Electric heating rotary drying device

The utility model discloses an electric heating rotary drying device and belongs to the technical field of preparation equipment structures. The device comprises a feeding assembly, a transmission and supporting assembly, a barrel assembly, an electric heating assembly and a discharging assembly. In the barrel assembly, the spiral blade is fixed and combined with the bolt through welding, so that the maintenance frequency of the inner-layer barrel is reduced. The electric heating assembly is provided with six heating areas, and under the action of the heat insulation layer, the heat loss of the inner-layer barrel is small, and the temperature is constant. Materials are fed into the device through the spiral conveyor and enter the inner-layer barrel body to be roasted and dried, the dried materials are discharged through the discharging assembly, an electric heating mode and a spiral blade fixing mode are improved, energy consumption losses are reduced, and the service life of the device is prolonged. 一种电加热回转烘
