Composting machine and method for kitchen garbage

Abstract

The invention provides a composting machine and method for kitchen garbage. The composting machine comprises a hopper, a crusher, a screw conveyer, a fermentation tank and an oil-water separation tank, wherein the crusher is arranged below the hopper, a crushing cutter is arranged in the crusher, the screw conveyer is arranged at the downstream part of the crusher and is obliquely connected up to the fermentation tank by virtue of a conveying pipe, and the bottom of the screw conveyer is connected with the oil-water separator by a pipeline. When the composting machine is used, the solid garbage part in the kitchen garbage is processed into fertilizer in the fermentation tank and the fertilizer can be used for cultivating flowers and vegetables; the liquid garbage part in the kitchen garbage is subjected to oil-water separation and then is processed into a hydrotropic substance by a grease decomposing and deodorizing device and the hydrotropic substance is discharged together with water; therefore, the kitchen garbage can be prevented from being taken as the raw material of swill-cooked dirty oil. Due to use of an air deodorizing device and the grease decomposing and deodorizing device, the whole composting machine does not generate odor, thereby avoiding environment pollution.

Description

technical field [0001] The invention relates to a processing machine for composting kitchen waste, which is suitable for places such as unit canteens, restaurants, school canteens and the like that stably produce a large amount of kitchen waste. Background technique [0002] With the increasing degree of urbanization, garbage disposal has become an important factor restricting the healthy development of cities. For Chinese cities, due to the eating habits of Chinese people, there is a lot of kitchen waste and its composition is relatively mixed. In addition, it is difficult to implement domestic waste classification, and it is difficult to clean up kitchen waste in time. Kitchen waste is mixed with other living areas. In garbage, a little longer time will cause serious odor problems in the entire garbage bin, garbage collection vehicle and even the garbage dump, and the difficulty of sorting and processing garbage in the later stage will also increase sharply, which is the b...

Problems solved by technology

For Chinese cities, due to the eating habits of Chinese people, there is a lot of kitchen waste and its composition is relatively mixed. In addition, it is difficult to implement domestic waste classification, and it is difficult to clean up kitchen waste in time. Kitchen waste is mixed with other living areas. In garbage, a little longer time will cause serious odor problems in the entire garbage can, garbage collection vehicle and even the garbage dump, and the difficulty of sorting and processing garbage in the later stage will also increase sharply, which is the biggest problem in China's garbage disposal

[0003] Among them, canteens, restaurants, school canteens and other places produce a large amount of kitchen waste every day, which requires special treatment in links such as storage, regular cleaning, and transportation, which is time-consuming and laborious, and also affects the kitchen environment.
