Description

Technical Field

[0001] The utility model relates to the technical field of Chinese herbal medicine processing, in particular to a screening device for Chinese herbal medicine processing. Background Art

[0002] Traditional Chinese medicine is mainly composed of botanicals (roots, stems, leaves, fruits) and minerals. Since botanicals account for the majority of traditional Chinese medicine, it is also called Chinese herbal medicine. The processing of Chinese herbal medicine requires cleaning, cutting, screening, drying, sun drying, and baking. Since Chinese herbal medicines grow naturally, they have different shapes, volumes, thicknesses, etc. After cutting, the sizes will not be exactly the same. Therefore, Chinese herbal medicines need to be screened according to their volume, so that Chinese herbal medicines of different sizes can be separated and packaged according to different grades.

[0003] Since most Chinese herbal medicines are cultivated, there is usually dirt attached to them when they are collected or purchased. When the Chinese herbal medicines are screened, the dirt on their surface may have a certain thickness, causing the volume of the Chinese herbal medicine and the dirt to exceed the screening hole of the Chinese herbal medicine, causing the Chinese herbal medicine to enter the next screening hole, affecting the accurate screening and grading of the Chinese herbal medicine, which is not conducive to subsequent processing.
