Agitated Thin Film Evaporator (ATFE) | Wiped Film Evaporator

“Our high viscosity units can handle products with viscosities of several million centipoise!”

An Agitated Thin Film Evaporator (ATFE), also known as Thin Film Evaporator (TFE) or Wiped Film Evaporator (WFE), consists of a jacketed shell precision machined from inside and a rotor having blades that maintain a close clearance from the shell.

A feed distributor at the entry point distributes the liquid in a thin film on the heated wall. The high speed rotor further spreads and intensely agitates the film as it flows down. The generated vapors flow counter currently and get cleaned by an integrally mounted entrainment separator.

FEATURES

Residence time of a few seconds with a narrow spread, an important feature for heat sensitive products
Required evaporation is achieved in a single pass, avoiding product recirculation and possible degradation
Scale formation on the heat transfer surface is reduced due to the intense agitation of the liquid film
Excellent turn down capability
Low product holdup, ideal for hazardous applications
Operating pressure as low as 1 mbar and operating temperature up to 400 ⁰C
Special designs for clean room applications and GMP requirements
