Drone pupa freeze-drying device

Abstract

The invention provides a drone pupa freeze-drying device. The drone pupa freeze-drying device comprises a housing, wherein the whole housing is cylindrical; an upper board edge of a partition board is connected with the top of the housing through a rotating shaft, and a lower board edge of the partition board is connected with the bottom of the housing through the rotating shaft; the housing is divided into a closed freeze-drying chamber and a closed cold trapping chamber by the partition board; a bearing and supporting unit is fixed to the board surface of the partition board; and the partition board rotates around the rotating shaft to enable the bearing and supporting unit to be located in the freeze-drying chamber or the cold trapping chamber. According to the drone pupa freeze-drying device disclosed by the invention, the partition board is used for dividing the housing into the closed freeze-drying chamber and the closed cold trapping chamber, and the bearing and supporting unit is located in the freeze-drying chamber; after drone pupas are frozen in the freeze-drying chamber, the partition board rotates around the rotating shaft so as to enable the bearing and supporting unit to be located in the cold trapping chamber for drying the drone pupas; and the freeze-drying chamber and the cold trapping chamber are formed by dividing the housing, so that the occupied space is small, the arrangement is convenient, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of bee product processing equipment, in particular to a drone pupa freeze-drying device. Background technique [0002] Drone pupae refers to the vegetative body during the metamorphosis period after the male larvae of the honeybee is capped and before it emerges from the house. In the freeze-drying technology of drone pupae, the principle is to freeze the material to be dried at a low temperature below its eutectic point, so that The moisture in the material turns into solid ice, and then in a proper vacuum environment, the temperature is gradually raised under a proper vacuum degree (1.3-13 Pa), so that the ice is directly sublimated into water vapor and removed, and then the condensation in the vacuum system is used The device condenses water vapor to dehydrate the material at low temperature to obtain a dry product. [0003] In the prior art, the freeze-drying box and the cold trap are connected by connecting pipe...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the freeze-drying box and the cold trap are connected by connecting pipes, and the connecting pipe needs to be installed with a large hole on the freeze-drying box and the cold trap, and a large flange should be installed, and an on-off valve should be installed in the middle of the connecting pipe, resulting in a complex structure, The cost is high, and manufacturing and assembly are difficult; the freeze-drying box and the cold trap are two independent containers arranged horizontally side by side, and the manufacturing cost is high, the space is large, and the assembly and transportation are inconvenient
