Technical Field

The invention relates to the technical field of kitchen waste treatment equipment, in particular to a kitchen waste deoiling, desalting and sterilizing process and device.

Background

Aerobic fermentation and anaerobic fermentation are two processes for resourceful treatment of the kitchen waste, and both rely on biological agents to decompose organic components in the waste. Most of biological agents are sensitive to grease and salt, especially antibiotics or other bacteria, so that survival of the biological agents in the garbage treatment equipment is threatened greatly, and the recycling effect of the kitchen garbage is influenced. In the existing kitchen waste recycling treatment process, in the pretreatment process of contacting the waste with the biological agent, the kitchen waste is generally crushed, extruded and dehydrated, and then directly enters a fermentation device to be further decomposed by the biological agent. Only a small part of grease and salt in the garbage is discharged along with the dehydration process, and the majority of grease and salt directly enter the fermentation process. In addition, organic matter components in the kitchen waste contain a large amount of nutrients, a large amount of bacteria can be bred due to untimely treatment, and the bacteria seriously threaten the survival of the biological agent after entering a fermentation process.
