Intensive production system for treating kitchen waste through hermetia illucens breeding

Abstract

The invention relates an intensive production system for treating kitchen waste through hermetia illucens breeding, which is layered and partitioned. The system is divided into a kitchen waste distribution chamber and an odor purification device on the ground layer as well as a feeding room and a separation operation device on the underground layer. The homogenized kitchen waste materials are input into a suspension type feeding trolley. The upper end of the suspension type feeding trolley is connected to a suspension type feeding trolley track, and movable material ramming is conducted on a breeding frame. A plurality of layers of breeding boxes are horizontally placed on the breeding frame, and hermetia illucens larvae are pre-added into the boxes. After ramming and feeding for a plurality of days, the fecula and the imagoes are simply collected and transported to a separation operation device. The odor in the feeding room is collected under negative pressure and is discharged after reaching the standard through the odor purification device. According to the intensive production system, multiple links such as material conveying, material ramming, collecting, screening, drying, metering and packaging and deodorization can be automatically completed, labor and land are saved, the working efficiency is high, the produced dry hermetia illucens and fecula can be recycled, and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and relates to an intensive production system for treating kitchen waste by breeding black soldier flies. Background technique [0002] With the rapid economic development and urbanization process, the amount of kitchen waste is increasing year by year, and the resulting pollution problems are also becoming more and more serious. Food waste is rich in a large amount of organic matter, and the recycling of solid organic matter has become an important factor in the profitability of the project. In the traditional process, solid organic matter is ground into a slurry, which is injected into an anaerobic tank for digestion and biogas production. Due to the complex composition of waste, problems such as mechanical wear, pipe blockage and even anaerobic acidification will occur in grinding, pumping, dehydration and other links. In addition, the generated biogas needs to be purified and...

AI Technical Summary

Problems solved by technology

Odor gas is directly discharged without treatment and easily pollutes the environment; but if the odor of the entire breeding factory is collected and processed, the energy consumption of the exhaust fan is huge, and the cost of deodorization is high
