Description
Technical Field
[0001] The utility model relates to the technical field of screening machines, in particular to a black soldier fly maggot screening machine. Background Art
[0002] Screening machine is a mechanical equipment that uses the relative movement between bulk material and screen surface to allow some particles to pass through the screen holes and separate the material into different grades according to particle size.
[0003] When using a screening machine to screen black soldier fly larvae in the organic solid waste insect bioconversion industry, since the existing screening machine usually has only one filter screen, it can only perform one screening process at a time, resulting in incomplete screening of material residue, black soldier flies and larvae, and reduced screening efficiency. At the same time, the material has a high moisture content, and the material residue is easily adhered to the black soldier flies and larvae, making it difficult to separate the adhered material residue from the black soldier flies and larvae during screening, which also causes incomplete screening and reduced screening efficiency. In reality, the method of shading nets and plastic films is usually used for processing, but this easily leads to low efficiency, long time, low insect separation rate, and high labor intensity. In order to reduce the moisture content of the material and facilitate screening, the breeding time is usually extended, which not only increases the breeding cost and reduces the conversion rate, but also when the insects are raised to mature state, the black soldier fly shells become thicker and the protein content decreases, which is not conducive to back-end utilization.
