There are a lot of diseases and insect pests in cow dung. Without fermentation and sterilization, these diseases and insect pests will be directly brought into the soil, which will lead to the occurrence of diseases and insect pests, crop yield reduction and even death. organic fertilizer production process

To avoid these problems, cow dung must be fermented. So, how to ferment cow dung into pollution-free organic fertilizer?

First of all: to solve the problem of high humidity of cow dung, it is necessary to reduce the water content of cow dung. The cost of using separate sewage harmless treatment equipment is high, the technology is difficult, and the treatment capacity is small (the cycle in the fermentation tank is long, and the old one has entered the fermentation tank before the new one comes out). organic fertilizer production plant cost is low. Therefore, we can add wheat straw, corn straw, rice straw, rice husk powder, peanut seedling powder, furfural residue, soybean cake, oil and other auxiliary materials with low water content. On the one hand, it can reduce the water content of cow manure, on the other hand, it can increase the content of organic matter after fermentation composting. Straw, husk bran, cake, dregs and other materials are crushed by semi wet material crusher. After the crusher is even, straw and other auxiliary materials are mixed with cow dung urine at the ratio of 3:1 (high moisture content) or 1:1 (low moisture content) to start fermentation.

The technological process of organic fertilizer production line can be divided into raw material pretreatment, aerobic fermentation and fertilizer granulation. The pretreatment of raw materials includes solid-liquid separation, grinding of auxiliary materials and adjustment of water content, carbon nitrogen ratio and pH value of raw materials. The aerobic fermentation process includes compost, ventilation and other measures, which can supplement oxygen, control temperature, release water and restore porosity.
