Insect-egg-and-pupa low-temperature drying device and method for drying insect eggs and pupae thereof

Abstract

The invention discloses an insect-egg-and-pupa low-temperature drying device and a method for drying insect eggs and pupae thereof. The device comprises a box body, blades and a mesh tube, a refrigerating tube is installed on the left wall of the interior of the box body, a separating net is fixed to the interior of the box body, the blades and a driving motor are mutually connected through a connecting shaft below, a driving motor is installed on the right surface of the interior of the interior of the box body, the mesh tube and a rotary shaft are mutually connected through a supporting rodarranged at a left end port, scattering blades are arranged on the outer side of the rotary shaft, and a feeding hopper is installed on the upper surface of the box body. The method comprises the steps that wet eggs (pupae) are placed in the box body, the driving motor is started, and the mesh tube is driven to rotate by the driving motor to perform low-temperature drying on the wet eggs. According to the device and the method, the problems of interior or even surface rapid moisture losing of eggs and pupae on a surface layer caused by rapid air drying at room temperature or high temperature,poor survival of insects, reduced production suitability and the like can be prevented.

Description

technical field [0001] The invention relates to the technical field of insect eggs and pupae, in particular to a low-temperature drying device for insect eggs and pupae and a method for drying insect eggs and pupae. Background technique [0002] In the production process of parasitic natural enemies, during the collection and treatment of intermediate host eggs and parasitic wasps, the host eggs and pupae are often soaked in clean water or medicinal liquid due to the need for disinfection, purification or separation. The processed insect eggs and pupae often need to be dried and separated before entering the next production link. Agglomeration in the process, and processed ovum, chrysalis usually need more than 6~8 hours time to dry in the outdoor state in the processing process and just can fully disperse and be used for next raising link. [0003] To speed up this process, breeders usually need to dry the rearing material at a higher temperature. Whether the insect materi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a low-temperature drying device for insect eggs and pupae and a method for drying insect eggs and pupaes thereof, so as to solve the problem that in the current large-scale production of small insects proposed in the above-mentioned background technology, it takes a long time to dry the soaked eggs and pupae. Insects develop during this process leading to problems with inappropriate reproduction in the next stage
