1.5 M2 Agitated Thin Film Dryer (Feed Rate: 75 Kg/hr)

Agitated thin-film dryer (ATFD) is used for continuous drying of heat-sensitive products under vacuum with total solvent recovery. ATFD provides high throughput by efficiently working under vacuum. ATFD uses indirect heating and drying in inert conditions which is effective for heat and oxygen sensitive products. At FABEX, we have designed our vertical ATFD to be effectively used for wide range of process fluids including liquids, slurries and pastes. These process fluids are converted to free flowing solids by continuous single pass operation. High turbulence is provided by the use of hinged rotor blades. The clearance between the blades and the heated wall surfaces prevents fouling and can allow volatiles to easily escape. The products obtained through drying by our modernized and dynamic vertical ATFD are of highly desirable quality.
Principle of Operation: Continuous processing of concentrated materials to dry solids by using intense agitation for effective heat transfer. The heating surface is renewed by continuous scrapping of dry solids for efficient heat transfer.
Agitated Thin Film Dryer
A promising alternative to conductive drying technologies, Agitated Thin Film Dryer (ATFD) obtains the energy for evaporation by indirectly contacting the product with hot air/steam and making a thin film. The material to be dried is placed in a vertical chamber with a high speed rotor. The rotor maintains the film by adhering it to the surface of the walls to have an efficient heat transfer rate. The liquid material slowly changes its form due to high heat transfer rates, eventually forming a dry powder. Agitated Thin Film Dryer (ATFD) can be operated under high vacuum due to its unique technology. They are one of the most promising continuous dryers which are perfectly adaptable for multitude of materials.
Our dryers are widely used throughout the process industries to convert liquids, slurries, and pastes to free- i owing solids in continuous, single pass operation. Constant renewal of layer/i lm near the wall which helps in reducing the fouling. Our Dryers have self-cleaning heating surfaces such that the moving parts undergo minimum maintenance in the long run.
