Stewing and calcining device for traditional Chinese medicinal materials

Abstract

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 uncarbonized traditional Chinese medicinal materials are more easily heated. In a stewing and calcining process, an air pump and air valves at the two ends of an air pipe are opened, and air internal circulation is formed in the sealing cylinder, so that the traditional Chinese medicinal materials at all positions are heated more uniformly. Compared with the prior art in which no special stewing and calcining device exists, the stewing and calcining device for the traditional Chinese medicinal materials is designed, and the heating uniformity of the traditional Chinese medicinal materials in the stewing and calcining process can be effectively improved through the stewing and calcining device for the traditional Chinese medicinal materials.

Description

technical field [0001] The invention relates to the technical field of stewing and calcining apparatus for Chinese medicinal materials, in particular to a device for stewing and calcining Chinese medicinal materials. Background technique [0002] Stew calcining (button calcining) is a link in the process of Chinese herbal medicine processing. That is to heat the Chinese medicinal materials to carbonize them in anaerobic / anoxic / poor oxygen state. [0003] There is no special device for traditional simmering, but two interlocking pots are used as containers. The general operation is as follows: [0004] The medicinal materials before calcining are picked and graded. The medicine in the pot should be properly loaded. Generally, the amount of the pot should not exceed 1 / 3 of the capacity of the pot. When stewing and calcining, the upper pot should be smaller than the lower pot, and heavy objects should be pressed. The joints are first blocked with wet paper, then sealed wit...
