Kitchen waste, commonly known as swill, is the main type of food waste, including food residues generated by families, schools, and the catering industry, etc. Its composition is complex, mainly a mixture of oil, water, vegetables, rice, noodles, meat, and other substances. The quantity of kitchen waste in China is extremely large and shows a rapid upward trend. Kitchen waste is a type of domestic waste, and a pneumatic vacuum conveying device can be used to convey kitchen waste.

[0003] According to the Chinese patent with the publication number CN204453823U, a feeding device for vacuum conveying of kitchen waste is disclosed. While the kitchen waste is sent into the storage bin through vacuum conveying, a metal sintered filter screen filter, a fine dust removal device, and an activated carbon air filter are used for air filtration in sequence to prevent the spread of pathogenic bacteria and pathogenic microorganisms and control the surrounding air quality.

[0004] Regarding the above-mentioned disclosed patent content, a liquid spraying pipe is provided to spray disinfectant through the liquid spraying pipe, so as to disinfect and clean the inner wall of the feed hopper. Although the sprayed disinfectant can flow in the feed hopper, since some garbage impurities still adhere to the inner wall of the feed hopper, it will block the flow of the disinfectant, making the disinfectant only able to disinfect some areas of the feed hopper. At the same time, since some garbage always adheres to the inner wall of the feed hopper and is difficult to be cleaned, bacteria may breed continuously in this part of the garbage, thus reducing the cleaning efficiency of the garbage on the inner wall of the feed hopper and affecting the disinfection efficiency of the feed hopper.
