Description

Technical Field

[0001] The utility model relates to the technical field of resource processing of restaurant kitchen waste, in particular to an integrated machine for crushing and sorting restaurant kitchen waste. Background Art

[0002] At present, most of the food waste treatment methods are to collect it through transfer stations and then transport it to landfills for centralized disposal. The problem is that if mixed landfill is adopted, the waste composition is complex, easy to rot, stink and release gases that are harmful to human health. It is also easy to breed mosquitoes and spread diseases, and the leachate will pollute water and soil and damage the environment. Another treatment method is incineration. The problem is that due to the high water content and low calorific value of food waste, if mixed waste incineration is adopted, it is easy to increase the production of dioxins, so incineration is not an effective treatment method.

[0003] At present, relatively complex processes utilize coarse crushing, mixing, and extrusion processing, but these processes are primitive processing methods and cannot effectively separate food waste (organic matter) and other waste (inorganic matter) in food waste. Utility Model Content
