Pre-treatment

The organic fertilizer production line uses livestock and poultry manure as the main raw material. Because of its high moisture content, it is necessary to add a certain proportion of weathered coal, oil shale, straw, and edible fungus waste base material with low moisture content as a conditioning agent, and then add a certain proportion of bacteria Seed, mix and adjust to a suitable moisture content (45%-55%) and C/N ratio (15-30), mix and stir evenly, and stack them for fermentation.

Tumbling and stirring

The fertilizer production machine performs stirring, aeration, and fermentation of the material pile; after the temperature rises to 50 to 65 ℃, it can effectively kill the bacteria and eggs in the raw materials and evaporate a large amount of water.
Temperature control

regularly inspect the temperature, moisture and permeability of the fermented material pile every day. During the fermentation process, due to the action of microorganisms, the organic matter content, moisture, temperature, C/N ratio, and pH value in the pile will change, so it is necessary to check and adjust regularly. 
The turning of the organic fertilizer production line generally follows the principle of "time to unequal temperature, temperature to unequal time", that is, the low temperature stage of the early fermentation should be turned regularly; the middle fermentation high temperature stage should be turned in time when the temperature reaches about 65℃ , So that the stack temperature will not exceed 70 ℃.

Post-fermentation treatment

After high-temperature fermentation, the material is basically harmless, and most of the soluble organic matter has been converted. The biochemical speed gradually slows down. It can be piled up and cooked to promote the stabilization of organic matter and save the fermentation space. The second compost completes the complete degradation of organic matter and transforms it into stable humus. The maturity of compost fermentation can be assessed from physical, chemical, biochemical and other indicators according to the self-inspection ability.
