This vacuum drying oven is specially designed for new products for baking battery pole pieces. The vacuum chamber is cylindrical, which is convenient for loading the entire roll of battery pole pieces and baking under vacuum. The 4 vacuum chambers control heating separately and work independently. At the same time, the vacuum system adopts a digital display vacuum gauge to automatically control the upper and lower limits of the vacuum degree. Both the outside of the vacuum chamber and the central axis are equipped with heating devices, and are respectively equipped with high-precision temperature controllers to control the temperature. A circular observation window is set in the middle of the round door of the vacuum chamber.
