A falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger. In general evaporation takes place inside vertical tubes, but there are also applications where the process fluid evaporates on the outside of horizontal or vertical tubes.
MVR falling film evaporator mainly composed of preheater, heat exchanger, separator, vacuum system, MVR steam compressor, cooling system, cleaning system and control system. Products Features for LH MVR Falling Film Evaporator: Suitable evaporating process for material with high viscosity and concentration, surface film flow with minimum losses.
Falling Film Evaporator systems from Vobis are compatible with heat-sensitive products (such as natural extracts) with relatively low to medium viscosities; they have a short residence time in the tubes, and typically evaporate under vacuum conditions to lower the boiling point in order to protect heat sensitive materials.

This means that a vacuum pump or a jet ejector vacuum system on the last effect of the evaporator is required. Fig.1, Evaporator types. (a) Horizontal-tube, (b) Vertical –tube, (c) Long-tube vertical and (d) Forced circulation. . Falling Film Evaporators (FFEs) FFEs have many energy-saving, multiple-effect evaporation and mechanical vapor .
The Wiped Film Evaporator (WFE) is used for concentration, distilling, stripping, dehydration and deodorisation of products which are heat sensitive or viscous. The equipment can handle a very wide range of feed compositions ranging from 1% to over 95% concentration. WFE has several advantages as stated in the table below. The operation is continuous with [.]
Like all pulp mill unit operations, evaporators can have operating issues due to the processes occurring inside the system or due to the complex mill chemistry. Almost all these issues fall into six main categories including scaling, corrosion, liquor carry-over, vacuum .
Description: 9400 kg/hour evaporation (20723 lbs/hour) 316Ti stainless steel (1.4571) single effect falling film evaporator, consisting of (1) 68.7 square meter 316Ti stainless steel (1.4571) tube, head and shell vertical falling film.
Falling film evaporation is to add the material liquid from the upper box of the heating chamber of the falling film evaporator, and evenly distribute it into each heat exchange tube through the liquid distribution and film forming device. Under the action of gravity and vacuum induction and airflow, it becomes a uniform film. Flow from top to bottom.
Falling film evaporator. This type of evaporator is generally made of 4–8 m (13–26 ft) tubes enclosed by steam jackets. The uniform distribution of the solution is important when using this type of evaporator. . In recent years, multiple-effect vacuum evaporator (with heatpump) systems have come into use.
falling film evaporator basics This product is widely used in the concentration of chemical, ketchup, glucose, starch sugar, oligosaccharide, caramel, sorbitol, fresh milk, fruit juice, vitamin C, maltodextrin, pharmaceutical and other aqueous solutions.
Falling film evaporators are largely used to remove a solvent from a liquid mixture by evaporating the more volatile component. Compared to wiped film evaporators, falling film evaporators: have a higher heated surface area per footprint, are less equipped to distill highly viscous mixtures, and are much better equipped to distill a solvent at .
Falling Film Evaporator Operation. Falling Film Evaporators offer distinct operating advantages in the concentration of many materials, such as certain food products, fruit juices, pharmaceuticals and similar materials, which are particularly suited to evaporation in this type of equipment.
The heat transfer surface may be the internal wall of tubes (climbing or falling film tubular evaporators), the plates of a plate heat exchanger (plate evaporators), or a rotating conical surface (Centritherm evaporator). The boiling film is moved by gravity, centrifugal force, or mechanical agitation, in addition to the dragging effect of the .
