Example Embodiment

[0028] Example 1

[0029] This embodiment is a method for separating yellow mealworms. Taking advantage of the photophobicity of yellow mealworms, a light area and a dark area are set in the cultivation container of yellow mealworms, and a green light source is used to irradiate the yellow mealworms to make the living insects crawl into the dark area. Manure and feed remain in the light zone, thereby separating live insects.

[0030] The green light source can be a bulb with a power of 5-11W, preferably 8W.

[0031] The experimental study on the separation method of the yellow mealworms was carried out under different wavelengths of light sources, and it was concluded that when the light source wavelengths were 570-600nm and 400-480nm, the yellow mealworms did not have any anaphobic reaction to the light source. When it is between 490-550nm, the yellow mealworm will show aversion to light (that is, stay away from the light source). The specific results are: (1) Blue light: under the...

Example Embodiment

[0032] Example 2

[0033] The method for separating yellow mealworms described in Example 1 is applied to a large-scale cultured yellow mealworm separation device, and its structure is as follows figure 1 As shown, it includes a culture box 1, a baffle 2 and a green light source 3. A movable baffle is set in the middle of the culture box. When the baffle is closed, the baffle divides the space in the culture box into an unconnected light zone 4 and a dark bottom. Zone 5, the top of the light zone is provided with a green light source.

[0034] The baffle is a plug-in structure, the top or side of the culture box is provided with a socket (not shown in the figure), and the baffle is vertically inserted into the culture box from the socket. When you need to open the baffle, just pull the baffle out directly from the socket.

[0035] When the yellow mealworm separation device is used, in the daily breeding of yellow mealworms, the baffle is closed, the yellow mealworms are cultivated i...

Example Embodiment

[0036] Example 3

[0037] This embodiment is a yellow mealworm separation device. Compared with Embodiment 2, the difference lies in that the baffle is a hinged structure, and the upper or middle part of the baffle is connected to the breeding tank through a hinged shaft. When it is necessary to open the baffle, just turn the hinge shaft to turn the baffle over, and the light area and dark area under the baffle are connected.

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...
