Agitated Thin Film Evaporators (ATFE)

Mathesis Engineers Agitated Thin Film Evaporators (ATFE) are designed for the efficient evaporation and concentration of highly viscous, heat-sensitive, sticky, and fouling products. Utilizing a high-speed rotor with precision-engineered wiper blades, these systems continuously spread the product into a thin film over the heated surface, ensuring rapid heat transfer, short residence times, and superior product quality.

Product Details

An Agitated Thin Film Evaporator (ATFE) consists of a vertically mounted heated cylindrical shell equipped with a high-speed rotor and specially designed wiping blades. The feed enters from the top and is uniformly distributed as a thin film over the heated inner wall by the rotating blades.

The continuous wiping action promotes excellent heat transfer while preventing product buildup, scaling, and fouling. Under vacuum operation, the volatile components evaporate rapidly at lower temperatures, making the system ideal for processing heat-sensitive materials. The vapor is separated and condensed, while the concentrated product is discharged continuously from the bottom.

ATFE systems are widely used for solvent recovery, product concentration, and the processing of high-viscosity materials that are difficult to handle using conventional evaporators.
FEATURES & BENEFITS

Agitated Thin Film Evaporators (ATFE) Features & Benefits

FeatureBenefit
Excellent Heat TransferRotating wiper blades continuously renew the thin liquid film, providing superior heat transfer and efficient evaporation.
Short Residence TimeRapid evaporation minimizes thermal exposure, preserving product quality and preventing degradation.
Handles High-Viscosity & Fouling ProductsDesigned to process sticky, viscous, crystallizing, and fouling materials with reliable performance.
Continuous Self-Cleaning OperationThe wiping mechanism continuously removes product from the heated surface, reducing fouling and minimizing maintenance.
Vacuum OperationOperates efficiently under vacuum, allowing low-temperature evaporation for heat-sensitive and high-value products.
