Organic Fertilizer Production Process
- The ratio of raw materials per ton
500 kg of cow dung + 300 kg of duck manure + 200 kg of bacteria residue + 100 g of RW bacteria.
(The above cow dung and duck manure can be replaced by other livestock manure)
- The pile
According to the above ratio of raw materials, the piles are piled according to the needs. The length of the pile is not limited, the width is 2 meters and the height is 1 meter. When the pile is piled, it is necessary to stack the materials evenly layer by layer.
- Add bacteria
The bacterial agent is expanded by a ratio of 1:5, and after being uniformly mixed, it is sprinkled on the surface of the pile according to the number of piles.
- Stirring fermentation
Stir the strip pile evenly with a compost turner. After the temperature rises to 60 degrees or more, turn it over every 4-5 days, and ferment the mixture at 60 degrees or more for 15 days.
- Screening processing
According to the above steps, after fermentation, after sieving and deep processing, it becomes pure organic fertilizer.
- Granulation
The fermented pure organic fertilizer is granulated. The granulator, the disc granulator, the extrusion granulator, the extrusion and throwing machine, etc. are selected according to different raw materials.
- Drying, cooling, packaging
The freshly prepared granules have a relatively large moisture content, and the moisture needs to be dried to less than 20% of the organic fertilizer standard, and the dried granular organic fertilizer is directly packaged after being cooled by a cooling machine.
