To produce organic fertilizer, it is first necessary to collect waste materials such as livestock manure, clean, stir, and remove impurities. After the preliminary preparation work is completed, the fermentation process is entered. The personnel should pay attention to the material for secondary stacking fermentation, stacking 15 to 20 days the temperature is reduced to about 40 degrees, and the bactericides with phosphorus, potassium, nitrogen fixation and underground pest control functions are evenly added to the fermented materials in a ratio of 1 to 500.

Next, the organic fertilizer can be stacked and fermented for 7 days to reach the standard of bio-organic fertilizer, and the fermented bio-organic fertilizer is screened into the warehouse. The processed functional pure bio-organic fertilizer was granulated. According to different raw materials to choose organic fertilizer granulator, disc granulator, extrusion granulator, extrusion ball throwing machine and so on.

Generally, the moisture content of freshly made particles is relatively large, and the water needs to be dried to less than 20% of the organic fertilizer standard, and the biological organic fertilizer needs to be selected at low temperature (temperature below 80 degrees) when selecting the dryer, and the dried granular organic fertilizer is packaged directly after cooling by the cooling machine, which can bring good economic benefits.
