The design of chicken manure organic fertilizer pellet fermentation production process design includes:
1.Efficient compound bacteria and its propagation technology;
2. advanced raw material allocation technology and biological fermentation system;
3. the best special fertilizer formula technology (can flexibly design the best combination of product formula based on local soil and crop characteristics);
4. Reasonable secondary pollution (exhaust gas and depression) control technology;
5. Design and manufacturing technology of organic fertilizer production line equipment.
The more complicated process of chicken manure organic fertilizer production line is as follows: organic fertilizer raw materials (animal manure, domestic waste, dead leaves, biogas residues, waste bacteria, etc.) are fermented into a semi-wet material grinder for crushing, and then nitrogen is added. Phosphorus and potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements reach the required standard, and then have a mixer to stir, and then enter the fertilizer granulator machine to get granules, after drying, screened by a sieving machine, qualified products are packaged, and unqualified returned to the granulator for granulation.
Among them, the reasonable mix of fineness of raw materials is very important for the organic fertilizer production line.
The fineness of the whole raw material should be matched as follows: about 100% to 60% of the raw materials account for about 30% to 40%, 60% to 1.00㎜ diameter raw materials account for about 35%, small particles with a diameter of 1.00-2.00㎜ 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 ultra-high proportion of high-fineness materials is prone to problems such as excessively large particles and irregular particles.
