Abstract:
The fluid-bed spray dryer was developed for PVA-film coating of the granules made of extract from Chinese traditional medicine. The experiment result indicated that the dissolution rate of granules from Dengzhanxixin Capsules wash't affected by PVA-film coating. The coated granules could be filled into capsules easily. Their stability was highly raised. This new technology basicalcy solved such problems as: easy moisture-absorbing of extract after vacuum drying at low temperature, difficult capsule-filling and poor stability, which led to the assurance and lift of preparation quality.
