Organic fertilizer products yileds improvement

In a complete organic fertilizer manufacturing process for manure fertilizer production, fermentation, granulation and crushing are three key steps. Therefore, fermentation stacker, organic fertilizer granulator and organic fertilizer crusher play an important role in all organic fertilizer equipment. Let’s discuss the problems that may be encountered in the production process of these two key links.

How to improve the product output and output, the key lies in the organic fertilizer granulator.

1、 According to the moisture, fineness and cohesiveness of raw materials.

1. Moisture

Powder raw materials form spherical particles through the attachment of water. Therefore, controlling water and making water uniform have become the key factors to improve yield. The lower the moisture content, the lower the granulation rate, the higher the moisture content, the more large particles, the uneven moisture, the smaller the particle size, and the lower the yield.

2. Material fineness

It is needless to say that the material fiber has natural coarse granulation effect, rough and brittle appearance and poor formability. The higher the fineness, the better the formability and the smoother the particles.

3. Is the material sticky

In particular, organic fertilizer granulation, general raw animal manure (chicken manure, pig manure, cow manure, sheep manure, pigeon manure, etc.), straw (corn straw, straw, leaves, etc.), fungus residue, sugar residue, drug residue, monosodium glutamate residue, etc. The viscosity of general materials is poor, so some viscous fillers such as bentonite need to be added.

2、 Fertilizer granulator is selected for organic fertilizer production line.

For example, the production of granules can choose disc granulator, new organic fertilizer granulator and drum granulator.

If columnar is produced, ring mold granulator and columnar extruder are selected.

For irregular and flat ball type, select the appropriate drum extrusion granulator (depending on the die).

All kinds of granulation equipment have their own advantages and disadvantages. Different equipment shall be selected according to raw materials, investment cost (drying or not) and the needs of farmers.

3、 Equipment operation

1. For example, the disc granulator can pass the inclination of the disc. The more flat the disc is, the larger the particles are, the steeper the disc is, and the smaller the particles are.

2. According to the control of material moisture, the larger the moisture, the larger the particles, the smaller the moisture, and the smaller the particles.

3. According to the speed, the higher the speed, the smaller the particles, and the lower the speed, the larger the particles.

In general, the uneven particles of organic fertilizer are mostly caused by the uneven mixing of materials and the thickness of material fiber.

Quality Bio Fertilizer Production Tips

The production equipment of biological fertilizer project mainly includes fermentation part and granulation part. Even if organic fertilizer raw materials are well fermented, granulation is difficult, because organic raw materials are characterized by rough raw materials, light weight and low binding rate.

Different organic raw materials have different characteristics, so special care should be taken when selecting equipment, otherwise it will not only affect the output, but also the appearance of the product can not meet the requirements.

The bio organic fertilizer production line includes main equipment:

1. New type organic fertilizer granulator: designed and manufactured by the new process of wet continuous granulation. The machine can not only granulate a variety of organic materials, especially coarse fiber materials that are difficult to granulate by conventional equipment.

2. Tipping machine: used for tipping and composting to improve fermentation speed and quality.

3. Horizontal mixer: this series of horizontal mixer is a new generation of mixing equipment developed by our company. High mixing degree and low residue, suitable for the mixing of organic and inorganic fertilizers.

4. Conveyor: it is suitable for conveying loose materials or box items in coal, metallurgy, mining, chemical industry, building materials, wharf, warehouse and construction site, especially in chemical fertilizer plant, cement plant and other environments.

5. Packaging scale: the packaging scale is mainly composed of automatic quantitative packaging scale (composed of storage hopper, feeder, weighing bag hopper, pressing mechanism, computer control, pneumatic actuator, etc.) and optional items (conveyor, sewing machine, etc.)/ Heat sealing machine).

There are several key factors to pay attention to in the selection of equipment: fermentation mode, organic raw materials, degree of mechanization and annual output. The quality of organic fertilizer depends on the fermentation site and the formula of the product.

The key factors of fermentation are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water, pH value and aeration control. If a factor is not well controlled, it will cause incomplete fermentation, incomplete fermentation or too long fermentation time.

The formula of organic-inorganic compound fertilizer is the same as that of inorganic fertilizer. It also depends on different soils and different crop formulations. If the fermentation is properly prepared, the effect is better than inorganic fertilizer and the cost is low. As a green fertilizer, it can also improve the environment of plant survival and soil granulation.

Latest Technology for Bio Fertilizer Production

The technical content of biological fertilizer project is high. In addition to the biological agents that promote the maturation and decomposition of organic matter in the maturation process, in order to achieve targeted maturation and deodorization, microbial products with specific functions need to be added to enhance the effect of the products.

Pan Granulation Fertilizer Production Line

At present, bio organic fertilizer is included in the category of microbial fertilizer in China, and more strict management measures are implemented than organic fertilizer to promote the healthy development of organic fertilizer.

1. The production process of bio organic fertilizer production enterprises registered with the Ministry of agriculture is basically engaged in the production of microbial fertilizer. In the process of fermentation production, tank stacked fermentation is mostly used, and there are other fermentation methods, such as flat stacked fermentation and fermentor fermentation.

In the process of fermentation and maturation, the adjustment of material moisture, carbon nitrogen ratio and temperature and the use of curing agent are the production process. The key is that the application of fungicide directly affects the fermentation cycle and the maturity of materials. The ripening material basically achieves the harmlessness of the product and is also conducive to the survival of the functional bacteria added in the post-treatment process.

2. In terms of post-treatment of fermentation materials, most enterprises add functional bacteria for compound molding. The dosage form of the product is mainly powder, and some are granulated by rotary drum fertilizer granulator or roller granulator. Granular products prevail over powdered products. The disadvantages of poor appearance and low grade not only improve the commerciality of the product, but also increase the production cost of the enterprise, which has a certain impact on the survival of effective bacteria.

3. The utilization of strains and microbial strains is the core of bio organic fertilizer products. In the production process, there are generally two links related to the utilization of microorganisms:
First, add decomposition bactericide to promote material decomposition and decompose and deodorize in the decomposition process. It is mainly composed of complex strains.

Common strains include photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes, Penicillium, wood fungi, etc; Second, the functional bacteria added after material decomposition, generally nitrogen fixing bacteria, phosphorus solubilizing bacteria, silicate bacteria, lactic acid bacteria, Pseudomonas, actinomycetes, etc., play a specific role as fertilizer in the product.

Therefore, the selection and use of microbial strains for the production of bio organic fertilizer is a core technology. Only by mastering this key technology can we accelerate the decomposition and maturity of materials, Ensure the application effect of the product.

7 detailed process to make compound fertilizer

Process design description of NPK fertilizer production line:
1. Batch processing:
Electronic batching or disc batching.
2. Crushing process:
The mixed fertilizer proportioned according to the design requirements is sent to the raw material crusher for raw material crushing. The purpose is to crush various raw materials to a certain fineness. Basically, the particle size of raw materials is less than 1mm, which is conducive to the material in the granulator. Roll inside to meet the standard ball.

20t per hour drum granulation plant layout

3. Granulation process:
The crushed mixture is conveyed to the fertilizer granulator through the conveyor. The liquid phase provided by the slurry or water in the extrusion granulator makes use of the centrifugal force brought by the rotation of the fertilizer granulator to turn the material into organic fertilizer. At present, it is better to use the disc granulator to produce organic fertilizer. The granulation rate of disc granulator can reach more than 90%, but the table output is low.
4. Drying process:
The granular materials are transported to the rotary three drum dryer through the conveyor. The hot blast stove is set at the inlet of the dryer to provide heat for the drying of materials in the dryer and evaporate the water in the formed materials into water. The steam is introduced into the dust collection chamber through the fan to remove dust. After the material enters the dryer, the liquid phase of the material is high and the ball strength is low. In order to ensure the sphericity of the material, we used it in the design of the dryer.
5. Cooling process:
The moisture content of materials after drying generally can not meet the water content requirements of organic fertilizer. Cooling in the cooler is very important for the NPK fertilizer manufacturing process.
6. Screening process:
The cooled organic fertilizer still has a certain temperature. After the organic fertilizer material enters the screening machine, the organic fertilizer material is roughly classified, and the screened fine powder is directly returned to the granulator for granulation. After screening, the screened coarse material is crushed by the return chain crusher, and then returned to the granulator for re granulation. The finished product is directly sent to the silo of the packaging scale. On the other hand, compound fertilizer materials are also used for screening projects. Cooling engineering plays a certain role in reducing temperature and preventing material caking.
7. Packaging process:
The coated finished organic fertilizer enters the silo of the packaging scale, automatically counts according to the set quantity, then puts it into the packaging bag, and then through the automatic sewing system, the sewn compound fertilizer can be stacked in the silo. Warehouse. In principle, the height of each stack shall not exceed 8 bags and the height shall not exceed 10 bags. The ground must be damp proof.

Formular for npk fertilizer production

From a technical point of view, the important factor in the formulation design of extrusion granulation products in NPK fertilizer production line is the characteristics of materials. Next, we discuss another aspect of the influencing factors, that is, the influence of the type of raw materials on the formula.

1. Material compatibility

Theoretically, any proportion of NP or K base fertilizer can be prepared, and trace elements and even pesticides should be added if necessary. However, materials must be limited by compatibility. The substances in the formula shall not have chemical reaction in the process of fertilizer manufacturing, and occasional reaction shall not be allowed.

2. Effect of urea on formula

The international fertilizer center has done a lot of experiments on the effect of urea on the performance of compound fertilizer, although the report does not mention the same example as the product formula we are studying, and most experiments do not carry out granulation on extrusion. Yes, but its conclusion is still useful to us.

Because urea absorbs moisture easily, the critical relative humidity of NPK compound fertilizer decreases significantly. At the same time, the international fertilizer center also found that this effect is more serious when potassium chloride is used as the potassium source of compound fertilizer.

Due to the low critical relative humidity, urea based compound fertilizer is easy to absorb water, which blocks the screen, pipeline, chute, etc.
When the temperature increases, the critical relative humidity of urea based compound decreases rapidly.

The production capacity of the dryer must be determined by many factors. Some urea based NPK fertilizers begin to soften at 70 ℃. If the outlet temperature of the dryer is higher than this temperature, the fertilizer particles will be too soft, the granulation process will be out of control (the particles are too large), and the internal scabs will form. Drying causes difficulties in screening and transportation.

In the same report, the international fertilizer center also tested other aspects of urea, such as water absorption, moisture permeability, water holding capacity, particle integrity, fluidity and agglomeration. The result is negative, which will have an adverse effect.

In short, the formula design test and production of extrusion granulation products in compound fertilizer production line show that the use of urea in compound fertilizer will encounter great trouble, not only because it affects the storage and transportation performance of products, but also because it also has a certain impact on the production process.

How to dry compound fertilizer granules?

Drying process is also the key of NPK fertilizer production line. The fertilizer should be dried after granulation to reduce the moisture in the particles and increase the hardness of the particles, which is very important to the quality of the fertilizer.

1. The installed dryer shall be subject to an empty machine test for not less than 4 hours. In case of any abnormality during commissioning, it shall be handled in time.

Rotary Drum Dryer Used in Fertilizer Production Line

2. After commissioning, retighten all connecting bolts, check and supplement lubricating oil. After the test is normal, the load test can be carried out.

3. Before load test run, single air test run shall be conducted for each auxiliary machine. After the single machine test is successful, transfer to the joint test.

4. Ignite the hot air oven to preheat the dryer and start the dryer at the same time. Do not rotate the cylinder to prevent the cylinder from bending.

5. According to the preheating condition, the wet material is gradually added into the drying cylinder, and the feeding amount is gradually increased according to the moisture content of the discharged material.

6. The preheating of the dryer needs a process, and the hot blast stove should also have a preheating process. Sudden fire is prohibited. Prevent local overheating and uneven thermal expansion and damage.

7. Fuel combustion value, thermal insulation quality of each part, moisture content of wet material and uniformity of feeding amount affect dry product quality and fuel consumption. Therefore, it is an effective way to improve economic benefits to make each part reach the state as much as possible.

8. In the working state, the roller frame shall be filled with cooling water.

9. All lubricating parts shall be filled in time.

10. During shutdown, the hot blast stove shall be closed first, and the drying cylinder shall continue to rotate until it is cooled to close to the outside temperature.

11. It is forbidden to stop at high temperature to prevent the cylinder from bending and deformation.

12. In case of sudden power failure, close the hot blast stove immediately, stop feeding, and turn the cylinder half a circle every 15 minutes until the cylinder cools down.

The operating procedures of this fertilizer manufacturing process should be careful and professional. Failure to follow this procedure will cause the cylinder to bend.

Detailed process for bio fertilizer production

The biological fertilizer project is made of organic wastes such as crop straw (such as straw and wheat straw), edible fungus nutritional residue, inorganic minerals (salts such as salt mine and phosphate mine), animal manure (chicken manure and cow manure) as raw materials for bio fertilizer production, and then mixed with a certain amount of microbial flora, accumulated, high-temperature fermentation, decomposition, sterilization, amino acids, nitrogen and phosphorus, Potassium and other nutrients needed by crops are nutrients for crops to absorb.

In short, it is divided into the following steps:

Pretreatment: after the compost material is transported to the storage yard, it is weighed by a balance and sent to the mixing and mixing device. It is mixed with the production and domestic organic wastewater in the plant, and compound bacteria are added.

The fertilizer moisture and carbon nitrogen ratio are roughly adjusted according to the raw material composition. After mixing, proceed to the next step.

One time fermentation: the mixed raw materials are sent to the fermentation tank by the loader and stacked into a fermentation pile. The fan is used for forced ventilation and oxygen supply from the bottom of the fermentation tank. At the same time, the compost dumper is used for 2 days.

Add water (mainly produced in the factory, mainly domestic organic wastewater) and nutrients, control the fermentation temperature at 50 ℃ ~ 65 ℃, aerobic fermentation. The first fermentation cycle of the project is 8 days. After each pool of raw materials and one pool of daily semi-finished products, the fermentation semi-finished products are discharged and ready to enter the next process.

Post treatment: the finished compost is further screened, and the screened materials are treated according to the water content. After granulation, the particles are sent to the dryer heated by biogas in the biogas digester for drying, medium and trace elements are added in proportion, then mixed into finished products, packaged and stored in the production of bio organic fertilizer.

The process has been sold. The screened materials are returned to the crushing process for reuse.

Medicine residue to make organic fertilizer

Traditional Chinese medicine residue is mostly the residue after chopping or crushing roots, stems, leaves and seeds, and the effective components are extracted through special processes. It is a good raw material for various wastes in organic fertilizer production process and conventional ecological organic fertilizer production projects.

The advantages of making organic fertilizer from traditional Chinese medicine residue are:

1. Increase crop yield and improve the quality of agricultural products. In addition to nitrogen, phosphorus, potassium and other nutritional components, fermented drug residue also contains a variety of sugars, amino acids and other substances, which not only provide nutrients for crop growth, but also promote microbial activities and maintain micro ecological balance. Soil.

2. Fermentation residue fertilizer contains a large number of beneficial microorganisms. After use, it can improve soil, improve crop root absorption and prevent diseases.

3. Secondary utilization, turning waste into treasure, reducing the use cost of chemical fertilizer and avoiding environmental pollution.

The organic content of traditional Chinese medicine residue is often more than 70%. According to the latest organic fertilizer standard, the total nutrient content of traditional Chinese medicine residue is usually not up to standard.

If the traditional Chinese medicine residue fermentation is used as raw material to produce organic fertilizer, nitrogen and phosphorus can be added to the traditional Chinese medicine residue. Chemical fertilizer or potassium fertilizer, or binary or ternary compound fertilizer, and then add biological fermentation bacteria to fully ferment and crush, which is the standard organic fertilizer. Different residues have different fermentation ratios.

Add the drug residue into the organic matter with high crude protein content such as livestock and poultry feces, bone meal and animal corpses, and add biological fermentation bacteria. Stack it with organic fertilizer dumper, stir it evenly and ferment for several days. During the fermentation process, the temperature rises continuously.

When the temperature reaches above 45 ℃, turn it over every 2 ~ 3 days, and the temperature of the stockpile can be maintained between 50 ~ 70 ℃. When the temperature drops slowly, stop turning the pile and let it stand for about a week to basically complete the decomposition and fermentation. After decomposition, it is crushed by the crushing device to obtain powdered organic fertilizer.

Nowadays, compared with powdered organic fertilizer, the best-selling organic fertilizer in the market is relatively easy to store and spread, and is favored by customers. If granular fertilizer is to be made, the powdered fertilizer shall be granulated by a fertilizer granulator to obtain granular fertilizer. Then it is dried, cooled, screened, and finally packaged for storage.

Flat Die Granulator for Organic Fertilizer Production

The production process of organic fertilizer is mainly to granulate and dry the organic waste with water content of about 30% decomposed by fermentation, prepare round organic fertilizer by granulation and drying, add functional bacteria to produce biological organic fertilizer, and add nitrogen, phosphorus and potassium (total nutrient content is less than 15%) to produce organic and inorganic fertilizer.

After screening the fermented organic waste, the binder raw materials and other components to be compatible are measured and proportioned in proportion, and quickly mixed by the bucket elevator into the fertilizer mixer for rapid mixing.

The material slides out of the mixing bin and is evenly and continuously fed into the flat die extrusion fertilizer granulator by the disc feeder to form columnar particles; Cylindrical particles (equal in diameter and length) are polished by a circular particle polishing machine. The spherical particles are sent to the drying, cooling and screening machine by belt conveyor.

The particles are dried at low temperature and large air volume in front of the drying cooling screening machine, and then enter the cooling section for air blowing. The cold and completely cooled materials enter the screen installed at the end of the cylinder, screen out the powder and large particles, and return to the mixed granulation system; The finished product particles are transported to the finished product silo by the elevator, measured, packaged and warehoused.
