Problems solved by technology
The advantage is that the surface of the granules produced by the wet method is wet, and has the advantages of good granule quality, beautiful appearance, strong wear resistance, and good compression molding performance. However, most of the existing wet granulation methods have high energy consumption and low precision. , uneven particle size and uneven content, and the above defects are difficult to overcome in the actual production process

The invention relates to a granule formation device, a formation method and granules. The granule formation device comprises a first rotating cylinder (1), a first motor (5), a crushing unit (6), a grinding unit (12) and a granule formation unit (19), wherein a second fan (28) is adopted to blow air flows to enable granules smaller than a first preset particle size to pass through a filtering net(27); a circulation channel (29) for circulating granules greater than the first preset particle size to the lower part of a second rotating cylinder (24) is arranged on one side at a lowermost end; the circulation channel is provided with a filtering net (27); granules greater than a second preset particle size are discharged upwards by using a cyclone separator (30); and granules smaller than the second preset particle size are fed into the circulation channel (29).
Description
technical field [0001] The invention belongs to the field of medicine preparation, and in particular relates to a granule forming device, a forming method and granules. Background technique [0002] Pharmaceutical granulation methods can be divided into three categories: wet granulation, dry granulation, and spray granulation, among which wet granulation is the most widely used. Wet granulation is a method in which a binder is added to the drug powder, and the powder is agglomerated together by the bridging or bonding effect of the binder to prepare granules. The advantage is that the surface of the granules produced by the wet method is wet, and has the advantages of good granule quality, beautiful appearance, strong wear resistance, and good compression molding performance. However, most of the existing wet granulation methods have high energy consumption and low precision. , uneven particle size and uneven content, and the above defects are difficult to overcome in the a...
