A winnowing device for the production and processing of Chinese medicinal decoction pieces

Abstract

The invention discloses a winnowing device for production and processing of decoction pieces of traditional Chinese medicine, which comprises a material tray, a telescopic drive rod and a Z-shaped scraper frame. In the present invention, a set of middle-rotating combined disks is provided, and several annular supporting plates with different outer diameters are sequentially sleeved in the middle-rotating combined disc group from outside to inside. Several annular supporting plates have the same thickness in the radial direction, and the adjacent annular supporting plates The supporting plates are screwed together, the outer fixed ring plate and the inner drive plate are fixed, and the inner drive plate is screwed in the middle of the middle rotation combination plate group. The rotation of the inner drive plate can realize the tower shape change of the center rotation combination plate, specifically the upper tower and the lower The tower-shaped switching can realize the tumbling of the decoction pieces in the process, and the air duct is set between the adjacent annular supporting plates. When the adjacent annular supporting plates are misaligned, the lateral movement of the air flow can be realized. The upper end of the supporting plate is equipped with a Z-shaped scraper , The Z-shaped scraping frame rotates with one of the annular support plates, and then lifts the material on the adjacent outer annular support plate, so that the dust in the decoction pieces is fully exposed and the dust is thoroughly removed.

Description

technical field [0001] The invention relates to the field of dedusting technology for decoction pieces of traditional Chinese medicine, in particular to a winnowing device for production and processing of decoction pieces of traditional Chinese medicine. Background technique [0002] Traditional Chinese medicine is divided into Chinese patent medicine, Chinese herbal medicine, and Chinese herbal decoction pieces according to the processing technology. During the processing of Chinese herbal medicine pieces, winnowing is often required to remove light dust impurities, especially for mass production and processing. The prior art The winnowing machine is actually an agricultural lifting machine, which is not convenient to operate in the workshop, and it is easy to cause dust in the workshop, and it takes a lot of labor. For this reason, there are some winnowing machines on the market. The winnowing principle is similar to the bag dust removal structure. , all make the Chinese h...

Problems solved by technology

[0002] Traditional Chinese medicine is divided into Chinese patent medicine, Chinese herbal medicine, and Chinese herbal decoction pieces according to the processing technology. During the processing of Chinese herbal medicine pieces, winnowing is often required to remove light dust impurities, especially for mass production and processing. The prior art The winnowing machine is actually an agricultural lifting machine, which is not convenient to operate in the workshop, and it is easy to cause dust in the workshop, and it takes a lot of labor. For this reason, there are some winnowing machines on the market. The winnowing principle is similar to the bag dust removal structure. , all make the Chinese herbal decoction pieces use the blanking method to separate the impurities from the decoction pieces, and then use the fan to discharge the impurities, but how to maximize the dust in the Chinese herbal decoction pieces is completely exposed is a problem, that is to say, the Chinese herbal decoction pieces have a certain quality , its fluidity is poor, and the rolling effect is poor. As a result, there will be weak wind between the Chinese herbal pieces, making it difficult to fully discharge the dust.
