A farm with 300 cows has a daily manure output of nearly 10 tons, which is about 3,650 tons a year. The discharge of manure from farms has always been a problem of environmental pollution.

It costs millions to buy pollution treatment equipment, which is not cost-effective for farm owners. Cow dung cannot be directly applied to the land without fermentation and decomposition. Direct application will cause serious problems such as burning seedlings and dead trees. With the promotion and popularization of the policy of replacing chemical fertilizers with organic fertilizers. Processing cow dung into organic fertilizer not only solves the problem of pollution from livestock and poultry manure emissions, but also can be sold on the market to increase economic income. So, how can cow dung be fermented and decomposed into pollution-free organic fertilizer?

First of all, dehydration equipment is needed to reduce the water content in cow dung, so that the water content in cow dung can be maintained at 60%, or wheat bran, corn stalks, rice straw, rice husk powder and other auxiliary materials can be added to cow dung to reduce the water content of cow dung and increase the organic matter content after fermentation and composting.

Next, fermentation is required. During the fermentation process, the compost needs to be turned continuously. The organic fertilizer fermentation turning machine can be used for fermentation, which can save a lot of labor and time. Insert several thermometers on the fermentation pile to observe and measure the temperature of the cow dung compost at any time. When the temperature of the cow dung fermentation pile rises above 50℃, start turning the pile with a trough-type compost turning machine, turning the pile once every 2-3 days to ensure that the temperature of the pile is between 60℃ and 65℃. After fermentation, if there is agglomeration, it can be crushed with a crushing equipment, which can reduce the hardness of the cow dung and make the powder of the cow dung organic fertilizer more delicate. It is also convenient for subsequent granulation to ensure the quality of the finished product.
