Selecting Evaporators for Process Applications

In a falling-film evaporator, it can improve the liquid loading at the bottom of the tube, allowing higher distillate-to-feed ratios. In most cases where the feed contains solids or crystallization is present, forced circulation should be used. The advantages of using a forced-circulation evaporator are: High heat-transfer coefficients

Evaporator Types - Heat Transfer - Brewiki

Jan 06, 2022 Figure 10. Tube distributors for falling film evaporators. (Henry VogtMachine Company.) Heat transfer rates in falling film evaporators are relatively high even at low temperature differences across the liquid film; thus, these evaporators are widely used for heat sensitive products because of uniform temperatures and short residence times.

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

Types of Evaporators - Vobis LLC

Such evaporators differ from tubular evaporators mainly in the shape and form of the heating surface, which consists of an assembly or assemblies of corrugated plates. These evaporators are available in four configurations: rising/falling-film, falling-film, forced-circulation with suppressed boiling, and agitated thin-film.

Evaporator - Types Diagram Parts Working Application

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 ...
