Description

Technical Field

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

[0002] Drug granules refer to dry granular preparations with a certain particle size made by mixing raw materials and appropriate excipients. In addition to the main drug, the composition of the drug granules can also add appropriate amounts of flavoring agents, fragrances, colorants, dispersants and preservatives as needed. The drug granules can be swallowed directly or washed down with water for drinking. During the processing of drug granules, a small amount of broken and non-standard drug granules are easily mixed in the drug granules. The drug granules need to be screened to ensure that the drug granules entering the packaging production line are in whole granules.
