Equipment and method for treating kitchen waste by using black soldier flies

Abstract

The invention discloses equipment and a method for treating kitchen waste by using black soldier flies. The equipment comprises a draining conveyor, a first dehydrator, a spiral conveyor, a crusher, a second dehydrator, a feeding pump, breeding boxes, a discharge conveyor, a screening machine and a dryer. The draining conveyor is successively connected to the first dehydrator, the spiral conveyor, the crusher, the second dehydrator and an inlet of the feeding pump; an outlet of the feeding pump separately feeds treated kitchen waste into a feed inlet of at least one breeding box, and a discharge port of the at least one breeding box is successively connected to the discharge conveyor, the screening machine and the dryer. The method comprises the following steps of: feeding black soldier fly larvae which are 4 days old with kitchen waste for 6 days by using the equipment;, then successively screening and drying the black soldier fly larvae, and quantitatively adding the kitchen waste by using the equipment of treating kitchen waste by using black soldier flies. Therefore, on the one hand, the handling capacity of the kitchen waste is maximized, and on the other hand, the black soldier fly larvae eat the kitchen waste thoroughly.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a device and method for treating kitchen waste by using black soldier flies. Background technique [0002] Black Soldier Fly (Hermetia illucens L.), a saprophytic Soldier Fly insect, can complete a generation in 35 days in a suitable environment. A pair of black soldier flies can lay nearly 1,000 eggs in a lifetime. From eggs to mature larvae, the individual growth is nearly 4,000 times. It is a kind of soldier fly insect that can be produced as a resource. It has important uses in the treatment of livestock manure, the production of animal protein feed and the production of biodiesel. However, the current black soldier fly breeding method is relatively extensive, basically in the stage of local farming, without a complete set of mechanical equipment or complete process design, and completely relying on manual experience and hard work to control the breeding process, whic...

Problems solved by technology

The degree of automation of the above-mentioned bioprocessor is not high, and the stirring process is likely to cause the death of adults. The pretreatment of the raw material and the feeding of black soldier flies are not considered as a whole, and the automatic operation of the whole process is not realized. The processing capacity of the equipment is small, and it cannot reach the industrial level. The need for large-scale applications
