Description

Technical Field

[0001] The utility model specifically relates to a rotary medicine screening machine with adjustable screen aperture, belonging to the technical field of medicine screening machines. Background Art

[0002] Traditional Chinese medicine screening is an important link in the preparation process of traditional Chinese medicine. It mainly involves separating traditional Chinese medicine materials according to their particle sizes for subsequent further processing and preparation. Through screening, traditional Chinese medicine materials with relatively uniform particle size distribution can be obtained, which is of great significance for ensuring the quality of medicines and improving the uniformity and stability of preparations. When screening traditional Chinese medicine, a medicine screening machine is needed. However, when the existing medicine screening machine is in use, traditional Chinese medicine materials are placed on a filter screen plate for filtering and screening. The filter screen plate is usually fixed inside the machine, making it inconvenient to replace. It can only screen out traditional Chinese medicine of a single particle size and cannot achieve multi-stage screening of traditional Chinese medicine, so there are certain drawbacks in the use process.
