Medicinal material oven with uniform heat energy

The invention discloses a medicinal material oven with uniform heat energy. The medicinal material oven comprises a box body and a box cover, wherein a medicine placing device is arranged in the box body, a heating device is arranged at the bottom of the box body, two telescopic rotating devices are symmetrically arranged in the box cover, each telescopic rotating device comprises a sleeve, a telescopic sleeve and a twisting and shearing type telescopic fence, the telescopic sleeve drives the twisting and shearing type telescopic fence to stretch and retract, when the telescopic fence is stretched, medicinal materials on the medicine placing device are stirred through the the twisting and shearing type telescopic fence, so that the medicinal materials are heated more uniformly, and meanwhile, when large-batch medicinal materials are processed, the medicinal materials can be uniformly heated, so that the situiation that partial medicinal materials cannot be effectively dried due to thefact of mutual stacking a
