NOVELTY - The utility model relates to the technical field of drying device, especially relates to a drying device of graphene. the drying device of the graphene comprises a drying chamber; the upper end of the drying chamber is a heating area, composed of a layer of clapboard; the clapboard is connected with the thermocouple wiring terminal and an electric heater; the lower end of the drying chamber is a refrigerating area, composed of a cold trap, the cold trap is connected with the compressor and the condenser; one side of the drying chamber is further connected with a rotary vane pump. The structure of the drying device of graphene is simple; the multi-layer clapboard is dispersed and dried; it can realize fast drying speed, high efficiency, and can be observed in real time, electric heating mode does not need to use dry material containing acidic solvent, and finally drying the water vapour is discharged through the cold trap condensation, and the bottom of the drying chamber is provided with a water discharging valve.
