Production technology of chicken manure organic fertilizer

Chicken manure is a relatively high-quality organic fertilizer raw material. Its moisture content is 80% and that of straw is 10%. After composting, the moisture content of chicken manure can be reduced to 30% and the moisture of the initial material can be adjusted to about 60%. Then it can be calculated that the amount of backfill is 33% of chicken manure and the ratio of chicken manure to auxiliary materials is 3:1.
Straw, corn stalk, peanut stalk and other organic materials can be used as auxiliary materials according to local conditions. The chicken manure must be decomposed by the decomposing agent before application, and the parasitic eggs and infectious bacteria in the chicken manure can be inactivated and deodorized through the process of decomposing.

Process flow of chicken manure organic fertilizer production line
The complete equipment of general chicken manure organic fertilizer granule production line is mainly composed of fermentation system, crushing system, batching system, mixing system, granulation system, drying system, cooling system, screening system, coating system and finished product packaging system.

Secondly, the more complicated production process of chicken manure organic fertilizer granules is as follows: after fermentation, organic fertilizer raw materials (animal manure, domestic waste, dead branches and leaves, biogas residue, waste bacteria, etc.) enter the semi wet material crusher for crushing, and then add nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make the mineral elements meet the required standards, Then there is a mixer for mixing, and then the particles enter the granulation mechanism.

After coming out, they are dried and screened by the screening machine. The qualified products are packaged, and the unqualified products are returned to the granulation machine for granulation.
