Production process of organic fertilizer
The production process of organic fertilizer in this project is as
follows: Fermentation: The livestock and poultry excrement (dry
excrement) is transported to the fermentation tank by the transport
vehicle, and is put into the fermentation tank with humic acid,
chelating agent, amino acid and other raw materials in a
quantitative proportion of --. At the same time, biological
bacteria are added to convert the animal excrement into organic
fertilizer. This project mainly uses pig dung, cow dung and sheep
dung as raw materials, uses high-temperature aerobic composting
technology for fermentation, then after ripening treatment, finally
through processing and granulation, to make efficient and green
refined organic fertilizer. The organic fertilizer production
process of this project mainly includes raw material pretreatment,
composting, secondary fermentation, screening, granulation,
cooling, packaging and other processes, as shown in Figure 5-1.
Among them, powdered organic fertilizer has no granulation process
and is directly made into powdered products. The raw materials in
the early stage shall be pre mixed after fermentation. According to
the organic fertilizer formula, Add a certain amount of N/PK and
trace elements.
