Intermediate pharmaceutical products
Drying of intermediate pharmaceutical products is an extremely quality-determining process step. The thin film dryer Contivac is the most adequate dryer to handle such demanding targets. This dryer operates with the same thin film principle as described for the horizontal thin film dryer. Compared to the paddle dryer, the product hold-up in the Contivac is small and the residence time is extremely short. Reducing the residence time by 500 times has the following effects:
- Reduction of side reactions
- Reduction of colour changes
Fast drying is only one of the great advantages of the Contivac. It opens many others possibilities for pharmaceutical products. Additional substances can be evenly sprayed on the thin film in the Contivac with rotating nozzles. In addition, the heating jacket can be split into different heating zones and further feed nozzles can be considered at several positions. This allows a most flexible design in order to produce thermal sensitive pharmaceutical products.
