Organic fertilizer production process

About the 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 pile of bars should be proportioned according to the above raw materials. The stacking is carried out according to the needs, the length of the stack 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 bacteria agent. Increase the volume of the fungus residue with a 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 blender to mix the piles evenly. After the temperature rises above 60 degrees, turn the pile every 4-5 days. After 15 days of fermentation at 60 degrees, put the piles away.
5. Screening and processing. After fermentation according to the above steps, it becomes pure organic fertilizer after sieving and deep processing.
6. Pelletizing: Pellet 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 freshly manufactured granules have a relatively high moisture content, and the moisture needs to be dried to below 20% of the organic fertilizer standard. The dried granular organic fertilizer is directly packaged after being cooled by a cooler.
