, broadcasting or deep placement.

3. Adjust the machine settings

Make adjustments to the machine settings such as grate opening size, number of hammers/balls, rpm of grinder, batch size, etc. to achieve the required fineness. Larger grate opening or lower rpm will produce coarser powder.

4. Add moisture (if required)

Add a small amount of water, around 3-5% by weight of granules, before grinding if the granules tend to fly away easily or are very dusty. Moisture prevents excessive loss of material during grinding and enables uniform grinding. But do not add too much moisture.

5. Grind the granules in batches

Feed the granules into the grinder in small batches to allow effective grinding of each batch and control over fineness. Overloading the grinder will reduce its efficiency. Grind each batch completely before feeding the next batch.

6. Collect the powder

Use a fine mesh collection bag or cyclone collector to collect the ground powder coming out of the grinder. This will allow collection of even the finest powder particles. Avoid loss of any powder.

7. Sieve the powder (optional)

Pass the collected powder through a fine mesh sieve based on the required fineness to remove any oversized particles if needed. Sieving will make the powder more uniform in size.

8. Moisten and pack

Add a little moisture (around 1-3%) to the powder if it seems very dusty before packing to avoid dustiness during handling and application. Pack the powder in pre-sterilized bags or containers. Sealed packing maintains quality during storage.

9. Test and label

Test the powder for characteristics like moisture content, nutrient composition, finesse, microbial load, etc. and mention the details on the packaging. Proper testing and labeling ensures suitability, safety and trustworthiness of the product.

Grinding fertilizer granules into powder allows their use for various modes of application where powder is required such as foliar spray, broadcasting and deep placement. Powder also has a higher surface area than granules for faster release of nutrients to the environment.

How to Mix Fertilizer Powder and What's the Mixing Process?

Some key points regarding mixing fertilizer powder are:

1. Determine nutrient requirements

Analyze the soil and determine the nitrogen (N), phosphorus (P) and potassium (K) requirements of the crops that will be fertilized by the mixture. The nutrient composition of the mixture should satisfy these requirements. This will guide selection of fertilizer powders and their proportions for mixing.

2. Consider properties of powders

Consider the nutrient composition, available nutrient content, moisture content, dustiness, flowability, etc. of the available fertilizer powders. Select powders having complementary properties that will result in the desired characteristics of the final mixture such as evenness, avoid lumping, flowability, etc. Powders with similar properties can also be mixed but additional measures may be required.

3. Calculate NPK analysis

Calculate the NPK analysis of each fertilizer powder by multiplying the percentage composition of N, P2O5 and K2O with their molecular weights to determine the available nitrogen, phosphorus and potassium. This will help in determining their proportions for the desired NPK ratio in the final mixture.

4. Decide mixing proportions

Determine the proportions of different fertilizer powders required to achieve the desired NPK ratio, total NPK content and other characteristics in the final mixture based on their properties and requirements. Adjust proportions as needed after testing the mixtures on a small scale.

5. Mix the powders

Mix the fertilizer powders thoroughly using means such as:

Mechanical mixing: Use a cement mixer, tumble mixer or similar machine to mix the powders mechanically. Add water 1-3% by weight for easier mixing if required. Ensure even mixing.

Manual mixing: Mix the powders manually on a clean, hard surface using shovels and turning repeatedly. Mix for at least 5-10 minutes until the color and smell become uniform.

Spraying and mixing: Spray water or a binder solution onto one powder at a time and mix thoroughly after each spray. Repeat spraying and remixing until a homogeneous mixture is formed. Use materials with similar moisture absorption capacity for this method.

6. Test the mixture

Test the mixed fertilizer for characteristics such as nutrient composition, moisture content, finesse, flowability, dustiness, etc. and ensure they meet the specifications before packing and sale or use. Make adjustments in proportions if any parameter is unsatisfactory. Multiple tests on different samples may be required.

Homogeneity test: Take samples from different parts of the mixed batch and test them separately. Similar results indicate homogeneity. Differences require remixing.

CCR test: Conduct the Crushed and Cracked Rice (CCR) test to determine the friability and flowability of the mixture. Mixtures with CCR value below 1% can be considered ideal. Higher values require adjustments.

Proper mixing of fertilizer powders based on requirements and their properties results in production of customized fertilizer mixtures suitable for targeted applications, crops and soils.

What's the Granulating Process for Producing Fertilizer Particles?

The granulating process for producing fertilizer particles typically includes the following steps:

1. Selection of binders

Choose suitable binder materials to bind the fertilizer powder particles together into granules. Common binders are clay, starch, agricultural lime, cement, etc. The binder should have binding capacity, be cheaper than the fertilizer and not affect its nutrient composition adversely.

2. Determining binder quantity

Calculate the quantity of binder required based on the quantity of fertilizer powder. A ratio of 5-10% binder by weight of powder is generally sufficient for granulation. Higher binder will increase hardness but reduce nutrient content.

3. Mixing binder and powder

Mix the binder material thoroughly with the fertilizer powder. Water is added (5-15% by weight of binder) and mixed to form a dough that can hold particles together. The dough should be firm but easy to knead and press. Add more water for a softer dough or powder for a harder dough based on the final granule size.

4. Kneading and pressing

Knead the dough for 3-5 minutes and then press it through a screen or die of the required mesh size to form granules. Softer dough will produce larger granules. Denser granules require more pressing force. Granules should not break easily. Allow pressed granules to air dry if required before screeing.

5. Rounding granules (optional)

If round granules are required, the pressed granules can be rounded using a rolling pin, granulator or briquetting press. Rounded granules have uniform shape, size and application characteristics. But nutrient content reduces slightly due to extra manipulation.

6. Drying the granules

Spread the granules in a single layer and dry them in a hot air oven at 50-60°C for 8-12 hours until they are hard. Faster drying using higher temperature (65-70°C) may cause cracks. Slower drying would produce a higher nutrient retention. Granules should not break on handling after drying.

7. Testing and packing

Test the granules for characteristics such as hardness, moisture content, nutrient composition, friability, etc. They should meet the required standards for the intended use. Pack the granules in pre-sterilized bags or containers and seal properly before sale or use. Proper testing and packing ensure safety, suitability and effectiveness of the granules.

8. Additional processing (optional)

Processed granules can be coated, pelleted or further enriched based on requirements. Coating protects from weathering while pelleting improves density and richness. Enrichment increases nutrient concentration for better response. Additional processing reduces friability but at the cost of higher nutrient loss. So decide processing judiciously based on benefits versus drawbacks for particular use.

In summary, selective mixing of binders, determining optimum quantities, kneading into dough, pressing into granules, proper drying and testing/packing are the key steps involved in granulating fertilizer powder. 

Granules have slower release, higher bulk density and longer shelf life than powder. 

Proper granulation technique and extent of processing results in production of granules suiting different requirements, uses and user preferences while maximizing nutrient retention and effectiveness.

How to Separate Qualified And Unqualified Fertilizer Particles?

Some common techniques used to separate qualified and unqualified fertilizer particles are:

1. Sieving

Pass the particles through sieves of different mesh sizes to separate them into fractions based on size. Qualified size particles pass through the required mesh size sieve while unqualified particles get retained. Sieves allow separation based on size without changing the chemical composition.

2. Screening

Use screens with different hole diameters or mesh counts to screen the particles into required size fractions. Round hole screens also allow separation of rounded particles. The screening process is similar to sieving. Screening can handle larger batch sizes than sieving.

3. Wet sieving

Sieve the particles after spraying them with water or soaking them in water. The wet particles have loose bonds and can pass through smaller mesh sizes, allowing separation into finer fractions. The separated fractions can be dried before use or sale. Wet sieving is useful for separating clay particles or round fertilizer granules into different sizes.


Mix the particles with a liquid such as water, brine or mineral oil and agitate to allow separation based on density. Qualified lightweight particles will float to the top while dense unqualified particles sink to the bottom. The floating and sinking fractions can be collected separately. Floatation is used for separation of inert, mineral or pelletized particles from organic fertilizers.

5. Winnowing

Blow air over the particles to allow separation based on differences in aerodynamic properties. The qualified round and smooth particles will be carried away by the air while rough and irregular unqualified particles fall into a collection container below. Winnowing requires the use of fans or blowers and works best for separating rounded fertilizer particles, seed grains or dust.

6. Magnetic separation

Pass the particles through a strong magnetic field to separate ferromagnetic impurities. The magnetic particles get attached to the magnets while non-magnetic qualified particles pass through. Magnetic separation works for removal of metal particles, iron rich impurities or residual magnetite from fertilizers. Electromagnets allow processing of non-magnetic as well as paramagnetic and diamagnetic particles.

7. Gravity separation

Allow the particles to settle in a liquid based on differences in settling velocity. The qualified rapidly settling particles settle to the bottom while unqualified slowly settling particles remain suspended or float. The settled and floating fractions can be collected separately. Gravity separation requires use of liquids with appropriate density and viscosity for effective separation of close particle densities. It is used for separating mineral, inert or pellet impurities from organic fertilizers.

8. Combination of techniques

Often, multiple separation techniques are combined for effective removal of impurities and production of pure fertilizer particles suitable for different uses. Proper technique selection and optimization leads to production of high quality fertilizers by separation and recovery of maximum qualified particles while removing all unqualified impurities.

Bio Fertilizer Making Machine (31)

How to Process The Qualified Fertilizer Granules After Screening?

Some common additional processing steps applied to screened fertilizer granules are:

1. Coating

Apply a coating material such as clay, starch, wax or polymer latex and allow it to dry to form a coating on the granule surface. Coating protects the granules from weathering, dusting and premature nutrient release during storage and application. Coated granules have a longer shelf life and sustained release of nutrients. Common coating materials and application techniques are:

Clay coating: Mix clay slurry or powder with water to form a paste and coat granules by tumbling and sticking the paste to their surface. Air dry the coated granules.

Starch coating: Soak granules in a starch solution and air dry them to form a starch coating. Starch coatings are organic and biodegradable.

Wax or polymer coating: Melt the coating material and dip granules in it to get an even coating. Coatings are applied as emulsions, solutions or hot melts. Granules are cooled and allowed to set.

Fluidized bed coating: Blow air through the granules in a fluidized bed coater to allow an even coating from a coating material sprayed from above. This results in a uniform coating with optimal thickness.

2. Pelletizing

Compress screened granules into pellets of required hardness and bind them together using binding agents such as clay, starch, molasses, etc. Pellets have very slow and controlled release of nutrients suitable as a basal application before plantation. Pellet production requires use of pellet presses. Nutrient contents reduce slightly due to compression and binding agent addition.

3. Enrichment

Add nutrition to the screened granules such as nitrogen, phosphorus, potassium nutrients or microbes to increase their concentration using appropriate enriching materials and techniques. Enriched granules meet higher nutrient requirements of crops and can be applied at lower rates. Common enrichment techniques are:

Nutrient coating: Coat granules with nutrients or nutrient solutions. Nutrients adhere to the granule surface, slowing their release.

Nutrient impregnation: Impregnate granules by immersing them in nutrient solutions and allowing them to absorb and retain the nutrients on drying.

Microbe inoculation: Inoculate granules with suitable microbes such as nitrogen fixers, phosphate solubilizers, etc. to enhance their effectiveness. Microbes grow and multiply within the granules, releasing nutrition to the environment on application.

NPK solution treatment: Treat granules by soaking or spraying them in nitrogen, phosphorus and potassium nutrient solutions. Nutrients get deposited over the granule surface and released slowly on application.

Compound/complex coating: Coat granules with compounds or chelates that release nutrients on hydrolysis such as urea formaldehyde or EDTA chelates. The coatings control the rate of nutrient release from the granules.

In summary, additional processing of screened fertilizer granules by coating, pelletizing or enrichment aims to modify their properties suiting specific requirements, uses or user preferences while maximizing nutrient utilization and effectiveness. Proper technique selection and optimization achieve production of high-quality customized granules at optimum costs and benefits.

How to Dry The Qualified Fertilizer Granules?

Some key points regarding drying fertilizer granules are:

1. Reduce moisture content

The main aim of drying granules is to reduce their moisture content to a level suitable for storage, transportation and application. Typical moisture contents after drying are 3-5% for granules to be stored for long periods and 8-12% for granules to be used within a short time. Lower moisture prevents caking, lumping and nutrient losses during storage while moderate moisture allows easy flowability and application.

2. Determine drying technique

Select a drying technique suitable for the granules based on properties such as moisture content, hardness, nutrient sensitivity, etc. Common techniques are hot air drying, drum drying, cyclone drying, fluidized bed drying, etc. Slower drying reduces nutrient losses while faster drying reduces energy consumption and dwelling time. Opt for a technique that achieves maximum moisture reduction with minimum drawbacks.

3. Hot air drying

Spread the granules in a thin layer in a baking tray or tray dryer and dry them in a hot air oven at 40-60°C. Slower drying at lower temperature (40-50°C) reduces losses while higher temperature (55-60°C) speeds up drying but increases losses. Hot air drying is suitable for diverse granule types but requires longer time and higher energy. Nutrient sensitive granules like coated or enriched granules require lower temperature (40-50°C) drying.

4. Drum drying

Spread the granules in a thin layer on a permeable surface rotating horizontal drum. As the drum rotates, hot air is passed from below, evaporating moisture from the granules. Drum drying dries faster at lower temperature than tray drying, reducing losses. It is suitable for large scale drying of diverse granule types including coated and enriched granules. Nutrient sensitivity requires lower hot air temperature (40-50°C).

5. Fluidized bed drying

Blow hot air through a bed of agitated granules in a fluidized bed dryer. The technique dries granules very fast at lower temperature (40-50°C) due to high surface area exposure, reducing losses significantly. It is most suitable for drying coated, enriched or drying-sensitive granules quickly while maximizing retention of added nutrition and quality. Higher air velocity and temperature may cause granule damage or nutrient losses.

6. Cyclone drying

An upward stream of hot air is passed through a cyclone, carrying the granules. As the granules rotate at high speed in the cyclone, moisture rapidly evaporates from their surface and is carried away by the air stream. Cyclone drying dries granules quickly at lower temperature (40-50°C), accelerating the process while reducing losses. It is suitable for diverse granule types including coated and enriched granules. Higher air speed may cause damage to delicate granules.

In summary, proper drying of fertilizer granules requires selecting a suitable technique, determining an optimal combination of parameters such as temperature, time and air flow and making necessary adjustments based on granule properties and requirements to achieve maximum moisture reduction with minimum nutrient loss, damage or other quality reduction. Balancing speed and temperature allows efficient drying at lower costs. 

Dried granules have improved flowability, reduced caking and longer shelf life, facilitating efficient transportation, storage and application.

How to Get The Dried Granules Cooled?

Some key points to consider while cooling dried fertilizer granules are:

1. Rapid cooling

Allow the dried granules to cool quickly after drying to prevent them from absorbing moisture from the air and caking or clumping together again. Rapid cooling below the saturation temperature of air prevents reabsorption of moisture. Slower cooling results in moisture gain and quality loss.

2. Ambient cooling

Spread the dried granules in a thin layer and allow them to cool at ambient temperature. Ambient cooling is suitable for granules cooled immediately after drying when the temperature is still high. But larger batches may take longer to cool, allowing moisture gain. Ambient cooling is economical but may reduce quality for bigger batches.

3. Forced air cooling

Blow cool air over the granules using fans to speed up cooling. Cool air is blown at a controlled rate and temperature to allow granules to cool quickly while preventing overcooling. Forced air cooling achieves rapid cooling even for larger batches, minimizing moisture regain and maintaining quality. But it requires equipment like blowers, ducts, fans, etc. and consumes more energy than ambient cooling.

4. Contact cooling

Spread the granules in contact with cool surfaces like concrete floors, metal trays or nets to allow heat transfer and fast cooling. The large surface area for heat transfer speeds up cooling. Contact cooling is more efficient than blowing cool air over the granules. But it requires provision of large cool surfaces, which may not be feasible. Granules in direct contact with surfaces can also stick together which requires difficult separation.

5. Fluidized bed cooling

Blow cool air through a fluidized bed of agitated granules to achieve fast and uniform cooling. Fluidized bed cooling is faster than other techniques due to enhanced heat transfer from increased surface area exposure. But it requires complex equipment and significantly higher energy consumption, incurring higher costs. Delicate granules may get damaged due to agitation and greater chances of clumping exist. However, it is a good option for bulk volumes of uniform durable granules.

6. Spray cooling

Spray the granules with cold or room temperature water to instantly cool them. The heat of evaporation absorbs heat from the granules, reducing their temperature rapidly without overcooling. Spray cooling is very fast but wets the granules, requiring additional drying. It is only suitable for granules with high moisture tolerance that can withstand re-drying without damage or loss. Water spray method may not be feasible for certain granule types.

In summary, proper cooling of fertilizer granules requires selecting a suitable technique based on granule properties, batch size, requirements, cost and feasibility while balancing speed and preventing quality loss. 

Techniques like ambient, forced air and contact cooling are suitable for smaller volumes while fluidized bed and spray cooling work for bulk quantities. 

Maximum heat transfer at controlled rates allows economical and effective cooling without damage to granules, maintaining or improving quality.

How to Make Your Fertilizer Particles More Colorful?

There are several ways to make fertilizer particles more colorful:

1. Add natural color pigments

Add natural coloring pigments such as iron pyrites, lime stone dust, red soil, sand, bentonite clay, etc. to the fertilizer particles based on the required color tone. These pigments are inexpensive, non-toxic and provide color without affecting the nutrient composition of fertilizer. Pigments provide opaque and bright color shades. Use them at 1-5% by weight of fertilizer particles.

2. Add molasses

Add molasses at 2-5% by weight of fertilizer particles. Molasses acts as a pigment and binder, providing brown color tones and better granulation. It also improves moisture retention, shelf life and weed suppression ability of fertilizer. Darker shades can be obtained by adding more molasses. Molasses color disappears on application, not affecting the appearance of fertilized soils.

3. Add vegetable dyes

Apply vegetable based dyes such as turmeric powder, beetroot juice, pomegranate rind extract, etc. to fertilizer particles to get light pastel colors. Dye the particles thoroughly by soaking, spraying or shaking to ensure even color distribution. Use 1-2% dye by weight of fertilizer for 50-100% color coverage with moderate tinting. Vegetable dyes provide vivid shades but may fade with weathering and in damp conditions. Reapply dye for maintaining color intensity.

4. Add latex or emulsion paints

Apply latex, acrylic or emulsion paints to fertilizer particles to get any desired color shade. Ensure the paint and fertilizer composition are compatible to avoid aggregations. Apply paint in thin coats, allowing each coat to dry completely to achieve even and adhesive coloring. Use 2-5% paint by weight of fertilizer for 30-100% color coverage depending on number of coats. Paint provides high color intensity, gloss and weather resistance but may reduce porosity, moisture absorption and nutrient release of fertilizer slightly. Compatibility tests are required before large scale application.

5. Combine techniques

For more vibrant and deeper shades, combine the techniques by applying pigments and vegetable dyes together or paints over pigments or dyes. Additives like molasses also enhance the effects and benefits when combined with other techniques. Combining techniques allows expression of a wider range of colorful shades and variants while optimizing properties and maximizing benefits. Proper selection and ratio of additives achieve the desired shade with ideal characteristics.

In summary, adding natural pigments, molasses, vegetable dyes or paints are effective techniques for enhancing the color appeal of fertilizer particles without affecting their quality, characteristics and effectiveness in a significant manner. 

Proper additive selection, optimization of quantities and combining techniques allow customized coloring to match user preferences while suiting requirements. Colored fertilizers have higher visual attraction, appeal and acceptance among farmers and customers.

How to Pack your Fertilizer Particles Automatically?

Attractive, labeled packs have higher shelf appeal, appeal and acceptability. They indicate quality, legitimacy and recommendations, encouraging purchases.

Improved safety: Automated packing under contained conditions prevents direct contact or exposure of operators to fertilizer particles, dust, fumes or chemicals, reducing health and safety risks. Proper packaging also minimizes hazards of spillage, leakage or explosion during storage, transportation or application.

Some common techniques used for automatic packing of fertilizer particles include:

• Auger or screw packing

Screws feed the fertilizer particles into molds or pouches at a controlled rate for uniform packing. Augers can precisely control the weight or volume of each pack. Materials with moderate moisture and low dustiness are suitable for auger packing.

• Vibratory or gyratory packing

}Vibrations are applied to help settle the particles into molds or pouches at high speeds for continuous packing. Purging of air and consolidation of particles results in dense and consistent packing. Allows processing of diverse particle types including coarse, dusty or moist materials. Requires vibration generation and application equipment.

• Membrane or flow packing

A flow of air or inert gas is applied under the fertilizer bed to fluidize it and push the particles towards molds or pouches for packing. Even packing is achieved by controlling the rate of fluidization and flow. Suitable for processing hygroscopic, dusty or segregative materials that cannot flow freely under gravity. Requires equipment for fluidization medium supply and control.

• Rotary drum packing

Particles are fed into a rotating drum with molded recesses for packing under compression. Rotation distributes the particles evenly in each recess before final compaction for packing. Produces firm and uniform packs through consolidation. Can process diverse particle types at high speeds with minimal segregation or damage. Requires a motor and adjustments for drum rotation speed and fill time.

• Bottle or bag filling

For liquid or powder fertilizers, filling equipment with volumetric counters or weighing scales can be used to fill bottles, jerrycans or bags automatically to the required capacity. Sealing the containers retains quality until use. Silo feeding provides continuous filling at high speeds for large scale operations. Gravimetric or volumetric controls ensure accurate and consistent filling.

In summary, automated packaging techniques allow faster, more uniform, safer, hygienic and attractive packing of fertilizer particles and formulations. Proper selection of technique based on material properties and requirements ensures high productivity, quality, shelf life and brand value. Continuous improvement and optimization lead to economical and effective automated packaging, improving competitiveness.

Different Fertilizer Shapes Produced by Bio Fertilizer Making Machine

Several different shapes of fertilizer particles can be produced using bio fertilizer making machines including:

1. Granules

Granulation is the most common method for producing particle fertilizers. Bio fertilizer granules typically have sizes in the range of 1 to 8 mm. Granules have higher bulk density, harder texture, lower surface area and slower nutrient release than powders. They are suitable for basally applying nutrients to crop roots. Granules can be round, oblong or irregular in shape depending on the granulating technique and binder used.

2. Pellets

Pellets are produced by compressing and binding granules together into oval or cylindrical shaped particles typically 2 to 10 mm long and 0.5 to 3 mm in diameter. Pellets have the slowest release of nutrients, suitable as a basal application before crop plantation. They have very high bulk density and hardness, able to withstand handling, transportation and mechanical application without damage. Pellets can be cylindrical, tapered or flat-oval in shape.

3. Crumbles

Crumbles are irregularly shaped aggregates produced by agglomerating fine powders or granules into loose clusters. They have sizes ranging from 1 to 8 mm. Crumbles combine the advantages of higher bulk density, cost efficiency and handling convenience of granules with faster nutrient release of powders. They have lower hardness than granules, able to disintegrate more easily in soil for improving availability of nutrients to crop roots. Crumbles have irregular, crumbly shapes with jagged edges.

4. Chips or prills

Chips and prills refer to fertilizer particles in the form of small pellets, typically 2 to 5 mm long. They are produced using a process similar to pellets but with some modifications to obtain smaller, irregular and porous particles. Chips have lower density and hardness than pellets but higher than granules. They provide a moderate slow release of nutrients, suitable as a basal as well as top dressing application. Chips tend to have flat or teardrop-shaped oval profiles with smooth or slightly rough surfaces.

5. Coated granules or seeds

Coating the surface of granules or seeds with fertilizers or their solutions provides additional nutrition to the soil through slow release as the coating dissolves or wears off. Coated particles maintain the original shape and size of the granule or seed core. Coatings can provide basal nutrition as well as supplements, improving utilization efficiency. They are suitable for use as both basal and top dressing applications. Coated particles have rounded, oval or irregular shapes depending on the base material.

In summary, bio fertilizer machines can produce fertilizer particles in a variety of shapes, sizes and aggregation levels with different release characteristics based on process parameters and binders used. 

Proper selection of shape, size and aggregate results in optimized performance, user convenience and cost efficiency for diverse applications. 

Shape, texture and release pattern of particles influences their handling, sowing, effectiveness and competitiveness in the market based on prices and demand.

Periodic inspection identifies any weak or improperly sized belts that require replacement to maintain performance and safety. Replace all hoses and tubing if they start developing cracks or become porous, swollen or bent with age or under high pressure conditions.

6. Lubricant and solution change

Change lubricating greases, oils and other solutions completely based on their recommended change intervals or if onset of undesirable properties becomes evident like accumulation of residue, color change or foul smell. Degraded or contaminated lubricants and solutions no longer serve their purpose effectively and may even damage components or lead to problems. Use only recommended grades of lubricants and solutions for best results.

7. Gasket and seal replacement

Inspect all gaskets, seals, O-rings and washers regularly for any damage like tears, cracks, swelling or permanent deformation and replace as needed. Damaged seals no longer provide an effective seal, leading to leakage, contamination or impaired performance. Replace seals that start showing signs of damage or decline in flexibility/ adaptability. Replaced seals must be of the same grade as originals.

8. Calibration

Calibrate control mechanisms periodically or based on their specified recalibration intervals to ensure continued precision and accuracy. shifted or inaccurate control settings lead to variation in quality, reduced efficiency, damage to components or complete system failure. Calibrate based on certified standards for optimal performance and quality.

Regular maintenance work protects a bio fertilizer making machine from premature damage and decline ensuring continued efficient, safe, high quality and cost effective operation over its working life. 

Addressing issues early on avoids expensive repairs, accidents, contaminated/ wasted product batches and loss of reputation or customers.

How to Use a Bio Fertilizer Making Machine to Make Your Own Fertilizer Pellets?

Here are some steps to use a bio fertilizer making machine for making fertilizer pellets:

1. Select the ingredients

Identify the ingredients you want to use to make the bio fertilizer pellets. This can include manure, compost, green sand, rock phosphate, neem cake, banana pseudostem, etc. based on the nutrients needed and crop you want to fertilize. Ensure the ingredients are dry, ground properly and have a moisture content below 15% before processing.

2. Determine mixing ratios

Decide on the proportions of each ingredient you want to mix to make a balanced fertilizer pellet with nutrients in the required ratio. The NPK ratio depends on the crops and growing stages. You may need to test different ratios to get the right combination. Factor in the nutrient content of each ingredient.

3. Process and mix the ingredients

Feed each ingredient into the machine hopper separately and adjust the feed settings to the required proportions. Ensure even mixing as the ingredients travel through the processing unit. Add water gradually and in small amounts if needed to reach the ideal moisture for pelleting which is around 10-15%. But do not overwet.

4. Check for binding

Once the ingredients have mixed, start the pelletizer to form pellets. If the pellets do not bind together, increase the binder quantity or switch to a different binder like molasses, clay or gum. Under-binding leads to crumbling pellets while over-binding makes pellets too hard. Get the right proportion for your specific ingredients.

5. Dry and cure the pellets

Separate and spread the pellets on a raised mesh platform in a shady, well-ventilated area. This allows air circulation for drying. The pellets require 3 to 7 days of drying and curing before bagging for use. Curing helps the pellet ingredients bind tightly together for durability. Cover pellets if drying outdoors.

6. Bag and label the pellets

Once pellets are dried and cured, bag them in moisture proof bags. Clearly label the bags with information on ingredients used, NPK ratio, dosage and instructions for use. Properly bagged and labeled pellets can be stored for up to 6 months before use.

7. Use the pellets as fertilizer

Use the bio fertilizer pellets as a basal dressing or top dressing based on the instructions. Apply pellets around the drip line or root zone of plants at the specified dosage. Water the pellets immediately after application to aid dissolution and improve nutrient absorption. Pellets release nutrients slowly, providing sustained nutrition to the crop.

The steps described above can be followed to use a bio fertilizer making machine for producing your own customized fertilizer pellets.
