Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceuticals, and in particular relates to a vacuum drying device. 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 vacuum degree in the working chamber during operation and can be filled with inert gas. In particular, some items with complex ingredients can also be dried quickly.

[0003] The above device does not have a structure for fixing the drying tray of the drying box and improving the drying efficiency when in use, so that when the vacuum drying box is in use, if the undried material on the tray is heavy and the protective door is open, the tray may slide due to the weight, thereby causing material contamination. At the same time, during the drying process, most materials are first placed in the material tray and then placed on the tray. However, this method will cause uneven temperature of the contact surface between the material tray and the tray when in use, resulting in slower drying of the material at the bottom of the material tray, which is inconvenient to use. Based on the deficiencies in the existing technology, the utility model designs a vacuum drying device. Utility Model Content
