Fermentation procedure and technological process of organic fertilizer production line
Fermentation process of organic fertilizer production line
1. Stacking technology
The ground was tamped before stacking, and then feces, peat, lebefeng second rot agent and other fermentation raw materials were mixed and piled in proportion.
2. Fermentation technology of stirring and turning pile
Materials are stacked in stacks, which can be arranged into parallel stacks. The cross-section shape of the stacks is usually triangular or trapezoidal, with a height of 1.5-2.0m and a width of 4-6m. The moisture content of the mixture is 55-65%.
The organic fertilizer production process is as follows:
Fermentation raw materials -- pretreatment -- mixing -- fermentation -- reconstitution -- granulation -- Packaging -- delivery
In the pretreatment process, it is necessary to crush the raw materials and adjust the particle size of the raw materials. The suitable particle size range is 12-60mm. Crushing and screening can increase the surface area of raw materials, facilitate microbial reproduction and improve the fermentation speed. After stacking, it can be turned over every 4-7 days, and can be stopped after 1 month to let it ripen naturally.
The organic fertilizer production line with an annual output of 5000 tons requires about 700m fermentation tank plant, 500m processing plant and 400m warehouse and office area. The organic fertilizer production plant cost is about 350000 to 500000 yuan.
