Agitated Thin Film Dryer is used to dry a solution of high TDS Water or Products. The outlet of ATFD will be in the Powder form having 10-15% moisture. This system will evaporate the solution by thin layer formation on the Surface.
ATFD is stands for evaporation of water/solvents to make concentrated liquid to dry power or flakes. Based on application either recover solvent or dry product in important.
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 flim over the heated wall.
The turbulance increase 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 the under the smooth agitation water/solvent will evaporate and liquid will convert to slurry, to cake or to dry power 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 condesate. System will be Operated under vacuum for temperature sensitive products and atmospheric condition for normal drying.
