Processing technology of livestock manure organic fertilizer

The technological process of livestock manure organic fertilizer production line is as follows: raw material treatment → harmless treatment → mixing ingredients → granulation → cooling screening → metering and sealing → finished products warehousing.

Raw material treatment, that is, separate water and fertilizer for some feces with high moisture content;

Harmless treatment, that is to add fermentation bacteria into the manure, through high temperature fermentation, kill the harmful bacteria and eggs in the manure, and thoroughly decompose the fertilizer;

Mixed ingredients, that is, according to the local soil structure, adding relevant materials to improve the fertility of animal manure, such as humic acid, nitrogen, phosphorus, potassium fertilizer, to improve the fertility and adaptability of organic fertilizer;

Granulation, fertilizer granulation machine is to crush, mix and granulate organic fertilizer according to the use requirements of organic fertilizer. Fertilizer granulation machine can choose disc granulator, double roller granulator, organic fertilizer granulator, rotary drum granulator, flat die pelleting machine, and ring die pelleting machine. 

After the pretreated livestock and poultry manure is fermented in the mixing and fermentation device, the appropriate amount of nitrogen, phosphorus, potassium and other elements are added according to a certain proportion to make the microelements meet the production standard of organic fertilizer. After the processing processes of mixing, crushing, shaping, granulation, drying and packaging, the livestock and poultry manure is processed into organic fertilizer with high fertilizer efficiency, convenient transportation, safe use and affordable price.
