In the production of powdered organic fertilizer, it mainly adsorbs dust floating debris floating in the air. When the livestock and poultry manure is harmlessly treated, the aerobic strip stack fermentation is generally adopted. That is, the general stacking fermentation, in the fermentation need to pay attention to, to avoid wind and rain, reduce organic matter. Therefore, before fermentation, it is necessary to build a rain shelter and build a fermentation tank.
The following is an introduction to the animal manure composting process:
1. Ratio of raw materials per ton: 500kg of cow manure 300kg of pig manure 200kg of strains 50g of strains (cow manure and pig manure can also be replaced by other livestock and poultry manure) accessories: When the humidity of livestock and poultry manure is large, appropriate materials with lower water content such as straw, rice husks, and cake meal can be added to reduce the moisture content of fermented materials. Alternatively, you can use a solid-liquid separator machine.
2. Strip stack: According to the above raw material ratio, the strip pile is carried out as needed. The length of the strip pile is not limited, the width is 2 meters, and the height is about 1 meter. In the strip stacking, the material needs to be stacked evenly layer by layer. According to the size of each fecal treatment, choose the appropriate thrower width. The following figure shows a animal manure composting machine with a lifting type, which can mobilize the height of the pile and shorten the return speed of the pile.
3. Add strains: Expand the strains and residue in a ratio of 1:5 (the purpose of this is to dilute the strains and spread them evenly. For example, 1kg of strains can be mixed with 5kg of wheat bran or rice husk powder). Generally, 1kg of bacteria can ferment 10 to 20 tons of manure and straw, and in the case of a large amount of fermentation, it can be evenly mixed with the help of a fertilizer blending equipment, and sprinkled on the surface of the strip pile according to the number of strip piles.
4. Turning the pile fermentation: use the commercial composting systems to flip the strip pile. The temperature rises above 55 °C, turn the pile every 1 to 2 days, and after 10 to 15 days of fermentation at 55 °C, the strip pile can be put away. (The purpose of the pile is to evaporate the water, oxygen enters the inside of the pile, and the bacteria enter the inside of the pile and reproduce and ferment rapidly)
5. Crushing: Fermented materials can not be sold directly as commodities, this is because long-term stacking will cause agglomeration and other phenomena. At this time, the remaining large pieces of material need to be finely crushed by the compost grinder, and the powdered organic fertilizer is obtained after crushing. (Pre-fermentation, in order to accelerate the fermentation process, the excipient can be added to the crusher for crushing)
6. Screening: In order to improve the selling phase, the powdered organic fertilizer is re-screened to obtain a uniform powdered material before it can be packaged. After following the above steps, it will become pure powder organic fertilizer after being screened by the fertilizer screening machine.
7. Packaging: The powdered organic fertilizer can be directly stored and sold after being packaged by the fertilizer bagging machine.
After these 7 steps, it is possible to produce powdered organic fertilizer in the process of composting animal waste. Of course, if you want to make powdered organic fertilizer that meets the standards, you also need to determine the organic substance composition of fermented manure and straw fertilizer, add nitrogen, phosphorus and potassium content, and also need to adjust the proportion of straw and other auxiliary materials to determine the various content formulas of organic fertilizer.
