Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a raw material screening device for tablet production. Background Art

[0002] Tablets refer to sheet preparations made of drugs, pesticides and suitable excipients through formulation technology. Tablets are composed of original drugs, fillers, adsorbents, binders, lubricants, dispersants, wetting agents, disintegrants, flavors, colorants, etc. The materials are first crushed, granulated, and dried, and then made into tablets using a tablet press. Some do not require granulation and drying and are directly pressed into tablets. When screening the raw materials for tablets, a screening device is required.

[0003] At present, there are still some shortcomings in the traditional screening device. When screening tablet raw materials, the tablet raw materials are generally poured into the screening net inside the screening device, and then the screening net screens the tablet raw materials. Over time, tablet raw materials will remain on the screening net, which can easily cause the screening net to be blocked. For this reason, it is necessary to stop the machine to clean the screening net, thereby reducing the efficiency of the screening device in screening tablet raw materials. For this reason, we propose a tablet production raw material screening device. Utility Model Content
