Update time : 2021-11-19 Publisher:Tongda

Most of the organic matter of Chinese medicine residue is in line with organic fertilizer production, so any Chinese medicine residue can be used as raw material for organic fertilizer production and turn waste into treasure.  
 
How to use pharmaceutical residue to produce organic fertilizer?  The methods, steps and equipment required for the production of pesticide residue and organic fertilizer are as follows:  
 
1. Raw material crushing: the production of pharmaceutical residue, through the crusher crushed 10 ~ 50 mesh, crushing purpose is to avoid the fermentation tank in the process of ripening and stirring swirling leaves;  
 
2. Ingredients: Put the crushed pharmaceutical residues, livestock and poultry excrement, fermentation bacteria and water in the blender according to 55-70:15 ~ 25:2 ~ 4:10 ~ 30 and stir evenly;  
 
3. High temperature equipment fermentation: put the mixed materials in step 2 into high temperature fermenter, keep the temperature of 60 ~ 90℃, fermentation can be completed in 1~2 days;  
 
4. Aging: Place the materials fermented in step 3 in the aging chamber, keep the temperature at 60 ~ 70℃ under ventilation, and carry out secondary fermentation during aging for 3 ~ 6 days;  
 
5, Granulation: step 5 pharmaceutical residue and other raw materials, crushed again into the granulation machine, at the temperature of 50 ~ 60℃, maintain material moisture 8 ~ 15%, granulation;  
 
6, Drying: in the dryer, keep ventilation, control the temperature of 100 ~ 120℃, drying 20 ~ 40min, material moisture 3 ~ 5%;  
 
7. Cooling: Put the materials dried in step 7 into the cooling machine and cool to room temperature under ventilation;  
 
8. Finished product: The cooled material in Step 8 is screened by a screening machine, with the particle size remaining 1 ~ 4.5mm, and packaged.
