There are two steps to process commercial organic fertilizer in organic fertilizer production line
: early fermentation and treatment part and deep processing granulation part.
The production of organic fertilizer by pig manure fermentation needs good (consumption) oxygen fermentation. Therefore, in the process of operation, it is necessary to increase the oxygen supply measures, so as to mix well, turn frequently and ventilate. Otherwise, it will lead to anaerobic fermentation and odor, affecting the fertilizer effect. The fermentation is complete. Generally, after 48 hours of pig manure accumulation, the temperature rises to 50-60 ℃, and it can reach above 65 ℃ in the third day. Under this high temperature, it can be overturned once by the organic fertilizer production machine fermentation dumper of Huaqiang Heavy Industry in general, there will be two times of high temperature above 65 ℃ in the fermentation process. The fermentation can be completed by overturning twice, and the fermentation can be completed in about a week. The material was dark brown, and the temperature began to drop to room temperature, indicating that the fermentation was completed.
Fertilizer granulation processing is a systematic project. Around the core of granulation forming, there are crushing, batching, mixing and other processes before, drying, screening, cooling and other processes after.
The complete set of organic fertilizer production line includes fermentation equipment, pulverizer, mixer, granulator machine for fertilizer
, dryer, cooler, screening machine, coating machine and packaging machine, as well as conveyor for material transportation between the equipment. Such a full set of equipment configuration needs two or three hundred thousand, but the whole production line only needs five or six workers to complete the production operation and realize automatic production.
