Kitchen waste pretreatment system and method

Abstract

The invention provides a kitchen waste pretreatment system and method. The system comprises a receiving hopper, a paste making all-in-one machine, a light and heavy residue separation all-in-one machine, a heating oil-extracting device and a screw press, wherein the receiving hopper, the paste making all-in-one machine, the light and heavy residue separation all-in-one machine and the heating oil-extracting device are sequentially connected, the heating oil-extracting device is also connected with the paste making all-in-one machine, and the paste making all-in-one machine and the light and heavy residue separation all-in-one machine are further connected with the screw press respectively. The technological process changes kitchen waste into treasure. Low weight, harmless treatment and resource utilization of the kitchen waste are realized.

Description

technical field [0001] The application of the present invention relates to a food waste pretreatment system and method thereof, which can make food waste better harmless, reduce and recycle, and belong to the technical field of food waste treatment. Background technique [0002] Food waste treatment refers to a system that collects and treats slightly water and post-meal residues generated by restaurants, canteens, hotels and other catering industries through the food waste collection and transportation system, and realizes harmlessness, reduction and resource utilization. thriving industry. The so-called food waste pretreatment is to separate the non-biologically treatable substances such as domestic waste mixed in the food waste. So that the food waste can be better harmless, reduced and recycled. Since this industry has only been developed for more than ten years, many production processes are immature at present. At present, there are mainly the following process schem...

AI Technical Summary

Problems solved by technology

Most of the domestic processing modes rely on manual sorting, with heavy sorting workload, low sorting efficiency and poor sorting effect

Due to the late start of waste classification in my country and poor classification awareness, a large amount of domestic waste is mixed in the kitchen waste, and the equipment cannot work after the kitchen waste is mixed with other garbage, resulting in a high failure rate of production equipment

A large amount of organic matter was lost due to screening in the first step of pretreatment

In addition to the need for more manual participation in the pulping process, a large amount of clean water must be added in the production process, resulting in an increase in the amount of waste disposal, which directly affects the economic and economic benefits of the enterprise
