An Agitated Thin Film Evaporator (ATFE) is a highly efficient device primarily used for the concentration of viscous and heat-sensitive liquids. It works by spreading the product into a thin film over a heated surface, facilitating rapid evaporation of volatile components. This equipment is crucial in various industrial processes, particularly where handling challenging fluids is necessary.

Working Principle

The ATFE employs continuous agitation through rotor blades, which helps minimize fouling on the thermal wall where residues concentrate. It consists of two primary assemblies: a cylindrical heated body and a rotor. The product is introduced above the heated zone, where it is uniformly distributed over the evaporator's inner surface by the rotor.

Advantages and Applications

The ATFE is essential in many industrial processes due to its ability to efficiently separate and concentrate various liquids and solutions. Its design is particularly beneficial for handling fluids that are difficult to process because of higher viscosity and sensitivity. It is commonly used in applications such as wastewater treatment, distillation, and deodorization

Operating Conditions

The Agitated Thin Film Evaporator can achieve temperatures up to 260°C, making it suitable for various processes involving heat-sensitive materials. The design allows the rapid evaporation of volatile components through conductive heat transfer, optimized by the high rotor tip speed which generates turbulent flow.
