AI Technical Summary
Existing small granule drug coating machines suffer from problems such as difficulty in cleaning deposits inside the drum, uneven coating thickness, unstable drug quality, and serious waste of raw materials during the cleaning and coating process.
The system employs a uniform mixing and circulation mechanism. The rotating tube and stirring blades driven by a motor tumble the agent, and a liquid pump is used to recycle the coating solution, ensuring uniform spraying of the coating solution and recovery of excess liquid that has not been absorbed.
It improves the uniformity and efficiency of coating, reduces the defect rate, lowers raw material costs, and ensures the stability of drug quality and production efficiency.
