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;
