Production method and system for treating kitchen waste through hermetia illucens

Abstract

The invention discloses a production method and system for treating kitchen waste through hermetia illucens. The system comprises a plurality of breeding boxes which are arranged in a stacking manner,a kitchen waste pre-treatment device, a culture material mixing device, an automatic feeding device and an automatic screening device, wherein the kitchen waste pre-treatment device, the culture material mixing device, the automatic feeding device and the automatic screening device are sequentially arranged based on the processes; the culture material mixing device is connected to the automatic feeding device; the automatic feeding is capable of automatically synchronously feeding culture materials into the plurality of breeding boxes; the automatic screening device is used for collecting larva and excrement of the hermetia illucens in the breeding boxes by class. According to the production system, all processes, such as the process of preparing the culture materials of the hermetia illucens, the process of feeding and the process of recovering and classifying treatment, can be carried out in a scaled, intensive and mechanical automatic manner, so that the labor consumption can be decreased, and the breeding efficiency can be obviously improved.

Description

technical field [0001] The invention relates to a production method and system for treating kitchen waste by using black soldier flies. Background technique [0002] Food waste generally refers to raw materials and finished products or residues needed in daily life, such as leftovers, fruit peels, eggshells, etc. In recent years, the output of kitchen waste has shown an obvious growth trend, of which kitchen waste accounts for about 10%-20% of the total waste. With such a huge volume and continuous production every day, the aftermath treatment of food waste is put on the agenda. [0003] The traditional treatment methods of food waste mainly include two kinds of incineration and landfill. Incineration is easy to produce harmful gases, while landfill is easy to cause soil and groundwater pollution. Moreover, due to the high water content of food waste, it will form harmful leachate under the action of high-pressure microorganisms when it is directly mixed with other waste a...

Problems solved by technology

Its disadvantage is that it cannot automatically feed and separate black soldier fly larvae and insect droppings in batches, and the degree of mechanization is low
