Agitated Thin Film Dryers are used to dry liquid solutions or slurries into flakes or powder. Agitated thin film dryer consists of a jacketed vertical shell having an agitator shaft mounted with multiple blades on it. Either steam or hot oil is passed through the jacket of the shell thereby heating the internal surface of the shell to required tem perature. The liquid feed is introduced at the top and the dry product is discharged at the bottom.
