Description

TECHNICAL FIELD

[0001] The utility model relates to a solid preparation granulating equipment and belongs to the technical field of medicament preparation. BACKGROUND

[0002] As a solid preparation form of traditional Chinese medicine, the production of large honeyed pills traditionally relies on manual rolling. However, manual rolling is inefficient and cannot meet the demand for large-scale production in the modern traditional Chinese medicine industry. Furthermore, manual operation requires a high labor intensity from workers, and long-term manual labor not only easily causes fatigue problems for workers, but also may affect the uniformity and consistency of rolling due to inconsistent operation, thereby negatively affecting the efficacy of large honeyed pills.
