Agitated Thin Film Evaporator (ATFD)

Agitated Thin Film Evaporator

INTRODUCTION :

Welcome to the world of Agitated Thin Film Dryer (ATFD) and other heat transfer equipments. Ketav Consultant leads by virtue of superior engineering design capabilities, manufacturing excellence and a project based approach committed to deliver high performance total evaporation solution customized to our client requirement.

Ketav Consultant offer ATFD as a single point solution for all kind of drying application. Our ATFD's are running smoothly for production and effluent purpose in chemical Pharma, Textile , Food and Beverage Industries.

OPERATING PRINCIPLE :

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.

APPLICATIONS :

ATFD systems are used in Pharma Industries, Textile Industries, Agro Chemicals Industries , Sugar Industries And Effluent Treatment Plant. Drying of products, Drying of concentrated liquid for salt recovery, Drying of Chemical and petro chemical products to recover the powder.
