AUTOMATIC VACUUM DRYING DEVICE

摘要

An automatic vacuum drying device comprises a drying oven, a heating device used to heat the drying oven, a vacuum extraction device used to evacuate the drying oven, a nitrogen input device used to input nitrogen into the drying oven, and a transporting device located inside the drying oven and used to transport materials, two first openings are located at two opposite sides of the drying oven, an automatic sealing door is mounted on at least one of the first openings, the automatic sealing door includes a first door plank and a second door plank parallel to the first door plank, an elevator structure is located between the first door plank and the second door plank, the elevator structure is used to lift the first door plank and the second door plank. The automatic vacuum drying devices can form an automatic vacuum drying production line conveniently, and the automatic vacuum drying production line has high degree of automation, and high processing efficiency, such that it is possible to drastically improve the vacuum drying efficiency.
