Manufactured by Hebeler Process Solutions, USA Falling Film Evaporators offer distinct operating advantages to concentrate many materials, such as certain food products, fruit juices, pharmaceuticals and similar materials, which are particularly suited to evaporation in this type of equipment. The plate heat exchanger can be adapted to act as an evaporator and this also applies to the Plate-fin Heat Exchanger. Buflovak Atmospheric Cooling Drum Flaker. Buflovak Vacuum Pan and Kettle Dryers. Instant and concentrated cooking ingredients such as pasta sauce, chicken broth, vegetable purees etc. Climbing Film Evaporator. Hemisphere Publishing Corporation, New York. If you prefer, we can provide you with mobile test equipment on a rental basis to apply in tests at your own facilities.

  • A climbing/falling film plate evaporator is a specialized type of evaporator in which a thin film of. The flow of the thin liquid film in the falling film evaporator is possible in two ways: cocurrent and countercurrent. It is cocurrent if the vapor is. Evaporators may be classified into falling film evaporators (in which If countercurrent flow is used, then there is a limit on the vapor velocity.

    Falling Film Evaporators offer distinct operating advantages to concentrate many Can be configured as a counter current falling film for stripping application.
    Languages Add links. This evaporator will discharge vapor as the condensate as vapor pass through more rapidly than the liquid flows in the tube. There are several problems related to climbing and falling film plate evaporators. The dilute liquid is fed to the top of the tubes,which flows downward as evaporation occurs.

    The best way to reduce energy consumption is by using multiple-effect evaporators.

    Such evaporators are really a subclass of boiling systems in general, and the heat transfer processes are those described in the article on Forced Convection Boiling.

    Then the mixture that contains liquid and vapour are discharged and it is reallocated at the top of falling film pass tubes. There are several design variations that are commonly used in industrial field.

    The steam follows a co-current, counter-current path in.
    Show all. Journal of Crystal Growth. Besides that, small liquid content in the tube can minimize the foaming problem.

    Hemisphere Publishing Corporation, New York. Although they are relatively less sensitive to heat, evaporating them at low temperature and short residence time is crucial to maintain the quality taste, texture appearance and nutritional value.

    Instant and concentrated cooking ingredients such as pasta sauce, chicken broth, vegetable purees etc. Short residence time can be achieved by higher liquid flow rates down the tube in the falling film evaporator. Liquids too viscous for natural circulation Liquids where retention time must be minimized Heat-sensitive liquids or when excess temperature is critical Liquids requiring limited temperature difference.

    A surface condenser is used to condense the vapor that produced in the second effect process.

    NJZ type countercurrent falling film evaporator concentrates (three- effect),NJZ型 逆流降膜浓缩蒸发器(三效) 产品结构 本机采用三效逆流降膜浓缩蒸发工艺,由三台. The cost-effective falling film evaporator is the most commonly used type of This separator is not required in counter-current applications (for.

    Although previously neglected in studies of mode transition, a countercurrent Li [29] studied the heat transfer characteristics of falling film evaporation on.

    It can also increase the concentration of the components in the liquid. Falling Film Evaporator Application Examples. San Diego: Elsevier. Minimizing residence time is important in order to minimize the occurrence of chemical reactions between the feed and the evaporator materials, thus reducing fouling within the evaporator.

    Falling Film Evaporators. Our distribution is a two-stage system, featuring high accuracy and a wide operating range.

    To improve the product quality, short heat contact period from single pass operation can minimize product deterioration.

    Evaporation via climbing and falling film plate design can minimize the effect of protein denaturation and thus, optimizing the product quality.

    Thermocompression is useful whenever evaporator energy requirements need to be reduced. A convenient way of providing the hot gas is to use a submerged combustion system in which the hot gas is produced in situ by the combustion of gas or fuel oil in a combustion chamber mounted in the center of the vessel containing the liquid.

    There are several process characteristics that should be taken into account in order for the evaporator to operate at its best performance.

    1. This could be achieved by compressing and recycling the vapor from a single-effects evaporator into the same evaporator as the heating medium.

    2. Other protein-rich products such as whey powder in dietary supplement and milk including both skim and whole milk are concentrated to remove most liquid components for further processes.
