Falling Film Evaporator - Principle Construction And Working

Falling Film Evaporator - Principle Construction And Working

Apr 16, 2022 Advantages: A falling film evaporator is suitable for high viscous liquids because the flow of vapour film is assisted by gravity. The liquid hold-up is less and the hold-up time is very small. The liquid is not overheated during passage and heat transfer coefficients are high even at low boiling ...

Falling Film Tubular Evaporator Thermal Kinetics

Falling Film Tubular Evaporator Thermal Kinetics

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...

USIPL - Falling Film Evaporators

In Falling Film evaporators, juice usually enters from the top. It is evenly distributed into the heating tubes. Thin film enters the heating tube and it flows downwards at boiling temperature. In the process, it is partially evaporated. Steam enters in the jacket through slots in calandria. Juice and vapor both flows downward in a parallel flow.
