Description

Technical Field

[0001] This utility model belongs to the field of multi-stage screening technology, and in particular relates to a grading and screening device for the preparation of traditional Chinese medicine decoction pieces. Background Technology

[0002] Chinese medicinal herbs are processed medicinal materials that have been processed according to the theories and methods of traditional Chinese medicine and can be used directly in clinical practice. In order to ensure the quality of Chinese medicinal herbs, after production, they need to be screened by using a screening device to separate the internal debris from the qualified herbs.

[0003] There are many types of Chinese medicinal herbs, including raw material slices and processed medicinal herbs. During the production process, Chinese medicinal herbs are easily mixed with substances such as stones, dust, drug residues, and debris, which require screening. At the same time, they also need to be graded according to the size of the medicinal herbs. Existing multi-stage screening devices have reliable grading effects. However, when a batch of medicinal herbs only needs to be divided into 3 sizes, and the screening machine has more than 3 layers of screens, it is impossible to quickly remove the corresponding screen according to the actual size. Although multi-stage screening can be achieved, the flexibility of use needs to be improved.

[0004] To address the aforementioned issues, this application proposes a grading and screening device for the preparation of traditional Chinese medicine decoction pieces. Utility Model Content
