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.

The agricultural machinery market has great potential for development, and of course is full of various competitions and challenges.
