Vacuum Freeze Dryer

Abstract

The invention relates to a vacuum freeze drier. The vacuum freeze drier comprises a machine body and a drying chamber, wherein the drying chamber is horizontally arranged in the machine body and is ina cuboid shape, one side of the machine body is provided with an end cover, the end cover is arranged at the position corresponding to the opening of the drying chamber, the section area of the end cover in the vertical direction is larger than that of the opening, an annular plate I can move in the drying chamber, the outer wall of the annular plate I is attached to the inner wall of the dryingchamber in the moving process, the inner wall of the drying chamber is fixedly connected with an annular plate II, the distance between the annular plate II and the opening of the drying chamber and the distance between the side, far away from the end cover, of the annular plate I and the surface of the end cover are consistent, and a limiting assembly capable of limiting the end cover is arrangedon the machine body. The vacuum freeze drier has the good sealing property.

Description

technical field [0001] The invention relates to a drying machine, in particular to a vacuum freeze drying machine. Background technique [0002] A dryer is a mechanical device that uses thermal energy to reduce the moisture content of materials and is used to dry objects. The dryer vaporizes and escapes the moisture in the material (generally refers to water or other volatile liquid components) by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. Vacuum freeze dryer is suitable for drying materials such as high-grade raw materials, traditional Chinese medicine decoction pieces, biology, wild vegetables, dehydrated vegetables, food, fruits, chemicals, and pharmaceutical intermediates. Freeze vacuum drying is a new type of box structure introduced by the vacuum freeze dryer that combines the refrigeration system, vacuum system, heat transfer oil heating system, and moisture ...

AI Technical Summary

Problems solved by technology

[0004] In the above technical solution, although the staff can close the drying chamber by turning the revolving door, the sealing is only through the mutual fit between the revolving door and the side wall of the fuselage. This sealing method has poor sealing performance and the sealing effect will be directly affected. Affect the drying effect of materials in the drying room
