1. Raw materials: organic fertilizer production requires raw materials, such as chicken manure, pig manure, cow dung, duck manure, sugar dregs, distiller's grains, sludge, medicine dregs, sugar dregs, etc.
2. Fermentation: The purpose of aerobic fermentation is to fully decompose, sterilize, deodorize and remove water. After fermentation, the moisture content of raw materials does not exceed 35%, and it is odorless and tasteless.
3. Crushing + sieving: crush the fermented material, sieve out the incompletely crushed material, and crush again.
4. Mixing: Add nitrogen, phosphorus, potassium and other trace elements in proportion, and stir evenly. The powdered organic fertilizer can be packaged directly after further drying.
5. Granulation: choose the appropriate granulation equipment according to your own situation. Common organic fertilizer granulators include: roller extrusion granulator, drum granulator, disc granulator, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, each granulator has its own production characteristics, and the fertilizer granulator machine price varies.
6. Drying: Low-temperature hot air (≦65°C) dries the moisture to below 30%.
7. Cooling: After drying, the temperature is slightly higher, and then natural air is introduced through the cooler for cooling.
8. Screening: Screen the particles, and the large particles are sent to the pulverizer through the belt conveyor for re-crushing.
9. Coating machine: add brightener and anti-caking agent to make the particles more smooth.
10. Automatic packaging + conveyor belt.
