2011-6-6 · Wiped film evaporation (WFE) and agitated thin film evaporation are synonymous terms. It is a process of continuous evaporation whereby the process fluid is pumped into a heated evaporator device which contains rotating internal blades. These blades force the fluid into a thin film, hence the name, over the inner walls of the evaporator.
2022-4-9 · A thin-film evaporator or wiped film evaporator, there is a wiper system that is rotating at all times. This rotating system allows the product to be distributed to a film. The film is loed on a heated pipe along the inner surface. When the evaporation process is occurring, the wiping system will speed up. This allows for a mass transfer and
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 gradients exist in the liquid film, both axially and
Every Pfaudler Wiped Film Evaporator is thoroughly tested and inspected prior to shipment via Factory Acceptance Testing including a vacuum rise test, internal and jacket hydrostatic pressure test, and a operational test with water to ensure the WFE is operating precisely to our standards prior to shipment.
2022-4-10 · Wiped Film Evaporator Theory. The wiped film evaporator or agitated thin film evaporator is used for creating the shortest residence time while allowing a pressure drop configuration that is low. This ensures that product degradation does not occur while continuous and effective processing takes place while being sensitive to heat and viscosity.
Evaporator temperature (from 28 to 112 °C), condenser temperature (from −8.4 to 8.4 °C), and feed flow rate (from 8.3 to 21.7 ml/min) were the studied factors. The results showed that it is
This rotor has flexible wiper blades, which swing outwards by the centrifugal force and wipe the heated surface. Your wiped film evaporator can be made of solid or clad metallic alloys, including exotic ones, but can also consist of glass-lined …

Next Wiped Film Evaporator Next The Multiple Effect Evaporator (MEE) / Zero Liquid Discharge (ZLD) is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence …
2022-4-14 · 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
2017-9-6 · added to perform the evaporation in low pressure. There are two main types of thin film evaporators, static thin film evaporator (STFE) and agitated thin film evaporator (ATFE). (Dziak, 2011) In static film evaporator, or falling film evaporator (FFE), liquid is spread with a nozzle on the inner surface of the cylinder and it flows down the wall.
Simulation of Wiped Film Evaporator 44 IJCPE Vol.9 No. 2 (June 2008) removed from the wall and distributed into the bulk of the liquid. At the same time fresh material is being presented
2011-12-27 · CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS. Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts with a liquid
2020-4-15 · the remaining liquid is being wiped into a film on the tube surfaces resulting in good heat transfer conditions. The falling film evaporator is used to reduce the amount of heat treatment and exposure of heat to the product. The tubes are from 4 to 5 cm diameter and up to 600 cm long in the falling film evaporator. The product is sprayed or

Colburn AP. 1964 A method of correlating forced convection heat transfer data and a comparison with fluid friction.
Rotary evaporator - WikiMili, The Free Encyclopedia. A rotary evaporator (or rotavap [1] /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is …
