Larvae and nutrient separating system and separating method for hermetia illucens cultivation

Abstract

The invention discloses a larvae and nutrient separating system for hermetia illucens cultivation. The larvae and nutrient separating system comprises a first box body, a second box body, a regulatingdevice and a rotary collecting device, wherein the first box body is used for holding a larvae and nutrient mixture for hermetia illucens cultivation; the second box body is used for holding collected hermetia illucens larvae; the regulating device includes at least one rotatable cage body, and the at least one cage body is arranged in the first box body, and is used for forming and regulating temperature or light intensity received within a region range in the first box body so as to directionally drive the hermetia illucens larvae; and the rotary collecting device includes at least one rotatable collecting assembly; the at least one collecting assembly includes at least three collecting rods of which the end parts are concurrent; when the at least three collecting rods are located in afirst position, the hermetia illucens larvae are driven by the regulating device into the at least three collecting rods; and when the at least three collecting rods are located in a second position,the hermetia illucens larvae in the at least three collecting rods are released into the second box body. According to the larvae and nutrient separating system, by utilizing the habits of the hermetia illucens larvae to avoid light and heat, the hermetia illucens larvae are driven to crawl independently to separate from nutrients; and moreover, the crawling distance is short, the separating efficiency is high, the work efficiency is improved, and the cultivation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a system for separating insect material for black soldier fly breeding. Background technique [0002] Black soldier fly is a saprophytic Soldier Fly insect, which can feed on poultry manure and household garbage, etc., and produce high-value animal protein feed. It is currently widely used in the treatment of chicken manure, pig manure and kitchen waste thing. [0003] However, in the black soldier fly breeding process, it is necessary to separate the black soldier fly larvae that have reached the finished product specification from the treatment residue, so that the black soldier fly larvae can be used for feed processing, etc., and the residue can be used to prepare fertilizers. The current separation method is mainly through traditional manual screening and machine screening. The former is inefficient and labor-intensive, and the separation effect of the latter is not...

AI Technical Summary

Problems solved by technology

The current separation method is mainly through the traditional manual screening separation and machine screening method, the former is inefficient and labor intensive, and the separation effect of the latter is not ideal, especially when the humidity of the nutrient is slightly high, the separation effect is not good
