The invention relates to an enamel double cone vacuum dryer, relates to the technical field of chemical equipment and is used for solving the technical problem existing in the prior art of material contamination by seal wear. The enamel double cone vacuum dryer comprises a barrel body and a support, because when the barrel body rotates, all vacuum filters do not rotate along with the barrel body,therefore, the barrel body is provided with one vacuum filter to be in a state of inclining upwards at any position, so that the phenomenon of the material contamination caused by the seal wear in therotating process of the cylinder body can be avoided.
