NOVELTY - The utility model claims a vacuum drying device for producing graphene, comprising a drying box; the drying box is equipped with a turning structure; the top of the drying box is fixedly installed with an adsorption structure; the utility model relates to the graphene production equipment technology field; the motor can drive the first rotating rod to rotate; the first rotating rod passes through the chain wheel component; the chain and the second rotating rod drives the eccentric wheel to rotate; the eccentric wheel is propped against the material net rack; because of the elasticity of the spring, the net rack will drive the material in the material to vibrate so that the material is turned; the turning structure can make the material dry in all directions, avoiding the material local high temperature condition; the quality of the material drying is improved; the circulating pipe can guide the hot air containing water vapour into the adsorption tank; the adsorption net will absorb the water vapour in the hot gas; the hot gas after adsorption is discharged into the drying tank through the circulating pipe again, preventing the water vapour from affecting the drying quality of the material.
