Description

Technical Field

[0002] Granulation of Chinese medicine preparations refers to the process of forming granular pharmaceutical preparations by processing Chinese medicine powder through certain technical methods. Its purpose is to improve the dissolution characteristics of Chinese medicine, enhance its bioavailability and facilitate storage and administration. The granulation process usually includes wet granulation, dry granulation and extrusion granulation. Wet granulation is to combine Chinese medicine powder with a certain proportion of liquid to form moist granules, and then remove excess water by drying; dry granulation is to directly press the drug powder into granules through mechanical pressure, which is suitable for water-intolerant drugs; extrusion granulation is to mix the drug and excipients through extrusion equipment, extrude them into strips, and then cut them into granules.

[0003] The current granulation equipment for traditional Chinese medicine preparations separates the extruded long medicinal materials into granules by cutting during extrusion granulation. However, there are fibers inside the medicinal materials during molding, which makes the cut granules incomplete and lacks sorting function. When the medicinal granules that do not meet the standards are mixed, it will affect the subsequent packaging work. To this end, we provide continuous granulation equipment for traditional Chinese medicine preparations to solve the above problems. Utility Model Content
