The embodiment of the invention relates to the technical field of material drying, in particular to a vacuum dryer which comprises a tank body, a vacuumizing device and a pressure difference detectiondevice. Wherein one end of the vacuumizing device is located in the tank body, a filtering part is arranged at the end, located in the tank body, of the vacuumizing device, the vacuumizing device isused for carrying out vacuumizing operation on the tank body, and the vacuumizing device is used for carrying out vacuumizing operation on the tank body during the vacuumizing operation. Gas in the tank body is pumped out through the filtering part; and the pressure difference detection device is used for detecting the pressure difference between the tank body and the vacuumizing device. Accordingto the utility model, the filtering part can be automatically cleaned, the work of repeated manual disassembly, filtering part cleaning and the like is avoided, the failure rate of equipment is reduced, and the production effi
