Agitated Thin Film Evaporator / Dryer - ATFE / ATFD

Thin film evaporator is a vertical cylindrical shell enclosed in an heating jacket with an internal rotor distributing a thin layer of oil on the heated wall, by means of rotating blades. By the action of rotor (electrically driven) high turbulence and back mixing occur in structural features of the scraper type wiped film evaporator . Motor and speed reducer. It is the driving unit for rotor rotation. The rotating speed of rotor depends on the form of scraper, material viscosity and inside diameter of evaporating cylinder.

Agitated Thin Film Evaporator - Shachi Engineering

In a horizontal thin film evaporator, the product is distributed at the heated evaporator wall by the rotor so that a turbulent circular ring forms at the whole evaporator surface. Loss of film integrity, as it can occur at strongly reduced feedrates in falling film evaporators but also in vertical thin film evaporators, is not possible in horizontal thin film evaporators. The speed of the motor of the thin film evaporator and the rotor of the slower machine will depend on the mode of the scraper. The viscosity of the material and the inner diameter of the evaporation tube; choosing a suitable linear speed of the scraper will ensure the stable and reliable operation of the evaporator and the desired evaporation effect.

The LCI agitated thin film evaporator (also commonly referred to as a "wiped film evaporator") consists of two major assemblies: a cylindrical heated body and a rotor. Product is introduced above the heated zone and is evenly distributed over the evaporator's inner surface by the rotor. The thin-film evaporator consists of a cylindrical, mechanically precisely machined heating surface with external heating and an internal rotor. The substance mixture is distributed over the circumference of the head by means of a rotating distributor system and flows downwards on an evaporator wall heated from the outside with steam or thermal oil.

Feed material is metered into the thin-film evaporator at a steadily controlled rate by an LCI or Customer supplied feed system suitable for the particular feed material. Upon entering the evaporator, the feed is immediately distributed onto the thermal wall, by the spinning rotor, as an agitated, thin liquid film. 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.

Agitated thin film evaporators are typically used for fluids which are difficult to handle due to higher sensitivity and viscosity. Such an evaporator consists of tow key components: a jacketed shell and a rotor which rotates at high speed inside the shell. Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the
