[0002] Animal husbandry is an important part of agriculture. It covers the raising and breeding of a variety of animals, including but not limited to poultry, livestock, and aquatic products. In the early stages of economic development, animal husbandry often existed as a sideline to crop production, but with the development of the economy, it has become a relatively independent industry in some regions.

[0003] With the development of the breeding industry in recent years, the treatment of farm manure and sewage has become an important environmental protection issue, posing a threat to the sustainable development of modern agriculture and social economy, the safety of the agricultural ecological environment, and the quality safety of agricultural products. Livestock and poultry excrement generally contains more organic matter and trace elements. As the raw material of biological organic fertilizer, it can provide sufficient nutritional needs for the growth of crops.

[0004] During the processing process, the existing solid-liquid dry-wet separation device generally separates the solid and liquid first, and then squeezes the solid once to reduce the water content. However, some highly viscous feces are squeezed once, and only a small part of its water content is squeezed out, thereby reducing the efficiency of dry-wet separation. Utility Model Content
