Description

Technical Field

[0001] The utility model belongs to the technical field of tablet medicine production, in particular to a swing-type granulator for tablets. Background Art

[0002] Tablets are flaky preparations made from drugs, pesticides, and appropriate excipients using pharmaceutical formulation technology. They consist of the active ingredient, filler, adsorbent, binder, lubricant, dispersant, wetting agent, disintegrant, flavoring, and colorant. The material is first crushed, granulated, and dried before being pressed into tablets using a tablet press. Some tablets are directly compressed without granulation or drying. Tablet quality requires accurate content, minimal weight variation, a disintegration time or dissolution rate that meets regulations, appropriate hardness, an attractive appearance, good color, compliance with health inspection standards, and stability during the specified storage period. Tablets should have accurate dosage, stable physical and chemical properties, a long shelf life, ease of use, transportation, and portability, low price, and high production volume.
