Thin Film Evaporator How It Works LCI Corp

The LCI agitated thin film evaporator (also commonly referred to as a "wiped film evaporator") consists of two major assemblies: a cylindrical heated body and a rotor. Product is introduced above the heated zone and is evenly distributed over the evaporator's inner surface by the rotor. As the product spirals down the wall, the high rotor tip speed generates highly turbulent flow resulting in

CHAPTER 21: EVAPORATION PRINCIPLES, TYPES OF EVAPORATORS

An even thin film enters the heating tubes via a distribution device in the head of the evaporator, flows downward at boiling temperature, and is partially evaporated. This gravity-induced downward movement is increasingly augmented by the co-current vapor flow. Falling film evaporators can be operated with very low temperature differences between the heating media and the boiling liquid, and

Falling film evaporator

Falling film evaporators versus flooded evaporators Falling film evaporators have a number of advantages over their flooded evaporator counterparts. They require a lower charge, as the entire shell (in the case of horizontal evaporators) or all the tubes (in the case of a vertical evaporator) need not be filled with liquid as a thin film is now used to cover the surfaces.
