Although the livestock and poultry breeding industry has developed well in recent years, its risk is relatively high. Once some livestock and poultry epidemics occur, it is easy to cause the farmers to lose their money. At the same time, the livestock and poultry feces produced in the breeding process need to be treated with a large amount of manpower and material resources, which seriously increases the cost of the farmers. On the one hand, the production of antagonistic bio organic fertilizer by using livestock and poultry manure can reduce the cost of livestock and poultry manure treatment by farmers, and on the other hand, the antagonistic bio organic fertilizer produced will bring great economic benefits to farmers and increase their income.

The process of producing organic fertilizer by fermentation of livestock and poultry manure with organic fertilizer equipment

Adding antagonistic microorganisms for secondary fermentation: after decomposing livestock and poultry feces and fermenting high-temperature virus killing bacteria, it is necessary to add an appropriate amount of antagonistic microorganisms, inorganic nutrients, humic acid nitrogen fertilizer synergists, phosphorus and potassium chelators, and then let the livestock and poultry feces decompose for secondary fermentation. In this process, antagonistic biological bacteria will be contained in the decomposed products, and at the same time, a high-temperature environment will be formed again to kill virus and bacteria for the second time, making the harmless treatment more thorough. In addition, the secondary fermentation process can also quickly deodorize, so that the fertilizer will not produce irritating taste.

Drying treatment of organic fertilizer equipment: after the secondary fermentation is completed, the fermentation products need to be dried, mainly by using solar greenhouse to create a high-temperature environment (above 60 ℃), so that the fermentation products can be quickly dehydrated and the water content can be reduced to about 15%. There is no technical content in this process. It should be noted that the drying treatment cannot make the water content of the fermentation product too low, otherwise the granulation process in the later stage will be affected.

Crushing and granulation of organic fertilizer equipment: after drying, the fermentation product is in a solid state. Therefore, it needs to be crushed, and the fermentation product is crushed by machinery. After the pulverization is completed, the granulator is used for granulation, so that the pulverized material becomes fine particles with uniform size.

Finished products: after the completion of crushing and granulation, low-temperature dehydration is carried out. This link is different from drying treatment. It requires a high-temperature environment. It needs to keep the particles in a low-temperature environment, so that the water retained in them can be slowly evaporated. After the low-temperature dehydration treatment, the antagonistic bio organic fertilizer can be obtained and sold in bags.
