Description

Method for reliably processing residual food in canteen Technical Field The invention relates to a technology for processing leftovers, in particular to a method for reliably processing leftovers of a canteen. Background The residual food in the canteen usually comprises leftovers and leftovers, wherein the leftovers in the canteen are mainly meat and vegetables and are auxiliary, so that the leftovers in the canteen belong to high-protein substances, are easy to rot, and can cause serious environmental pollution after being decomposed. The existing residual food in the canteen is usually collected in a spoiled water bucket and is supplied to a pig farm to serve as pig feed, but the residual food in the canteen usually contains a large amount of bacteria, so that pigs can be infected with certain diseases, and people can be endangered if eating the pork infected with the diseases. In addition, the collected residual food in the ranched barrel emits a very unpleasant smell, which pollutes the environment. In addition, people use the kitchen waste processor to process leftovers, and the principle is that the leftovers are crushed and the crushed leftovers are discharged into a sewer. The disadvantage is that the load of the sewage treatment plant is increased and the sewage pipe network is blocked.
