How much investment is needed for small cattle manure organic fertilizer
Small scale cattle manure organic manure production plant only needs to invest in a composting turnover machine, and the organic fertilizer production plant cost is about 20000 yuan.
How does the equipment of organic fertilizer production line say that cow dung is transformed into organic fertilizer? Let's tell you in detail:
Organic fertilizer production machine manufacturers tell you how to make organic fertilizer from cow manure
1. Firstly, in the organic fertilizer production line, the cow dung should be dried or dried to make its moisture content less than 85%. Then, straw powder should be added, and the ratio of cattle to cattle should be 7:3, so that the carbon ratio of raw material (cow dung) and auxiliary material (straw powder) should be controlled at 23 ~ 28 and 52% ~ 68% respectively. Finally, organic fertilizer fermentation maturity agent should be added
2. After the raw materials, auxiliary materials and bacterial agents are mixed and stirred, they can be piled up for fermentation. The requirement of upper stacking is to stack the mixture into trapezoidal stacks with bottom width of 1.8 ~ 3 meters, upper width of 0.8 ~ 1 meters, and height of 1 ~ 1.5 meters. The interval between the strips and stacks is 0.5 meters. After stacking, the temperature will rise to above 60 degrees in 24 ~ 48 hours, and start to turn over after keeping the temperature for 48 hours
3. The organic fertilizer production process equipment must be evenly and thoroughly turned over. The low-level special materials should be turned into the middle and upper parts of the pile as far as possible, so as to fully decompose. After the first turning, the compost should be turned over once a week. However, when the temperature exceeds 70 ℃, it must be turned over immediately, otherwise, a large number of beneficial microorganisms and fermentation bacteria will be killed, which is not conducive to fermentation and maturity
