Evaporator design In an evaporator, sugar juices are concentrated by water evaporation. The heating medium in this process is heat-ing steam. The produced vapour is put to use again in other evaporators or steam-consuming equipment. BMA’s falling-film evaporators have been specifically de-signed for this task, with major criteria a small ...

Film Evaporation Technology - Sulzer

Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the

Evaporator System Basics - Dupps

Falling Film Evaporator Like the rising film evaporator, the heat exchanger in a falling film evaporator is vertically mounted. In this case, however, evaporator liquid is pumped to the top of the heat exchanger and flows in a downward direction through the tubes. Boiling of water in the evaporator liquid occurs as the liquid

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 ...

How they Work Falling Film Evaporators Aptia Engineering

Oct 09, 2019 The process fluid is passed through the tube side of the evaporator. Energy is transferred from the heating media into the product, and a portion of the product is vaporized. The process liquid is pumped into the top of the falling film evaporator and is distributed evenly across all of the heating tubes in the heat exchanger.

White Paper: Evaporator Issues and Technology

Oct 31, 2018 Evaporators fall into a few categories, based on how they operate: rising film (RF) evaporators, falling film (FF) evaporators and forced circulation (FC) evaporators. In addition, all these types of evaporators can be classified as a concentrator whenever they operate above the solubility limit for one of the various salt
