Thin Film Evaporation Test Station

Thin Film Evaporation Test Station THIN FILM EVAPORATION PILOT PLANT – is a training system for the concentration of solutions, especially suitable for heat-sensitive, viscous or easily contaminated products, such as sugar, vitamin, protein solutions, fruit juices or fermentation broths. The evaporation process takes place in a cylindrical container, which is equipped with a steam heating jacket and a three-blade rotor, forming an extremely thin liquid layer on the walls.

Automated version (ESSa/EV) allows automatic control of steam flow and system vacuum via PID controller and monitoring of the process by computer.
