Description

A screening device for granule production

Technical Field

The utility model relates to the technical field of particle screening, in particular to a screening device for granule production.

Background technique

Granules are dry granular preparations with a certain particle size made by mixing raw materials and excipients. They are generally soluble granules, suspension granules and effervescent granules. They can be swallowed directly or taken with warm water. They are convenient to use and carry. The granule process steps include: raw material crushing, sieving, raw material and excipient mixing, granulation, drying, granulation and packaging;

In the process of granule production, the diameters of the granules vary and they are prone to condense into larger granule blocks, so the granules need to be screened; however, the existing screening devices cannot classify, transport and collect the granules after screening them, which makes it inconvenient to collect the granules; at the same time, the existing screening devices cannot perform secondary screening on the granules, resulting in poor screening effect; therefore, we propose a screening device for granule production to solve the above problems.
