Kitchen waste treatment system

Technical Field

The utility model belongs to the refuse handling installation field, in particular to kitchen garbage processing system.

Background

The kitchen waste is a domestic waste formed in the process of domestic consumption of residents, is extremely easy to rot and deteriorate, emits foul smell and spreads bacteria and viruses. The kitchen waste comprises rice and flour food residues, vegetables, animal and vegetable oil, meat and bones and the like, and mainly comprises starch, cellulose, protein, lipid and inorganic salt from the chemical composition. The kitchen waste is an important pollution source of urban environment, and the direct utilization and improper treatment can cause the spread of pathogenic bacteria and environmental infection, and can threaten the normal life and body health of people.

Therefore, how to reasonably dispose the kitchen waste is a problem which needs to be solved urgently at present.

Disclosure of Invention

The utility model aims at providing a kitchen garbage processing system utilizes this system to handle kitchen garbage, and not only simple process is reasonable, and the treatment effect is good moreover, the treatment effeciency is high.
