Rototech Atfd Are Used To Concentrate, Refine Or Recover A Valuable Product
Through Distillation Or Similar Thermal Separation Process.
The Typical Agitated Thin Film Dryers Consists Of A Tubular Heat Transfer Area
With An External Heating Jacket And Fast Revolving Inner Rotor With Flexible Or
Rigid Wiper Elements.
The feed is distributed by the rotor and its wipers evenly over the heating
surface and forming a thin film of uniform thickness and heat will transfer in to
thin film, Feed progressively passes through different phases like Liquid Slurry,
Past Wet powder and finally powder of desired dryness.
The vapors produced and flow counter current to the film and pass through
cyclone separator, further these vapors condensed in to indirect contact
The powder gets collected in a receiver at the bottom.
