Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a vacuum drying box. Background Art

[0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidizable substances. It can maintain a certain degree of vacuum in the working room during operation, and can be filled with inert gas. In particular, some items with complex ingredients can also be dried quickly. An intelligent digital temperature regulator is used to set, display and control the temperature. The vacuum drying oven is an older drying device, and the inside of the oven is divided into several layers by a heating plate. Hot water or low-pressure steam is passed into the heating plate as a heating medium. The tray with the medicine to be dried is placed on the heating plate, the door of the oven is closed, and the inside of the oven is evacuated with a vacuum pump. The heating plate heats the medicine to the specified temperature in the circulation of the heating medium, and the water begins to evaporate and is gradually drawn away as the vacuum is drawn. This equipment is easy to control and can condense and recover the evaporated solvent. The medicine is not easily contaminated during the drying process, and can be used for medicine drying, packaging material sterilization and heat treatment;

[0003] A vacuum drying oven according to patent publication number CN215373180U belongs to the technical field of drying ovens.
