Furthermore, this sort of evaporator may readily accommodate foaming product vapor separators, which are commonly accessible. Ineffective performance. While rising film evaporators are relatively efficient and offer a number of benefits, some research shows that they are not as efficient as vertical or horizontal tube falling film evaporators.
In falling film evaporators, liquid enters the top of the unit and forms a continuous film that flows down the inside of heating tubes via gravitational force. The liquid film flows downward through the tubes at boiling point. The liquid partially evaporates, concentrating the liquid. Falling film evaporators are ideal for heat-sensitive ...

The function of the evaporator is to absorb the heat from the space or surrounding medium which is to be cooled by means of refrigeration. The process of heat removal from the substance to be cooled or refrigerated is done in the evaporator. The liquid refrigerant is vaporized inside the evaporator (coil or shell) in order to remove heat from a ...
There are two main types of long-tube vertical evaporators: climbing-film and falling-film. In both types feed enters the evaporators through tubes, is heated and part of it evaporates. The vapor is then recovered. In climbing film evaporators the liquid enters from the bottom, while in falling film types it enters from the top.
