[0002] In recent years, with the rapid development of animal husbandry, large-scale livestock and poultry farms are expanding, and the number of livestock and poultry is increasing year by year. Due to factors such as feeding management, nutrition level, disease prevention and control technology, and immune stress response, the mortality rate of livestock and poultry is high, and the amount of dead animals is increasing year by year. If the dead animal carcasses are disposed of at will, not only will it affect environmental sanitation and cause environmental pollution, but also the spread of viruses and bacteria will spread and even mutate due to environmental influences, causing new animal epidemics and the possibility of mutual transmission of zoonoses. Moreover, it is extremely easy to endanger the safety of animal food, seriously endangering human and animal health and the sustainable and stable development of social and economic construction.

[0003] Currently, dead and diseased animals are mainly disposed of by incineration, chemical processing, burial, or other physical, chemical, and biological methods to completely eliminate the pathogens they carry and achieve the purpose of eliminating disease factors and protecting human and animal health and safety. Chemical processing is the most advanced processing technology because of its high efficiency and thoroughness. Chemical processing mainly includes the following steps: 1. Pretreatment of dead and diseased animals and related animal products by crushing. 2. Transporting the dead and diseased animals and related animal products or crushed products into a high-temperature and high-pressure sterilization container. 3. Heating and drying the generated hot steam and discharging it after waste gas treatment. 4. Transmitting the animal carcass residues generated by heating and drying to a squeezing system for processing.

[0004] During the squeezing process of the animal carcass residues in the squeezing system, the crude oil produced often contains oil residues produced by incomplete oil squeezing. For this, the existing technology method deposits the squeezed oil in a crude oil pool to obtain pure crude oil, and the oil residues are deposited in the crude oil pool, which are then manually salvaged. However, the salvaged oil residues have a high oil content and cannot be sold as qualified by-products; secondly, the crude oil in the oil residues is not fully utilized, resulting in resource waste.
