Problems solved by technology

However, in practical applications, the noise is relatively large, and the separation of Tenebrio molitor needs to be screened through the vibrating screen many times, and the separation effect of the screened dead insects and live insects is also poor.

Embodiment 1

[0029] A kind of Tenebrio molitor separation method of the present embodiment utilizes the photophobia of Tenebrio molitor to set light zone and dark zone in the culture container of Tenebrio molitor, adopt green light source to irradiate Tenebrio molitor, live worm crawls to dark zone, dead worm, Feces and feed remain in the light zone, thereby separating live insects.

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

[0031] Experimental research was carried out on the separation method of Tenebrio molitor, and Tenebrio molitor was tested under light sources of different wavelengths. It was found that when the wavelength of the light source was 570-600nm and 400-480nm, Tenebrio molitor did not have any light-aversion reaction to the light source. When the wavelength is between 490-550nm, Tenebrio molitor will show aversion to light (that is, stay away from the light source), and the specific results are: (1) Blue light: Under the acti...

Embodiment 2

[0033] The Tenebrio molitor separation method described in embodiment 1 is applied to the Tenebrio molitor separation device of large-scale cultivation, its structure is as follows figure 1 Shown, comprise breeding box 1, baffle plate 2 and green light source 3, the middle part of breeding box is provided with movable baffle plate, when baffle plate is closed, baffle plate divides the space in the breeding box into light zone 4 and dark zone that the bottom is not connected. Zone 5, the top of the light zone is equipped with a green light source.

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

[0035] When the Tenebrio molitor separation device is used, in the daily cultivation of Tenebrio molitor, the baffle is closed, the Tenebr...

Embodiment 3

[0037] The present embodiment is a Tenebrio molitor separation device. Compared with Embodiment 2, the difference is that the baffle plate is a hinged structure, and the upper or middle part of the baffle plate is connected with the breeding box through a hinged shaft. When the baffle needs to be opened, it is only necessary to turn the hinged shaft to overturn the baffle so that the light area and the 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...
