Kitchen waste integrated processing method and equipment thereof

Abstract

The invention discloses a kitchen waste integrated processing method and equipment thereof. According to the method, kitchen waste is naturally filtered for the first time, and naturally filtered-out liquid is removed; the kitchen waste with high viscosity is squeezed and filtered through a screw for the second time, the liquid capable of being separated out through squeezing is separated out, and waste residues are obtained; the obtained waste residues and basal feed with adsorbability are mixed to form a mixture containing oil and water, and animal feed is obtained after drying and forming; and the naturally filtered-out liquid and the liquid separated out through squeezing are subjected to oil and water separation. The equipment comprises a machine frame, a pre-processing system and an oil and water separation system, wherein the pre-processing system and the oil and water separation system are arranged on the machine frame. The equipment is compact and ingenious in structure and small in size. When the kitchen waste is rapidly converted into the animal feed, high-degree dehydration before forming is not needed, proper oil and water in the residues are reserved, nutrition of the animal feed is improved, and excessive consumption of resources caused by high-degree dehydration is avoided. The processing equipment is simplified, the process steps are reduced, the process period is shortened, the cost is low, and the conversion efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment engineering, and relates to a kitchen garbage treatment system, in particular to an integrated treatment method and equipment for kitchen garbage, which separates kitchen garbage from oil and water and converts kitchen garbage into animals at the same time. feed. Background technique [0002] With the continuous development of my country's economy and the continuous improvement of people's living standards, the catering industry in various cities has also entered a stage of rapid development, but the accompanying domestic waste and kitchen waste have seriously polluted the urban environment and sanitation. bring great harm to the life and health of the people. [0003] With the rapid development of the economy and the continuous improvement of people's living standards, the urban catering industry has become increasingly prosperous, resulting in an unprecedented increase in the amount of...

Problems solved by technology

Food waste is a potential resource that has been neglected for a long time. Compared with other municipal solid waste, food waste has high water content, high organic matter content, high oil content and salt content, and less toxic and harmful substances (such as heavy metals, etc.) , but the rate of rot and deterioration is fast, and it is easy to grow bacteria, especially in high temperature seasons, it is easy to rot and deteriorate, which leads to the rapid and massive reproduction of pathogenic microorganisms, mycotoxins and other harmful substances

Therefore, if not handled properly, it will cause adverse effects on the environment and human health

[0005] At present, there are many food waste treatment technologies at home and abroad, mainly to separate food waste from oil and water. If the separated food waste is to be used, it usually needs a lot of biochemical treatment to transform a small amount of products. The treatment process The steps are cumbersome, the equipment is complicated, the production cycle is long, the input cost is high, and the basic laboratory research stage, the industrialization process is basically in a state of loss; the simple processing and molding of the meal dregs after multiple filtrations also requires a lot of energy consumption to remove Excessive liquid components in the meal dregs can reach the material viscosity required for molding; due to the special composition of the dregs, the rate of decay and deterioration is fast, the processing steps are complicated, and the longer the cycle, the higher the cost to prevent it from decay and deterioration; therefore, how to It is particularly important to develop simple and efficient equipment for recycling food waste into resources
