Technology of producing powdery fertilizer by pig manure Organic fertilizer production line

In the powdered pig manure fertilizer production process, pig manure is firstly collected, mixed with hay and rotten silage to make compost and let it ferment. Fermentation process is divided into: composting, heating, tossing, odorless, loose, composting. When composting, 80% of livestock and poultry manure, 20% of straw, are crushed and mixed. The mixing ratio of straw and manure can be determined according to the moisture content of manure. Generally, 65% of the water content is required for fermentation, that is to say, when the hands are squeezed into a ball, the fingers can see the water, but there is no water dripping, and the solution can be released as soon as the hands are released. Then add corn flour or rice bran and strain, the function of corn flour is to increase the sugar content for strain fermentation, so that the multi-dimensional complex enzyme bacteria quickly take the absolute advantage. Add the prepared mixture into the mixer for mixing, and make sure that the mixture is uniform, transparent and free of lumps.

Production technology of organic fertilizer machine for powdered pig manure
1. Rump fermentation
Use the compost windrow turner to turner the strip stack. When the temperature rises above 55 ℃, pile up once every 1-2 days. After fermentation at 55 ℃ for 10-15 days, put up the pile. (the purpose of turning over the reactor is to promote water evaporation, oxygen entering the reactor, bacteria entering the reactor and rapid propagation and fermentation)
2. Material crushing
Fermented materials can not be sold directly as commodities, because long-term stacking will cause caking and other phenomena. At this time, the bulk material left by the screen needs to be finely crushed by the high humidity material crusher, and the powdered organic fertilizer will be obtained after crushing. (for the early stage fermentation of the powder fertilizer production line, in order to speed up the fermentation process, the auxiliary materials can be added into the pulverizer for crushing)
3. Screening and grading
In order to improve the sales phase, the powdered organic fertilizer can be re screened and the uniform powdered material can be packed. After operating according to the above steps, the pure powder organic fertilizer will be formed after being screened by the roller screen.
4. Packaging of finished products.
The powdered organic fertilizer can be directly put into storage and sold after being packaged by automatic packing scale.
