Falling Film Evaporator
A falling film evaporator is a type of heat exchanger widely used in various industries for the concentration of solutions. It operates on the principle of a thin film of liquid flowing down a heated surface, allowing for efficient heat transfer and vaporization.
In a falling film evaporator, the liquid to be concentrated is typically distributed as a thin film onto the surface of vertical or inclined tubes or plates. As the liquid film flows downward, it is heated by the surrounding vapor or a heating medium inside the tubes. The heat causes the liquid to evaporate, and the concentrated product is collected at the bottom, while the vapor is typically removed at the top
Product Feature
Advantages of Falling Film Evaporator:
- High Heat Transfer Coefficient: The thin film ensures efficient heat transfer, leading to quick evaporation.
- Energy Efficiency: Falling film evaporators are known for their energy efficiency due to the continuous replenishment of the liquid film.
- Low Residence Time: The short residence time of the liquid on the heat exchange surface minimizes the risk of product degradation.
- Compact Design: Generally, falling film evaporators have a compact design compared to other evaporators.
Product Application
Industrial Applications:
- Food and Beverage Industry: Used for concentrating fruit juices, dairy products, and other liquid food items.
- Pharmaceuticals: Applied in the production of pharmaceutical intermediates and drug formulations.
- Chemical Industry: Utilized for the concentration of various chemical solutions, acids, and organic compounds.
- Desalination: Falling film evaporators are used in multiple-effect distillation for desalination
