Automatic hermetia illucens breeding system with kitchen waste as base material

Abstract

The invention discloses an automatic hermetia illucens breeding system with kitchen waste as a base material. The system mainly comprises a temporary storage tank, an automatic feeding trolley, a plurality of groups of breeding frames, breeding boxes, a hermetia illucens material screening device, and a metering and packing machine. The automatic feeding trolley moves back and forth between the temporary storage tank and the breeding frames to transport compost; the multiple groups of breeding frames are arranged in parallel; the multiple layers of breeding boxes are horizontally placed on the breeding frames; a second screw conveyor is mounted at the bottom in each breeding frame; a third screw conveyor is mounted outside each breeding frame; the hermetia illucens material screening device is connected with the third screw conveyors; and the metering and packing machine is connected with the hermetia illucens material screening device. According to the automatic hermetia illucens breeding system with the kitchen waste as the base material, the kitchen waste can be treated on a large scale, hermetia illucens can be automatically fed, materials are simply collected, and fecula and adults can be efficiently separated. Produced dry hermetia illucens and fecula can be recycled, and economic benefits are achieved; and the system is intensive, labor is saved, working efficiency is improved, and large-scale popularization can be achieved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment and relates to an automatic breeding system for black soldier flies based on kitchen waste. 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 reused, and th...

Problems solved by technology

[0004] At present, there are two ways to breed black soldier flies. One is mainly artificial breeding. The workers work between simple breeding racks, and the environment is foul-smelling and inefficient, so it cannot be promoted on a large scale; the other is mechanization and automation equipment. However, the structure of the existing equipment is complex, the process is cumbersome, the cost is high, and it is not easy to maintain and maintain
