With the improvement of the understanding of traditional Chinese medicine at home and abroad, the demand for traditional Chinese medicine has increased year by year. Chinese herbal medicine slices are Chinese herbal medicines that have been processed and prepared according to the theories and methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. They include some Chinese herbal medicine slices processed at the place of origin, original herbal medicine slices, and slices that have been cut and processed.

[0003] In the process of processing Chinese herbal medicines, modern equipment is needed to improve production efficiency, such as medicine cutters that slice the herbs evenly and dryers for drying. These equipment are conducive to the later processing and utilization of Chinese medicines. Before processing, some Chinese herbal medicines need to be dusted on the surface, that is, dust and impurities must be removed in advance before production and processing to improve the quality and appearance purity of the herbs, especially some Chinese herbal medicines with wrinkles on the surface are more likely to have residual impurities attached.

[0004] For example, the Chinese invention patent application document, with publication number CN117600075A, discloses a filter cartridge back-blowing device for drying and dust removal of traditional Chinese medicine, which relates to the technical field of traditional Chinese medicine processing, and comprises an arc-shaped cylinder, wherein a drying mechanism is arranged inside the arc-shaped cylinder, a dust removal mechanism is slidably connected to one side of the drying mechanism, and a heat dissipation mechanism is fixedly connected to the bottom of the dust removal mechanism. When the medicinal materials fall on the vibration plate, the vibration plate can be squeezed to tilt around the rotating bolt, and after the tilt, the medicinal materials on the surface of the vibration plate slide onto the spiral plate and continue to slide down along the spiral plate, and the spring under the vibration plate is reset after being squeezed, and under the reset, the vibration plate has a rebound effect on the medicinal materials that are about to fall in from above, that is, the medicinal materials are beaten, and the dust on the surface of the medicinal materials can be preliminarily removed.

There are more than three contact ring bodies 2, which are arranged in sequence between the inner walls of the two ends of the tank body 1, which can facilitate the realization of more dust removal effects.

[0031] An inner ring groove is provided on the inner wall at one end of the contact ring body 2, and an outer ring groove is provided on the outer wall at the other end. The inner ring grooves and outer ring grooves between adjacent contact ring bodies 2 are overlapped and connected, so that the contact ring bodies 2 can be stably sealed and docked. The end of the dust collecting groove 201 close to the edge is located in the inner ring groove. The dust collecting grooves 201 are evenly distributed in the contact ring body 2, and the number of the dust collecting grooves 201 is more than 12. The inner ring groove is provided with an auxiliary groove 203 connected with the dust collecting groove 201, so that the dust collecting groove 201 can be improved. The dust groove 201 is in contact with the gas transmitted by the blocking channel 204. A blocking channel 204 is provided in the contact ring body 2.

Usually, mud and sand impurities can sink and fall after being separated from the Chinese herbal medicine slices, while rotten skin is often mixed with the Chinese herbal medicine slices and is difficult to separate. Therefore, further separation treatment is required, which will increase the processing steps and greatly affect the production efficiency. The guide partition 60 The shape of 1 should conform to the size of the contact ring body 2, and is used to guide the airflow to surround the inner wall of the contact ring body 2 and blow it to the tumbling medicinal slices. In order to further enhance the tumbling effect, the contact ring body 2 located at the discharge port 103 is preferably provided with a separate power drive to ensure that the medicinal slices can be lifted. This can enhance the functionality of the device and improve product quality. For the medicinal slices that have been dusted, the relevant dust collecting trough 201 and the discharge channel 204 and other dust removal structures can be removed, and the corresponding contact ring body 2 can be widened to enable the medicinal slices here to be lifted more effectively.

[0037] When in use, the medicinal slices are turned over at the contact ring body 2, and the airflow fan 6 can blow the airflow to the other side, thereby making the light impurities float up and fall into the pull-out box 5, and then they can be processed at a regular time.
