System for conducting kitchen waste resourceful treatment through black soldier flies

Abstract

The invention discloses a system for conducting kitchen waste resourceful treatment through black soldier flies. The system comprises a sorting machine, a magnetic separator, a crushing machine, a hydrocyclone, a presser and a fermentation machine. The sorting machine is used for conducting preliminary crushing on kitchen waste and screening out large-sized metal and plastic products in the kitchen waste, and a first material is obtained; the magnetic separator is used for removing the rest of metal in the first material, and a second material is obtained; the crushing machine is used for crushing the second material; the hydrocyclone is used for separating thick liquid mixed by the crushed second material and water into a third material and ceramic and glass fragments large in specific gravity; the presser is used for pressing the third material, and the third material is separated into a fourth material and an oil-water mixture; and the fermentation machine is used for fermenting thefourth material into fodder of the black solder flies. By means of the system, the kitchen waste is subjected to impurity removing, crushing and dehydration and fermentation treatment, the fodder used for feeding the black solder flies is made, and resourceful treatment of the kitchen waste is achieved.

Description

technical field [0001] The invention relates to the technical field of waste treatment and reuse, in particular to a system for resource-processing kitchen waste by using black soldier flies. Background technique [0002] Kitchen waste mainly refers to the organic waste generated in the catering industry, canteens and family cooking and dining, and generally includes leftovers, kitchen raw material scraps, melon peel and fruit scraps, etc. Food waste is rich in nutrients and high in water content, and it is easy to breed bacteria and cause decay and deterioration, resulting in a pungent odor. According to statistics, the annual output of urban kitchen waste in my country has exceeded 60 million tons, which has become the "enemy" of urban development. Solving the problem of kitchen waste has become a social issue of public concern. [0003] Black soldier flies are widely used in the resource utilization of kitchen waste. However, in addition to leftovers, kitchen raw materia...

AI Technical Summary

Problems solved by technology

[0003] Black soldier flies are widely used in the resource utilization of kitchen waste. However, in addition to leftovers, kitchen raw material scraps, melon skin and fruit scraps and other organic matters, kitchen waste also contains a large number of packaging bags, beverages, etc. Inorganic substances such as bottles, metal products, porcelain, glass products, etc. These inorganic substances are not conducive to the breeding of black soldier flies, so they have become technical difficulties in the utilization of black soldier flies for resource treatment of kitchen waste
