Problems solved by technology

Our country introduced and raised Tenebrio molitor from the Soviet Union in the 1950s. So far, it is still purely separated by hand. Manual separation makes it difficult to achieve large-scale and automated breeding of Tenebrio molitor.

Embodiment

[0020] Put 100g of Tenebrio molitor larvae into a long-hole sieve and a traditional mesh sieve respectively, let the larvae fall freely in a static state, observe and record once per minute, and compare the separation rates of the two. The separation rate of the long strip mesh screen in 1-5 minutes is significantly higher than that of the traditional mesh screen, and the separation purpose has been achieved.

[0025] After mixing 50g of Tenebrio molitor pupae and 50g of Tenebrio molitor larvae, place them in a strip-shaped sieve and a traditional mesh sieve respectively, and let the larvae fall freely in a static state, observe and record once per minute, and compare the separation of the two rate, with manual separation as a control. The pupa separation effect of the strip-shaped hole sieve is significantly higher ...

Abstract

The invention discloses a yellow mealworm and pupa separation method and relates to the technical field of separation devices. The yellow mealworm and pupa separation method comprises the steps that firstly, a screening tool is manufactured, wherein the screening tool is a long-strip-shaped mesh screen separator; secondly, yellow mealworms and pupas are placed in the screening tool manufactured in the first step to be screened; thirdly, the pupas will stay on a mesh screen and the yellow mealworms will drop from a screen mesh after screening, so that yellow mealworm and pupa separation is achieved. According to the yellow mealworm and pupa separation method, separation is rapid and accurate, time and labor are saved, and operation is convenient.

Description

Technical field: [0001] The invention relates to a method for separating Tenebrio molitor pupae, belonging to the technical field of separation devices. Background technique: [0002] When Tenebrio molitor enters the pupation stage, it is necessary to separate the pupae from the larvae in time. If it is carried out by manual operation, the efficiency is low. Our country introduced and raised Tenebrio molitor from the Soviet Union in the 1950s. So far, it is still purely manual separation. Manual separation makes it difficult to realize large-scale and automatic breeding of Tenebrio molitor. When the larvae grow to more than 12 instars, they begin to pupate. The pupal stage is a critical period for artificial breeding, which determines the success or failure of breeding Tenebrio molitor. Invention content: [0003] In view of the above problems, the technical problem to be solved in the present invention is to provide a separation device for Tenebrio molitor pupae. [0...
