Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum drying ovens, and in particular relates to a vacuum drying oven for producing electrode cores. Background Art

[0002] The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposable and easily oxidizable materials. When working, it can maintain a certain degree of vacuum in the working chamber 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. First, a vacuum pump is used to reduce the air pressure in the box to achieve the purpose of lowering the boiling point of water. After that, the internal heating evaporates the water into water vapor and the water vapor is extracted through a vacuum extraction device to achieve the purpose of drying special items. At present, the existing vacuum drying ovens mostly have a fixed flat tray for placing items. When the items are placed on the flat tray for drying, there is a problem that the internal hot air cannot be effectively circulated, and the heating and drying efficiency is low.
