With the development of modern animal husbandry, the dairy industry has greatly improved and enriched the material life of the Chinese people. According to incomplete statistics, the current stock of dairy cow farming in Sichuan Province has reached around 140000 heads, and dairy cow farming is gradually developing towards intensification and scale. There are more than 130 farming communities with a scale of 50 to 1500 cows in the province, and more than 3000 small-scale cattle farms with a scale of 10 to 49 cows. Dairy cow farming has become a new growth point for rural economy and an effective way to increase farmers' income. However, at the same time, the pollution caused by cow farming to the environment is becoming increasingly serious. Cow manure has become one of the main sources of non-point source pollution in rural and suburban areas. The control of cow manure pollution has become a highly concerned and urgent task for the government and breeding owners.

The new organic fertilizer granulator is used to granulate various organic substances after fermentation, breaking through the conventional organic fertilizer granulation process. Before granulation, the raw materials do not need to be dried or crushed, and can be directly mixed to produce spherical particles, saving a lot of energy. The produced particles are spherical. High organic content allows for pure organic granulation. By utilizing the centrifugal force of organic particles, they can be embedded and grow together, and there is no need to add binders during granulation. The particles are solid and can be sieved after granulation, reducing drying energy consumption. The organic matter after fermentation does not need to be dried, and the moisture content of the raw material can be around 20% -40%.

The small-scale cow manure organic fertilizer production line has low energy consumption, small footprint, no odor in the operating environment, zero pollution, good ventilation, and deodorization in only 1-2 days. The small rabbit manure organic fertilizer production line has a compact structure and advanced technology. It uses harmless live bacterial preparations to treat livestock and poultry manure, and undergoes biological fermentation under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill bacteria and insect eggs, detoxify and deodorize, purify the environment, and achieve harmless, resource utilization, and industrialization. The energy consumption is low, and the product quality is stable.
