Livestock and manure organic fertilizer manufacturing process
generally includes: raw material selection (chicken manure and other animal dung) → dry sterilization → ingredient mixing → granulation → cooling screening → metering sealing → finished product storage.
Livestock and poultry manure is a relatively high quality organic fertilizer containing pure nitrogen, phosphorus (P2O5) and potassium (K2O) of about 1.63%, 1.54%, and 0.085%. The manure of livestock and poultry must be decomposed by the decomposing agent before application, and the parasites and eggs in the feces of the livestock and poultry, as well as some infectious bacteria, can be inactivated and deodorized by the process of decomposing.
The production process of organic fertilizer for livestock and poultry manure is as follows: organic fertilizer raw materials (animal manure, domestic garbage, dead branches and rotten leaves, biogas residue, waste bacteria, etc.) are fermented and then enter a semi-wet material pulverizer for pulverization, and then add NPK, etc. The elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the mineral elements contained meet the required standards, then stir with a mixer, then enter the fertilizer granulator machine
, and then dry and pass through the sieve. The machine is screened, the qualified products are packaged, and the unqualified return granulator is used for granulation.
Among them, the reasonable combination of the fineness of the raw materials is crucial for the organic fertilizer production process. According to the experience of environmental protection, the fineness of the whole raw materials should be matched as follows: 100-60 mesh raw materials account for about 30%-40%, 60 mesh to diameter 1.00mm raw materials account for about 35%, and diameter 1.00-2.00mm small particles. About 25% - 30%, the higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the use of super-proportioned high-fineness materials is prone to problems such as excessive particles and irregular particles due to excessive adhesion.
Livestock and poultry manure organic fertilizer production characteristics:
1. Advanced raw material blending technology and biological fermentation system; 2. Efficient compound strain and its expansion technology; 3. Reasonable secondary pollution (exhaust gas and odor) control technology; 4. Optimal special fertilizer formula technology (The flexibility to design the best combination of product formulations based on local soil and crop characteristics).
