Organic fertilizer processing and production process: Livestock and poultry manure centralized treatment plants or organic fertilizer production enterprises will use dedicated vehicles to collect livestock and poultry manure from various farms at regular intervals to avoid secondary pollution to the road surface. The collected livestock and poultry manure will be directly sent to the fermentation area. After one fermentation, two aging and stacking. Firstly, it eliminates the odor of livestock and poultry manure. During a fermentation process, plant stems and leaves such as straw, plant leaves, and weed powder should be added in proportion. At the same time, fermentation strains should be added to decompose the coarse fibers, so that the particle size after crushing meets the particle size requirements of granulation production. Crush the fermented materials that have completed the secondary aging and stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add N, P, K, and other trace elements to the mixing and stirring system, start stirring, and transport the mixed materials to a disc granulation system. After being dried in a dryer, enter the cooling system and sieve the materials until they reach room temperature. The particles that meet the requirements enter the coating machine for coating and packaging. The particles that do not meet the requirements are crushed by the crusher and returned to the disc granulation system for further granulation. Through the above procedures, animal manure has become the main raw material for organic fertilizer and is directly sold in the sales market.
