Agitated Thin Film Dryer, Vertical

The most energy efficient dryer in the market. Thermal efficiency exceeds 90%

A vertical Agitated Thin Film Dryer (ATFD-V) has a centrally located rotor having closely fitting blades. It rotates in a precision-machined jacketed shell.
The feed is converted into a thin film, which is intensely agitated due to action of the high-speed rotor. The feed material goes through phases of slurry, paste and wet powder, before coming out as a dry powder.
