[0002] Kitchen waste is the household waste generated by residents in the process of daily consumption. It is the main type of food waste. It includes food processing scraps (kitchen waste) and edible residues (swill) generated by food markets, residential areas, school canteens, large star-rated hotels, medium and large catering service companies, commercial plazas, airports, bus stations and high-speed rail stations. Its composition is complex, mainly a mixture of oil, water, fruit peels, vegetables, rice, fish, meat, bones, waste tableware, plastic, paper towels and other substances. It is characterized by being extremely easy to rot, emit a foul odor, and spread bacteria and viruses.

[0003] At present, when food waste is treated, it is generally necessary to manually sort and classify the waste. The classification of untreated waste causes the treatment personnel to smell toxic gases for a long time, which causes damage to the body. In addition, waste treatment requires multiple processing steps, and each process is an independent processing equipment, so that it needs to be transported to the next processing process equipment after being processed in the previous process, and continuous processing operations cannot be carried out. The processing efficiency is low, and the odor will spread in the equipment room during the transportation of the waste. Therefore, an integrated pretreatment equipment for food waste is proposed.
