fertilizer granulator Mar 13, 2023

The organic fertilizer manufacturing process is mainly to screen and magnetically sort the organic waste with a water content of about 30% to 35% after fermentation and decay to prepare round granular organic fertilizer, and add functional bacteria to produce biological organic Fertilizer, adding nitrogen, phosphorus and potassium (total nutrient content less than 15%) can produce organic and inorganic fertilizers.

After the fermented organic waste is subjected to magnetic separation and sieving, the raw materials with binder and other ingredients to be compatible are metered according to the ratio requirements, and then lifted into a multi-dimensional high-efficiency mixer by a bucket elevator for rapid mixing. The mixed material slips out into the mixing bin, and is continuously and uniformly fed into the extrusion granulator by the disc feeder to make cylindrical particles; the cylindrical particles are polished and formed into spherical particles by the circular particle polishing and shaping machine, and are formed by the belt. The machine is fed into the drying, cooling and screening machine (three-in-one model). The particles are dried at a low temperature and large air volume (≤65 ℃) in the front section of the drying and cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling The material enters the screen installed at the end of the cylinder, and the sieved finished particles are transported by the elevator to the finished product silo, which is measured and packaged by the packaging system; the sifted large particles are returned to the mixing granulation system after crushing; The sieved small particles (basically without powder) can be made into small packages and sold directly.

Fertilizer manufacturing process of sheep manure and straw material fertilizer

The amount of sheep dung mixed with the appropriate amount of straw powder depends on the water content of the sheep dung. Generally, the fermentation requires 45% water content, that is, the hands are squeezed into a lump, and the fingers are watered, but there is no dripping. Scattered. Then add cornmeal and strains. The function of cornmeal is to increase sugar content for the fermentation of strains, so that multi-dimensional compound enzyme bacteria will soon have an absolute advantage.

1. Add the prepared mixture to the blender for stirring. The stirring must be even, transparent, and no raw materials are left.

2. The well-stirred ingredients are piled into long strips with a width of 1.5m-2m and a height of 0.8m-1m, and they are tossed once every 2 days with a turning machine.

3. Compost for 2 days, odorless for 4 days, loose for 7 days, become fragrant for 9 days, and become fat for 10 days.

4. The temperature can reach 60 ℃ -80 ℃ on the second day of stacking, killing E. coli, eggs and other diseases and insect pests;

5. On the 4th day, the smell of sheep dung was eliminated; on the 7th day, the compost became loose and dry, covered with white hyphae;

6. On the 9th day, a scent of distiller’s koji is issued;

7. On the 10th day, the bacterial manure will ferment and mature;

8. After a little drying, it can be crushed by a semi-wet material crusher, granulated by an organic fertilizer granulator, dried by a dryer, and then sieved by a sieving machine. The finished organic fertilizer is ready to be installed. The bag is stored.

Precautions during fermentation of organic fertilizer production line

fertilizer granulator Mar 13, 2023

Matters needing attention during the fermentation of organic fertilizer manufacturing process:

1. Requirements for fermentation raw materials

Fermentation raw materials (such as agricultural wastes such as feces) are preferably fresh without natural recycling.

2. Accessories requirements

Fermentation auxiliary materials (such as straw, rice bran, etc.) should have a moderate water content, strong water absorption, suitable particles or length, and should not be too large. The amount of addition should be determined according to the moisture content of the fermentation raw material.

3. The strains should be removed

Organic fertilizer fermentation strains require at least 50 grams (1 or 2) for one ton of raw materials. Considering that it cannot be evenly spread on the fermentation materials, when using it, first mix 50 grams of strains with 500 grams (1 kg) Stir any kind of raw materials such as wheat drum, sawdust, oil dry, rice bran, etc., and then sprinkle it into the fermentation material, and then stir and pile up the fermentation evenly.

4. The fermentation moisture is adjusted well

The moisture adjustment of raw and auxiliary materials is the most important, which is related to the success or failure of fermentation. Moisture requirements are: after the original accessories are mixed, hold them in a ball and fall on the ground into two pieces. The proportion of general auxiliary materials (such as straw, rice straw, etc.) is 10% to 30% (weight percentage with raw materials). If calculated according to the volume ratio of the two, it is generally 2 parts of raw materials and 1 part of auxiliary materials.

5. The length, width and height of the fermentation stack should meet the standard

It is required that the width of the fermentation product is not less than 1.5 meters, the height is not less than 1 meter, and the length is not limited.

Input of a complete set of granular organic fertilizer production line equipment and supporting facilities

1. Centralized treatment scheme of livestock and poultry excrement: build a relatively large excrement treatment station in the centralized breeding area of scale (one machine with multiple tanks). For daily treatment of livestock and poultry excrement of more than 12 tons, use a 3M span trough tipper; Build a 300-500 square meter transparent greenhouse, with several fermentation tanks built in the greenhouse (the cost depends on the local actual situation due to different materials).

2. Dispersed treatment scheme of livestock and poultry excrement: 2M span fermentation equipment is built in two farms, and the single unit price is about 200-300 square meters of glass fiber reinforced plastic shed (the cost depends on the local actual situation due to different materials)

So how to use livestock manure and crop straw to ferment organic fertilizer:

1、 Material ratio. Mix chicken manure, pig manure, mushroom residue, straw, dry soil powder, etc. in proper proportion. About 3-4 tons of fresh manure are added with 1 kg of organic fertilizer starter. The starter is diluted and evenly scattered into the manure pile, and mixed evenly.

2、 Material stacking. When making a pile, making it too small will affect the fermentation. The height of the pile is 1.5 meters to 2 meters, the width is 2 meters to 3 meters, and the length is more than 3 meters, so the fermentation effect is better.

3、 Moisture requirements. The moisture content of fermentation materials should be controlled at about 65%. Too high or too low is not conducive to fermentation, and fermentation is slow with little water; Too much water, poor ventilation, slow temperature rise and odor. If the water content is too high, straw, mushroom residue, dry soil powder, etc. can be added. If the water content is appropriate, you can grasp a handful of materials tightly, see the watermark on the finger joint, but do not drip, and disperse immediately after landing.

4、 Turn over the pile for ventilation. During the fermentation process, oxygen should be properly supplied and the pile should be turned over (several times when the temperature rises to 75 ℃ or above). The temperature of the pile should be controlled at about 65 ℃. Too high temperature has an impact on nutrients. Fifth, fermentation is completed. Generally, the fermentation can be completed in 5 to 7 days. The material is dark brown and the temperature drops to normal temperature, indicating that the fermentation is completed.

The complete set of granular organic fertilizer production line equipment includes: trough fermentation equipment – forklift silo – pulverizer – mixing mixer – disc granulator – dryer – cooler – screening machine – coating machine – packaging machine, and the equipment is connected by conveyor.

What is the role of fermented organic fertilizer (chicken manure for example):

1. Produce a variety of enzymes to control continuous cropping and root-knot nematodes.

2. It contains beneficial microbial flora, which can activate nitrogen in the air, release potassium nutrients and supplement soil organic matter.

3. The soil is soft and easy to cultivate, promoting the soil aggregate structure, releasing soil pores and promoting the growth of root groups. Keep the soil water and fertilizer.

Technology of granulating sheep manure with organic fertilizer granulator

Organic fertilizer manufacturing process by organic fertilizer granulator machine has many effects on crops. Not only can they provide nutrients needed for crop growth, but they can also enhance the stress resistance of crops.

1. Organic fertilizers contain organic matter needed for the growth of crops, a large number of elements, medium and trace elements, active microorganisms, active enzymes, etc., most of which can be directly used by crops. The action of microorganisms and active enzymes accelerates the decomposition and utilization of soil organic materials, which is beneficial to the full release of chemical fertilizers fixed by the soil, and at the same time improves the utilization rate of fertilizers.

2. There is a large amount of organic matter in the organic fertilizer, which increases the bulkiness of the frontal soil. Under the condition of high soil water content, it can ensure the normal function of crop root respiration. Under arid environmental conditions, the presence of agglomerates prevents the capillary channels of the soil from evaporating water outward, and can play a role in drought resistance and seedling protection. The organic fertilizer after fermentation contains a large amount of humic acid, amino acids, etc., which can provide drought resistance of crops. In the extreme cold weather conditions in the north, a large amount of organic fertilizer is applied in the greenhouse, which can play the role of brewing heat, heat absorption and heat preservation.

In the high-saline soil, applying organic fertilizer year after year is more effective than using chemical fertilizer alone. Related research shows that: organic fertilizer can improve soil desalination and salt tolerance.

In the production process of organic fertilizers, due to the action of microorganisms, a variety of physiologically active substances, such as vitamins, biotin, amino acids, humic acids, auxin antibiotics, etc., are synthesized. Some of these substances can stimulate crop growth, and some Can improve the disease resistance of crops, and some can enhance the lodging resistance of crops.

Organic fertilizers are complex in composition and rich in nutrients, can provide comprehensive nutrition for crops, and have unparalleled advantages over chemical fertilizers. Therefore, fruits and vegetables grown with organic fertilizers are sweet and mellow.

Measures to improve composting technology and quality of compost

Although the application of garbage compost can improve the soil and promote plant production, due to the composition of the garbage itself, the process is more professional in the fertilizer manufacturing process , which will also have a potential impact on the environment. The high cost of production, transportation and application, and poor economic benefits, restrict the application and development of compost. However, as a method of waste treatment and resource recovery, economic efficiency cannot be the only criterion for measuring, but to make it a promising method of garbage treatment, improving the composting process and improving the quality of composting are the main directions for future development.

Improvement of composting process

There is a long history of composting, and there are many technical processes. The treatment cost, treatment effect and compost quality of different process methods are different. Traditional anaerobic composting uses anaerobic microorganisms to complete the decomposition reaction. Air and compost are isolated, the temperature is low, the process is relatively simple, the nitrogen storage in the product is relatively large, but the composting cycle is too long, the odor is strong, and the decomposition is not Full substance. The modern composting process is basically aerobic composting through forced ventilation.This is because aerobic composting has a high temperature and effectively kills pathogenic bacteria.The matrix is completely decomposed, the composting cycle is short, and the odor is small. Etc.

How to sort and collect garbage, which sorting equipment is needed?

Composting is a treatment technology for organic components in garbage. The wastes such as Shikuai, metal, and glass not only affect the fermentation process of compost, but also affect the quality of compost. These substances must be sorted out and treated separately. At present, China’s urban domestic waste generally adopts a mixed collection method. Although the paper, plastic, etc. in the garbage are greatly reduced after multiple pick-ups by residents, scavengers, sanitation workers, etc., the garbage still contains some non-degradable substances such as metals and waste batteries , Waste lamps, etc. At present, in the process of composting, the method of mechanical combined with manual sorting is usually adopted. The mechanical sorting methods mainly include screening, wind sorting and magnetic sorting. Taking effective measures to promote the separation and collection of municipal solid waste in China is very necessary to save the cost of compost and improve the quality of compost.

Screening and cultivation of microorganisms, how to shorten the compost maturity cycle

Composting mainly uses microorganisms to degrade organic matter, and microorganisms are the main body of the composting process. The types and number of microorganisms in compost have an important influence on the fermentation time and fertilizer efficiency of compost. There are two main sources of microorganisms in composting. On the one hand, it comes from the composting material itself. On the other hand, special microorganisms are acclimated and cultivated to inoculate compost. These strains have the characteristics of strong activity, fast reproduction, and rapid decomposition of organic matter. They can accelerate the process of compost reaction, shorten the compost reaction time, and help reduce investment and land occupation.
