Organic fertilizer production process:
- The ratio of raw materials per ton is 500 kg of cow dung + 300 kg of duck dung + 200 kg of bacterial residue + 100 g of RW bacterial agent. (The above cow dung and duck dung can be replaced by other livestock and poultry dung)
- The strip pile shall be piled according to the above raw material ratio. The length of the strip pile is not limited, the width is 2 meters, and the height is 1 meter. When stacking, the materials need to be evenly stacked layer by layer.
- Add the fungus agent to enlarge the volume of the fungus residue in the ratio of 1:5, mix it evenly, and sprinkle it on the surface of the pile according to the number of piles.
- Stir and ferment. Use a mixer to mix the piles evenly. After the temperature rises above 60 degrees, turn the piles every 4-5 days. After 15 days of fermentation at 60°C, put the piles away.
- Screening and processing. After fermentation according to the above steps, it will become pure organic fertilizer after screening and deep processing.
- Granulation: granulate the fermented pure organic fertilizer. According to different raw materials, select granulator, disc granulator, extrusion granulator, extrusion and throwing ball integrated machine, etc.
- Drying, cooling, and packaging The moisture content of the freshly-made granules is relatively large, and the moisture needs to be dried to below 20% of the organic fertilizer standard, and the dried granular organic fertilizer is directly packaged after being cooled by a cooler.
