Due to our proficiency in this field, we are engaged in presenting Agitated Thin Film Dryer (ATFD). It stands for evaporation of water or solvents to make concentrated liquid to dry powder or flakes. Most commonly, these systems are used in Pharma Industries, Textile Industries, Agro Chemicals Industries , Sugar Industries And Effluent Treatment Plant for drying of products, drying of concentrated liquid for salt recovery, drying of chemical and petro chemical products to recover the powder.

Manufactured range of dryer is ideal for thermal treatment of solutions and heat sensitive products because of its inherent design features, where reduced operating temperatures and vacuum operating pressures are desirable. This Agitated Thin Film Evaporator consists of cylindrical, vertical body with heating jacket and a rotor inside of the

shell which is equipped with rows and pendulum blades all over the length of the dryer. The hinged blades spread the wet feed product in a thin film over the heated wall.

Further more, we manufacture this dryer having a tubular heat transfer area with an external heating jacket and a fast-revolving, inner rotor with flexible or rigid wiper elements. The driving speed is adapted to the product being handled, its particular specifications and task.

The instability increases as the product passes through the clearance before entering calming zone which is situated behind the blades as the heat will transfer from jacket to main shell under the smooth agitation water or solvent will evaporate and liquid will convert to slurry, to cake or to dry powder or flex.

Then the vapours produced and rise upward, counter-currently to the liquid and pass through a cyclone separator mounted of vapour outlet of ATFD. Besides, these vapours will be reduced in condenser and recovered as condensate. After that the system will be operated under the vacuum for temperature sensitive products and atmospheric condition for normal drying.
