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.

China has a vast territory and rich raw material resources for organic fertilizer machine. It is understood that the final urine excreted by a pig in one year combined with litter can produce 2000-2500kg of high-quality organic fertilizer, which is enough for one mu of land to use fertilizer throughout the year. Ingredients, content of more than 6%, organic content of more than 35%, are higher than national standards.

Investment in the construction of an organic fertilizer plant has also become an important way for investors to make profits. At the same time, it has also driven the development of organic fertilizer manufacturing process. Many places have begun to build professional equipment and production lines for organic fertilizer production. The government also encourages agricultural and animal husbandry enterprises to increase investment in organic fertilizer equipment. 

Judging from the current situation, in the future, organic fertilizer will certainly occupy an important place in the fertilizer market, and the development of the organic fertilizer manufacturing process will also be unlimited.

There are three configurations of organic fertilizer equipment:

High configuration: chicken manure dehydrator, fermentation stacker, semi-wet material crusher, horizontal mixer, fertilizer granulator machine, dryer, cooler, roller screening machine, film coating machine, packaging equipment, belt conveyor, etc.

Medium configuration: semi-humid material crusher, horizontal mixer, granulator, dryer, cooler, roller screener, packaging equipment, belt conveyor, etc.

Low configuration: semi-wet material pulverizer, horizontal mixer, granulator / drum screening machine, packaging equipment.

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.

 How to ferment the raw materials in the organic fertilizer manufacturing process is a prerequisite. Compost fermentation generally adopts aerobic fermentation technology, which uses the metabolic activities of microorganisms to decompose the organic substances in the materials, so that the materials of the composted organic fertilizer are stable and harmless.

At present, most organic fertilizer production enterprises adopt the fermentation process of trough stacking. The main equipment is an organic fertilizer turning machine. Other fermentation methods such as flat stacking fermentation, sealed warehouse fermentation and tower fermentation are also used. The compost fermentation process is to manually control the compost materials under the appropriate temperature, humidity and air content conditions, and use the selected composite microorganisms (bacteria, actinomycetes, yeast, etc.) to degrade the organic matter in the materials and generate high temperature to kill Pathogens, insect eggs and weed seeds in solid wastes such as dead animal poultry manure, plant straws, etc., are fermented and rotted to make them stable and harmless. Finally, it is processed into commercial fertilizer through organic fertilizer equipment.

The organic fertilizer after fermentation is dark brown, its texture is soft and uniform, and it is rich in organic matter, nitrogen, phosphorus, potassium and other trace elements, various nutrients, biologically active substances, and beneficial microorganisms. It has mature soil and cultivated fields. The role of fertilizers and soil improvement. The compost fermentation process is a complex physical, chemical and biological change process. It mainly degrades organic matter under the aerobic conditions by the action of aerobic microorganisms. The factors that affect the compost fermentation cycle and the quality of the composted organic fertilizer mainly include carbon to nitrogen ratio and organic matter content. Moisture content, temperature, pH value and ventilation oxygen supply and other 6 aspects.

Composition of compound fertilizer processing equipment:

BB fertilizer (formula fertilizer) complete equipment is mainly composed of automatic batching and packaging host, control box, conveyor, sewing machine, air pump, motor, etc. The equipment specifications are diverse, and the hourly output is 3-6T, 7-9T, 10-14T, 15-18T, 20-24T, 25-30T, etc. According to the mixed materials, it is divided into 2~8 parts.

The operation of a double roller extrusion granulator for compound fertilizer production is a complex but necessary process in the production of high-quality fertilizer. The granulator comprises two smooth, parallel rollers rotating at different speeds in opposite directions. The material is put into the machine, and the rollers compress and produce minute particles out of the substance. The combination of the two rollers enables a high rate of granulation even with tiny amounts of material, ensuring that the fertilizer produced is of optimal size, shape, and uniformity.

Organic fertilizer manufacturing process refer to commercial organic fertilizers that do not contain specific fertilizer effects and are processed and deodorized by high-temperature treatment using livestock waste, straw, agricultural by-products and solid waste processed in food processing, organic waste, and urban sludge. It has the advantages of improving the efficiency of farm soil to improve fertilizer efficiency, but also has its own characteristics:

1.High organic matter content, generally greater than 30%, and some as high as 60%.

2.The harmless standard is high, and the refined organic fertilizer has undergone 4-5 days of high temperature treatment during the production process, which can effectively kill the pathogenic microorganisms, pests and weed seeds in the raw materials, making the fertilizer hygienic standard significantly better than farm fertilizer To meet the standards issued by the Ministry.

3.Low cost, refined organic fertilizer raw materials mostly use agricultural wastes and by-products, with a wide range of sources, usually using simple high-temperature rapid processing technology to evaporate a large amount of water in the raw materials, rapid deodorization, rapid dehydration, low energy consumption, production The cost is low and economical.

4.Refined organic fertilizers mainly provide organic matter and a small amount of nutrients, which has the advantage of rich organic matter. However, due to the low nutrient content (about 6%), it usually can not meet the needs of crop growth. Generally, it needs to be used in conjunction with inorganic fertilizers.

In the organic fertilizers manufacturing process, how to granulate the raw materials after fermentation is a key factor that determines whether commercial fertilizers can enter the market and circulate. Generally, the following granulation methods are adopted.

(1) Agglomeration granulation. It is under the action of rotation, vibration, stirring, etc. to make the wet powder in motion agglomerate. Or use fluidized bed to make dry powder and granules get cohesion by supplying spray liquid (adhesive) to grow into proper granules.
 

(2) Extrusion granulation. It is a method that uses mechanical processing such as extrusion, roller extrusion or pressing to make dry powder or wet powder containing binder into a cylindrical, spherical or tablet shape.
 

(3) Crushing granulation. It is to crush massive materials into granules of appropriate size.
 

(4) Melt granulation. It is a method of granulation by cooling and hardening molten liquid.
 

(5) Spray granulation. It is a method of directly granulating solids in liquid after concentration.
 

(6) Crystallization and granulation method in the liquid phase. It is a method of agglomerating into spherical particles by liquid bridging agent and stirring while the materials are crystallized in the liquid phase.

This technology is widely used in the pharmaceutical industry. Because the shape of the particles is spherical, it is also called the spherical crystallization granulation method, referred to as the spherulite granulation method. The spherulite granules are pure material particles, which have good fluidity, filling property and compression moldability. In recent years, the technology has been successfully prepared. That is, in the process of spherulite crystals, polymer copolymer precipitation is added to prepare slow-release, quick-release, enteric, stomach-soluble pellets, floating hollow pellets, biodegradable microcapsules, etc. Recently, it has been successfully applied to the preparation of sustained-release pellets.

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.

In China’s agricultural production, in order to increase the yield of crops, people will not hesitate to dump a large amount of chemical fertilizers (inorganic chemical fertilizers) into the farmland, and the use of nitrogen fertilizer, urea, and compound fertilizer composed of nitrogen, phosphorus, and potassium is increasing, and the concentration The higher. Although this has maintained a certain effect of increasing output, year after year, the consequences are extremely serious, the main performance is as follows:

So what the benefits of the organic fertilizer manufacturing process are?

First, the soil is compacted and solid, resulting in poor soil porosity and decreasing organic matter content, which has caused many biological groups to lose space for survival in the soil and ultimately reduced soil fertility.

Second, due to soil compaction, the soil’s water storage capacity is decreasing, and the lack of groundwater has seriously affected agricultural production.

Third, due to the soil compaction, the biological population is reduced, and the farmers ’friends are striving to increase the yield of the land, so that the amount and concentration of chemical fertilizers continue to increase, resulting in the decreasing utilization of nitrogen, phosphorus, and potassium, only reaching 30% to 40% According to the calculation of the consumption, the loss will reach 30 billion to 40 billion yuan.

Fourth, in addition to wasting losses, a large amount of chemical fertilizers remaining in the soil continue to penetrate deep underground to form a large amount of nitrate and other compounds, causing serious pollution of groundwater, and on the other hand, it is released into the atmosphere as nitrogen oxides, making The ozone layer becomes thinner, causing ultraviolet light to affect human health and the growth of crops, and the ecological environment is severely affected.

Fifth, the use of large amounts of chemical fertilizers has reduced the quality and nutritional value of various crops. Take trace elements as an example. For half a century, the content of trace elements in some crops has dropped by about 20%, and the commodity rate of crops has declined, which seriously affects the interests of farmers and consumers and the export of crops.

In short, agricultural production cannot be at the expense of resources and the environment. It must combine high yield with high quality, low consumption with ecological security, and take the road of sustainable development of agricultural production. Otherwise, for such a long period of time, the natural ecology will be seriously unbalanced, and it will be the human beings that are damaged, and the consequences will be very serious. The use of scientific methods and the combination of organic and inorganic fertilizers to produce and process organic fertilizers using animal manure as raw materials, and nitrogen, phosphorus and potassium as auxiliary fertilizers is one of the most correct ways for modern agriculture.
