Agitated Thin Film Drying (ATFD) is a thermal drying process designed to remove moisture from heat-sensitive materials. The material is introduced into a heated cylindrical drying chamber where it is spread into a thin film. This thin film is continuously agitated by rotating blades or mechanical stirrers to ensure uniform heat distribution and prevent clumping. As the material is heated, moisture evaporates, and the dried product is collected at the bottom. ATFD is particularly effective for materials that are prone to thermal degradation, such as heat-sensitive chemicals, pharmaceuticals, and food products, as it provides controlled drying with minimal exposure to high temperatures.
Types:
- Single-Stage ATFD: Simple, single-stage drying for smaller applications.
- Multi-Stage ATFD: Multiple drying stages, used for larger-scale or continuous processes.
