Method for transforming food waste dregs fly maggots

Abstract

The invention discloses a method for transforming kitchen waste residue fly maggots, which belongs to the field of waste treatment. The method includes: S1, after sorting the kitchen waste to remove impurities, crushing and pulping, high-temperature cooking, and three-phase separation of the obtained oil phase, pulp residue and water phase; S2, inoculating the pulp residue with fly maggot eggs, culturing specific Time to obtain larvae and maggot dung; S3 to separate the insect feed. The method combines the equipment to form a production line that integrates feeding, inoculation, cultivation, and insect material separation. It can directly process the kitchen waste residue without adding auxiliary materials for conditioning, can realize mechanized operation, and has a positive role in promoting large-scale industrial applications. .

Description

technical field [0001] The invention belongs to the technical field of garbage disposal, and more particularly, relates to a process equipment and a method for the transformation of kitchen garbage residue and fly maggots. Background technique [0002] Food waste is the general term for food waste and kitchen waste. The former refers to the food residues produced by catering merchants (hotels, restaurants, canteens of enterprises and institutions, etc.) after food processing and food consumption, while the latter mainly refers to the food residues generated in the household life of residents, which are classified as urban domestic wastes. The main component of "wet garbage" is also one of the main components of urban organic solid waste. In 2020, my country's annual kitchen waste production will be about 128 million tons, with a daily production of 350,000 tons and a per capita daily production of 0.25kg. The market space for food waste treatment in my country is huge, and...

Problems solved by technology

[0014] Aiming at the above-mentioned lagging process of fly maggot treatment, the applicant has researched key problems for nearly 10 years and through a large number of experiments, developed a kitchen waste slag fly maggot conversion process equipment and method that can treat kitchen waste slag with multi-layer dynamic fly maggots. A production line integrating feeding, inoculation, cultivation, and insect material separation has been developed, which can be operated on a large scale; the fly maggot cultivation system, the core processing unit of the assembly line, operates in a sealed micro-negative pressure environment, and the odor is collected and processed, which can be directly Disposal of food waste residue without additional conditioning
