Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material screening, in particular to a Chinese medicinal material screening machine with a multi-level screening function. Background Art

[0002] In the production process of traditional Chinese medicine, the grading and screening of medicinal materials is an important processing step. Screening is a process of using a sieve to allow fine particles smaller than the sieve holes in the material to pass through the sieve surface, while coarse particles larger than the sieve holes are retained on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be seen as consisting of two stages: material stratification and fine particle screening. Material stratification is the condition for completing the separation, and fine particle screening is the purpose of separation. However, existing traditional Chinese medicine screening machines are generally single-stage screening, resulting in poor screening effect, requiring repeated screening, and the screening basket cannot be cleaned, resulting in clogging of the screening basket.
