Description

Technical Field

[0001] This utility model relates to the field of tablet processing technology, specifically a powder shaking and sieving mechanism for tablet processing. Background Technology

[0002] Tablet processing is a crucial step in pharmaceutical preparation production. Its process flow and quality control are essential to ensuring the safety and efficacy of drugs. It involves mixing drug powders and excipients such as fillers, lubricants, and dispersants in a certain proportion. These raw materials need to undergo strict screening and testing to ensure that they meet production requirements.

[0003] In the preparation stage of tablet processing, meticulous sieving of the powder is an indispensable step. However, there is a problem that cannot be ignored in the traditional sieving process: unqualified powder often remains on the sieving seat. These powders that fail to pass through the sieve not only represent a direct loss of raw materials, but may also lead to a decrease in overall production efficiency. Since they cannot continue to participate in subsequent processing, they are considered a waste of resources. More seriously, if these residual powders are not properly handled, they may also pollute the production environment, thereby affecting the quality of the final product.

[0004] Therefore, a powder shaking and sieving mechanism for tablet processing is proposed. Utility Model Content
