May 08, 2015· FALLING FILM EVAPORATOR 2. 2 The Falling Film Evaporators can be operated with very low temperature differences between the heating media and the boiling liquid, and they also have very short product contact times, typically just a few seconds per pass.
Wiped Film Evaporator Our wiped film evaporator is the ideal apparatus, if you need a continuous pr ocessing of your heat-sensitive, viscous and/ or fouling products Design Our wiped film evaporator consists - in contrast to a falling film evaporator – of merely one single evaporation tube fitted with a mechanical rotating device, the so-

Dec 20, 2014· Agitated film evaporator Main resistance of the heat transfer is on evaporator side Heat transfer coefficient and turbulence is increased by mechanical agitation of this liquid film Modifying falling film evaporator with a single large jacketed tube containing internal agitator Used for viscous fluids,high sensitive materials like rubber .
Falling film evaporators are therefore used in clean, non-precipitating liquids. A typical application, in chemical industry, is for concentration of caustic soda. Falling film evaporators versus flooded evaporators. Falling film evaporators have a number of advantages over their flooded evaporator …

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.
