Agitated thin film evaporator is confined mainly to the concentration of very viscous materials & heat sensitive liquids such as gelatin, antibiotics, fruit juices & solvent mixture etc. Feed is introduced at the top of evaporator & is spread by wiper blades on to the vertical cylindrical surface inside the unit. Evaporation of solvent takes place as the thin film moves down the evaporator wall. The heating medium normally is high pressure steam or oil.
ATFD is vertical centrally located rotor having closely fitted blades which rotates inside precision machined jacketed shell. Agitated Thin Film Dryer is mostly used for drying applications. It is a technology used to dry the concentrated solution so that moisture is evaporated & dry powder of solid is obtained. This equipment is mainly used in the industries such as pharmaceutical, food, dye industry, Recovery of solvent and products from thick dry residues. Zero liquid discharge plants for effluent, obtaining pigments from slurries, Crystallizing & Drying of Salts from solutions etc.
