Description

Kitchen garbage solid-liquid separation device

Technical Field

The invention relates to a waste treatment device, in particular to a kitchen waste solid-liquid separation device.

Background

The restaurant industry generates a large amount of kitchen waste, which is commonly referred to as swill, every day. At present, most of general hotels, restaurants and canteens do not adopt a method of directly dumping swill, but are sold to individual pig raising households at low price, and the pig raising households simply heat the collected swill to be used as pig feed. Since swill contains a large amount of oil and animal protein, the meat quality of pigs eating the feed for a long time is reduced, and as the food chain is prolonged, some toxins can accumulate and finally transfer to human beings. Along with the improvement of environmental protection consciousness of people, the current more correct swill treatment mode is to transport swill to special place for centralized treatment after collecting the swill by the restaurant, but the swill needs certain condition to store, and the swill has increased the way of bacterial transmission in transit again. The kitchen waste is subjected to solid-liquid separation treatment in time so as to be beneficial to collection and recycling of the kitchen waste, so that the kitchen waste is a better way for solving the problem, and no ideal device for carrying out the solid-liquid separation on the kitchen waste is available in the market at present.
