The whole process of organic manure production
The whole process of organic manure production can be simply divided into three processes: pretreatment, primary fermentation and post-treatment.
The whole process includes physical dehydration of fresh crop straw → crushing of dry raw materials → screening → mixing (the crop straw crushed by strains of fresh livestock and poultry manure is mixed in proportion) → composting and fermentation → temperature change observation → blowing and turning → moisture control → screening → finished products → packaging → warehousing.
1、 Pretreatment stage of organic manure production:
After the compost raw materials are transported to the storage yard, weighed by the scale, they are sent to the mixing and mixing device. The organic wastewater from the production and living in the plant can not be mixed, but water must be used. Then add organic fermentation complex bacteria (1-2kg per ton of raw material), and roughly mix the organic fertilizer according to the raw material composition (chicken manure: cassava residue or mushroom residue: straw = 6:2:2), and the moisture content is 60% - 65%, and the carbon nitrogen ratio is 20-30. When mixing ingredients in fertilizer production line, the brown sugar should be dissolved in water, and then organic fertilizer should be added to ferment biological bacteria, and then the diluent should be evenly sprinkled on the raw materials, and stirred with a mixer.
Note: composting materials should be treated several hours in advance and soaked with water. The water used for dilution of biological fermentation bacteria should be regarded as drinking water without disinfectant (such as bleaching powder).
2、 The first fermentation stage of organic manure production was as follows
The mixed raw materials are sent to the primary fermentation workshop by loader and piled into fermentation piles. At the same time, the piles are turned over in about 2 days, and the water and nutrients are added. The fermentation temperature is controlled at 50 ℃ ~ 65 ℃ (hot by hand), and aerobic fermentation is carried out. The one-time fermentation cycle of the production of organic fertilizer is 8 days. One pool of raw materials is put into one pool every day, and one pool of semi-finished products is produced. After the semi-finished products are discharged, they are ready to enter the next work Preface.
3、 After treatment stage of organic manure production:
The compost products were further screened, and the residue was treated according to the moisture content. After granulating, the screened materials are sent to the dryer for drying. Various additives are added according to the proportion (see Appendix 2 for additives). After mixing and mixing, the finished products are packed separately and put into storage for sale. The residue on the screen is returned to the crushing fertilizer production machine for reuse.
