ATFD is stands for evaporation of water/solvents to make concentrated liquid to dry powder or flakes.
ATFD is the ideal apparatus for continuous processing of concentrated material to dry solids. ATFD is consist 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.
The turbulance increases as the product passes through the clearance before entering calming zone situated behind the blades as the heat will transfer from jacket to main shell under the smooth agitation water/solvent will evaporate and liquid will convert to slurry, to cake or to dry powder or flex.
The vapors produced rise upward, counter-curruentlyto the liquid and pass through Cyclone separator mounted of vapor outlet of ATFD.
Further these vapor will be condensed in condenser and recovered as condensate. System will be Operated under vacuum for temerature sensitive products and atmospheric condition for normal drying.
