Stewing and calcining device for traditional Chinese medicinal materials

The invention discloses a stewing and calcining device for traditional Chinese medicinal materials. The stewing and calcining device comprises a sealing cylinder, an overturning cylinder and a gas conveying mechanism. According to the technical scheme of the invention, the traditional Chinese medicinal materials to be stewed and calcined are filled in the overturning cylinder and overturned in a heating process. Due to the fact that the cylinder wall of the overturning cylinder is inwards provided with conical protrusions and sieve holes used for leaking chippings, when the traditional Chinese medicinal materials are overturned in the overturning cylinder, the traditional Chinese medicinal materials collide with the conical protrusions, due to the fact that outer skins of the carbonized traditional Chinese medicinal materials are loose in texture, fall off after being collided and are discharged from the sieve holes, inner cores of the uncarbonized traditional Chinese medicinal materials are exposed, and the
