For complete wetting it is important that a suitable distribution system is selected for the head of the evaporator. Wetting rates are increased by using longer heating tubes,

Film Evaporator - an overview | ScienceDirect Topics

9.1.3 Wiped falling film short path distillation. A wiped falling film short path unit is similar in design to a wiped falling film evaporator, but where the short path unit has a condenser placed at the center upon which the vapor condenses, whilst the evaporator unit does not. In a standard falling film unit, temperature and concentration

Falling-film evaporator - BMA

Falling-film evaporators from BMA used in cane sugar factories have a higher juice distributor dome, making them easier to inspect and clean. Whenever necessary, the juice distributor and heating tubes can be cleaned with a high-pressure water jet from the top tube plate, without opening the flange.
