The growing appeal of continuous coating processes has occurred in no small part because 1) O'Haras innovative zero waste system for start-up and shut-down and 2) it is possible to operate the Fastcoat™ continuous coater in batch mode. Yet one big challenge of continuous coating has remained: The short residence time of tablets within the coating pan (typically 15 to 25 minutes). This short period imposes a significant burden on the ability to deposit the requisite amount of coating material. High-solids coating systems resolve this problem and make available the major benefits of continuous coating, including:
- Rapid throughput (with shorter coating process times).
- Less exposure to harsh processing conditions.
- More uniform distribution of the coating material and Less coating material required.
