Detailed description of organic fertilizer production technology and process

Organic fertilizer production process:

  1. 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)
  2. 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.
  3. 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.
  4. 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.
  5. Screening and processing. After fermentation according to the above steps, it will become pure organic fertilizer after screening and deep processing.
  6. 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.
  7. 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.
