Falling Film Evaporator | UD Technologies

Falling Film Evaporator | UD Technologies

The liquid to be concentrated is preheated to boiling temperature if required. 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. The liquid to be evaporated is evenly distributed on the inner surface of a Glass tube.

The Essentials of Continuous Evaporation | AIChE

The Essentials of Continuous Evaporation | AIChE

Evaporation differs from dehydration and drying in that the product of evaporation is a concentrated liquid, not a solid. Evaporation can be used as the initial step in producing a dried product if the liquid concentrate then undergoes a drying process such as spray drying. The combination of evaporation and spray drying is often used to make .
