Thin Film and Wiped Film Evaporators. An LCI agitated thin film evaporator (TFE) or wiped film evaporator (WFE or "wiffe") provides short residence time and open, low pressure drop configuration, allowing continuous, reliable processing of many heat sensitive, viscous, or fouling materials without product degradation.

Agitated thin film evaporators Agitated thin-film evaporation has been very successful with difficult-to-handle products. Simply stated, the method quickly separates the volatile from the less volatile components using indirect heat transfer and mechanical agitation of the flowing product film under controlled conditions.
'The plant is equipped to recycle used lubricants with near zero waste with its use of sophisticated green technology capabilities, including 'wiped thin film evaporator ' under high vacuum,' said group vice-president K A Padmanaban.
The chemical treatment is needed to prevent the ing and the tendency for scale formation in the evaporator. Both factors may seriously impair unit operation. Within the evaporator, the feed water is sprayed at the top where it falls in the form of thin film down the succeeding rows of tubes arranged horizontally.
Answer: I assume you are referring to thick and thin film technology in electronic applications. In thick film a resistive paste consisting of a mixture of metal oxides, a carrier and a binder is deposited (usually printed) on a flat substrate. The conductor (track) material is a granular film o...
In process engineering, an evaporator is an apparatus for converting a liquid into its vaporous state. A wide variety of evaporators are used industrially. For example the Robert evaporator in the sugar industry or the thin-film evaporator for evaporating food concentrates or pharmaceutical solutions. To reduce costs, it is common to connect several evaporators in series.
Thermal evaporation is a well-known method for coating a thin layer in which the source material evaporates in a vacuum due to high temperature heating, which facilitates the vapor particles moving and directly reaching a substrate where these vapors again change to a solid state. In this method, a charge holding boat or resistive coil is used in the form of a powder or solid bar.
Evaporation is a form of physical vapor deposition in which a target material is heated in high vacuum. The heated target material will then melt and evaporate or sublime to transform into the gaseous phase. These atoms then precipitate into solid form, coating everything in the vacuum chamber (within line of sight) with a thin layer of the target material.
The Sharon is a cryo-pumped thin film evaporator with a Temescal four hearth 270° bent electron beam evaporation source. The system incorporates a Commonwealth Scientific Corp. ion source for in-situ sample cleaning. Fixturing in the Sharon will …
The Cooke Evaporator is an electron beam evaporator used to deposit Ni, NiCr, Au, Ag, Cu, In, Pd, Sn and Zn. It is hoist-lifted domed coater with a single-wafer holder. All the e-beam evaporators in the LNF are setup using small point sources and long throw distances that lead to very directional deposition with minimal heat transfer.
If you want to make thin or thick films by conventional evaporator (thermal evaporation) you need to know: 1-The acoustic impedance value and density to measure the thickness of the produced film ...
A horizontal Agitated Thin Film Dryer (ATFD-H) has a centrally located rotor having closely fitting blades. It rotates in a precision-machined jacketed shell. The feed in the form of solution, slurry or wet cake is converted into a thin film, which is intensely agitated due to action of the high-speed rotor.
This is a thin-film evaporation under reduced pressure down to 0,001 mbar. In this type of distillation system the condenser is integrated in the centre of the evaporator. The distance between evaporation surface and condenser is extremely short and pressure losses are eliminated. Film evaporation at reduced pressures of 0,001 mbar is also ...
Physical vapor deposition (PVD) is a type of deposition where source materials are transformed into a vapor or plasma using a physical process (typically heating or bombardment.) The vapor then moves towards a substrate where it condenses on the surface. More details: LNF Tech Talks, video recording and complete slides are available.
Evaporation is a common method of thin-film deposition. The source material is evaporated in a vacuum. The vacuum allows vapor particles to travel directly to the target object (substrate), where they condense back to a solid state. Evaporation is used in microfabrication, and to make macro-scale products such as metallized plastic film.
Thin-Film Evaporation Processes. Milton Ohring, in Materials Science of Thin Films (Second Edition), 2002. 3.4.2.3 Modification of Films. Lastly we briefly consider two additional issues related to the modification of film properties induced by e-beam evaporation. The first concerns evaporant ion bombardment of the growing film.

A climbing/falling film plate evaporator is a specialized type of evaporator in which a thin film of liquid is passed over a rising and falling plate to allow the evaporation process to occur. It is an extension of the falling film evaporator, and has application in any field where the liquid to be evaporated cannot withstand extended exposure ...
Thin-film memory is a high-speed alternative to core memory developed by Sperry Rand in a government-funded research project.. Instead of threading individual ferrite cores on wires, thin-film memory consisted of 4 micrometre thick dots of permalloy, an iron-nickel alloy, deposited on small glass plates by vacuum evaporation techniques and a mask. The drive and sense lines were then added ...
Rising film evaporator Last updated September 29, 2019. A rising film or vertical long tube evaporator is a type of evaporator that is essentially a vertical shell and tube heat exchanger. The liquid being evaporated is fed from the bottom into long tubes and heated with steam condensing on the outside of the tube from the shell side.
The thin or wiped film evaporator is the ideal apparatus for a continuous evaporation process of your heat-sensitive, viscous and fouling products. This rotor has several rigid blades that have a fixed and well-defined clearance from the wall of the shell.
Basically, it involves applying a thin coating to another surface, usually by coaxing the coating material from a vaporous or dissolved state using electricity, high heat, chemical reactions, evaporation, or other techniques. One of the most common (and oldest) types of thin-film deposition is electroplating. Here, the target object (such as a ...
Horizontal evaporation without losing film integrity. The VTA horizontal thin film evaporator allows you to vary the required residence time within wide ranges. The product is distributed at the heated evaporator wall by the rotor so that a turbulent circular ring forms at the whole evaporator surface.

Thin-film solar cells are cheaper than traditional solar cells that are made from crystalline silicon. On the other hand, thin-film cells, for example, CdTe-based solar cells need far less raw material (up to 100 times less), and lesser manufacturing cost than silicon cells. Thin-film cells also absorb sunlight at nearly the ideal wavelength.
