Separation method and device for yellow mealworms

Abstract

The invention discloses a separation method and device for yellow mealworms. The separation method includes the steps that due to the photophobism of the yellow mealworms, a light area and a dark area are arranged in a breeding container of the yellow mealworms, green light sources are adopted to irradiate the yellow mealworms, live insects creep to the dark area, dead insects, excrement and feed are left in the light area, and therefore the live insects are separated. The device comprises a breeding box, a baffle and the green light sources. The movable baffle is arranged in the middle of the breeding box, and when the baffle is closed, the space in the breeding box is divided by the baffle into the light area and the dark area, wherein the bottom of the light area and the bottom of the dark area are not communicated; the green light sources are arranged at the top of the light area. Or the device comprises a conveying belt, brush rollers, an upper cover, the green light sources, a live-insect collecting mechanism and a waste collecting mechanism. The brush rollers are arranged on the two sides of the conveying belt respectively, the upper cover is arranged above the brush rollers, the green light sources are arranged on the inner surface of the upper cover, the live-insect collecting mechanism is arranged on the outer side of the brush rollers, and the waste collecting mechanism is arranged at the tail end of the conveying belt. The separation method and device are simple in principle, good in yellow-mealworm separation effect and high in separation efficiency.

Description

technical field

[0001] The invention relates to the technical field of insect breeding, in particular to a method and device for separating Tenebrio molitor. Background technique

[0002] Tenebrio molitor, commonly known as mealworm, is rich in protein, minerals and 17 kinds of amino acids, etc. It is one of the most ideal insects for artificial breeding. Tenebrio molitor larvae need to be separated from dead worms, live worms, feces, feed, etc. during the 4-5 days of feeding. The method currently used is still the traditional manual selection, but manual selection requires experienced breeders and is only suitable for separating a small amount of pupae. Although this method is simple and easy to implement, it is time-consuming and labor-intensive, which is not conducive to the development of large-scale breeding. . At present, there are also some separation machinery and equipment in China, such as the utility model patent with the application number 201220105437.8, which...
