A film can be achieved on the evaporator surface if the viscosity is favorable to allow a film to form or if a mechanical wiper assists in producing the film. Wiped film evaporation creates a thin film along the evaporative surface using spinning wiper blades and is typically used with highly viscous mixtures.
AutoVap falling film evaporators are USA-made, peer-reviewed, and C1D1 compliant, making them the perfect fit for any laboratory or processing facility that needs large-scale solvent recovery. They are compatible with a variety of solvents and have a low solution residence time.

Rising Film Evaporator We Offer Such Type Of Rising Film Evaporators Which Used In A Diverse Variety Of Applications. We Ensure Designs Which Are Capable Of Satisfying Our Customers.Rising Film Evaporator Is Best For Proving Excellent Performance In Terms Of Diluted Feed Streams.
A rising film evaporator In this type of evaporator, boiling takes place inside the tubes, due to heating made (usually by steam) outside the same. Submergence is therefore not desired; the creation of water vapor bubbles inside the tube creates an ascensional flow enhancing the heat transfer coefficient .
Rising Film Evaporators are often used on highly viscous products. In a rising film evaporator product liquor enters at the bottom of the tube assembly and as it heats, steam forms. The steam forces the liquid to flow upwards. At the same time the production of vapour .
Evaporator Testing. Stainless steel, vertical, long-tube evaporator with various tube diameters (1", 1.5" and 2") and tube lengths (10',15' and 20'). Unit may be operated as a recirculating long-tube falling film or as a down-flow evaporator.

The Armfield Rising Film Evaporator is a floor-standing unit, designed to provide practical training for the operation of large modern evaporator equipment in industry. This has been pulled directly from a working laboratory.The unit had originally been carried up a flight of stairs and installed into the laboratory- for this reason we had to disassemble the entire system down to the frame for .
A Rising Film Evaporator (RFE) is combination of vertical shell & tube heat exchanger and vapor- liquid separator mounted on top. The feed is given at bottom of shell & tube type heat exchanger and rises in tubes. Heat is given on the shell side by heating medium. .
A rising film or climbing film evaporator is a type of vertical long tube evaporator, which is suitable for processing large amount of evaporation and heat sensitive material or Blister solutions with higher viscosity. LEHENG is a rising film evaporator manufacture from China, we are specialized in MVR centrifugal steam compressor and evaporation system.
Apr 20, 2020 · Different evaporators come in different designs on the basis of their functioning mechanism. A thin film evaporator has an extremely complex build and design but has some primary components which facilitate distillation of highly volatile mixtures. These are made of glass or metal, more often than not stainless steel. Glass tends to be cheaper while stainless steel tends to be durable and .
Rising film & falling film evaporator having area of 0.3 m2 each Suitable for feed rate of 10-20 lit/hr Heating by hot water or thermic fluid or steam up to 300 °C Can operate under reasonable vacuum
Description Cail & Fletcher Roberts and Kestner evaporator is a rising film type. Installed in multiple effects into the evaporation station this evaporator concentrates the juice from the purification station and sends the concentrated juice (syrup) to the crystallization station.
Sep 14, 2019 · A Rising Film Evaporator (RFE) is a vertical shell and tube heat exchange with a vapor-liquid separator mounted at the top. The rising-film evaporator is the original version of the long-tube vertical evaporator. Steam condenses on the outside surfaces of the vertical tubes.
Climbing film evaporators, also known as rising film or vertical long tube evaporators, are used in industry for effluent treatment, polymer production, food production, pharmaceuticals, and solvent recovery. 1 The liquid being evaporated is fed from the bottom into long tubes and is
A Rising Film Evaporator (RFE) is a vertical shell and tube heat exchanger with a vapor – liquid separator mounted at the top. The liquid to be concentrated is fed .
Description. 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.
•Types of evaporators –Batch-type pan, natural circulation, rising-film, falling-film, rising/falling-film, forced circulation, agitated (or mechanical) thin-film •Capacity of evaporator –Mass of vapor produced (mv) •Steam economy –Ratio of vapor produced to steam utilized (mv/ms) •Energy conservation techniques –Multiple effects
The basic design of the climbing/falling film plate evaporator consists of two phases. In the climbing phase, the liquid feed is heated by a flow of steam as it rises through a corrugated plate. In the subsequent falling phase, the liquid flows downward at high velocity under gravitational force.
