2012-10-12 · In essence, the Pfaudler Wiped Film Evaporator (WFE) is designed to continuously separate volatile compounds by introducing a mechani-cally agitated, thin film of feed material to a heated surface. The short residence time allows for efficient and reliable processing of a wide variety of high-boiling, heat-sensitive and/or viscous products.
A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface. The model concept for flow in the wiped film evaporator assumes that prior to each rotor blade a bow wave is formed.
The main component of the thin film evaporator consists of a rotor/wiper encased in a cylindrical heating jacket. The product first enters above the heated zone where it is evenly distributed against the inner wall of the heating jacket by the rotating wipers. A rotor then forms a thin turbulent layer of liquid, which creates ideal heat flux .

The thin film evaporators of De Dietrich Process Systems are made of highly corrosion resistant QVF® borosilicate glass 3.3 or De Dietrich® glass-lined steel both providing an extremely smooth surface reducing the risk of material sticking to and hence remaining and degrading on .
For the thermal separation of a mixture a thin film is produced at the heated wall of a cylindrical or conical evaporator. A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface.

2019-4-10 · The current paper reports on two modifications that have improved the design and performance of these evaporators. This plant can be used in researches in evaporation mechanism and enhancement of agitated thin-film evaporator and separation of heat sensitive and viscous materials with high purity. Fig.1 is the flow diagram of experiment plant.
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 [.]
Our Wiped Film Evaporator jacketed pressure vessels are designed and manufactured per most major worldwide pressure vessel codes. Adhering to strict rolling tolerances and a polished inner shell surface ensures excellent wiper blade performance and maximum heat transfer, leading to an optimized evaporation rate and separation.
offers 679 thin film evaporator products. About 39% of these are Evaporator, 0% are Refrigeration & Heat Exchange Parts, and 0% are Heat Exchanger. A wide variety of thin film evaporator options are available to you, such as local service location, power source, and key selling points.
In wiped film and short path evaporators, the crude material is heated up on the internal surface of a heated tube. A special rotating wiping system inside the evaporator is generating a very thin and turbulent film on the heated surface. Out of the heated and thin film, .
Agitated Thin Film Evaporator: Agitated thin film evaporator is confined mainly to the concentration of very viscous materials & heat sensitive liquids such as gelatin, antibiotics, fruit juices & solvent mixture etc. Feed is introduced at the top of evaporator & is spread by wiper blades on to the vertical cylindrical surface inside the unit.
LCI offers thin film / wiped film evaporator designs in a wide range of configurations. Rotor Designs. Fixed Clearance for all horizontal designs and most vertical applications for less viscous liquids, generally less than 50,000 cps; Wiped Film/Hinged Blade for materials with .
Thin Film Evaporators. The UIC Thin Film Evaporators normally operate within a pressure range of 1 mbar and 100 mbar. The product to be treated flows along the inside wall of the evaporator as a liquid film from the feed point to the discharge point. The residence time in the vessel is very short reducing thermal stress to a minimum.
