Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a new type of pharmaceutical granulator. Background Art

[0002] Drug granules are a very important component of drugs. Granulation methods include wet granulation, dry granulation, one-step granulation and spray granulation. Among them, wet granulation is the most widely used. Generally, multiple drug powders are mixed and bonded together with a binder, and then granulated inside a granulator to obtain drug granules.

[0003] When using a pharmaceutical granulator to make granules, the raw materials are usually stirred inside the machine and cut directly by a cutting knife. Although the raw materials can be quickly cut into granules, the sizes of the granules after cutting are different, and the drug content inside the granules is not uniform, which reduces the quality of the medicine.
