NOVELTY - The utility model claims a vacuum drying device for graphene production process, comprising a can be electromagnetic heating device of drying container, one end of the drying container through the rotary shaft is set on the bearing in the first supporting rod; the other end of the drying container set on the bearing on the second supporting rod through a rotating shaft, rotating shaft connected with the output end of the driving motor, the rotating shaft is provided with air duct, air duct connected with the vacuum pump through the exhaust pipe. The utility model uses the electromagnetic heating device to realize the heating process of the drying container. structure greatly simplifies the original heating device, at the same time, using the opened air duct and connected with the exhaust in the rotating shaft, which simplifies the connection structure between the vacuumizing device and the drying container, and finally improves the vacuum drying effect of graphene.
