Falling film evaporators are renowned for their efficiency in industrial processes that require concentration of heat-sensitive liquids.
Heat Transfer Efficiency: Unlike conventional evaporators, falling film evaporators ensure efficient heat transfer due to the thin film of liquid flowing down the heating surface. This minimises residence time and exposure to high temperatures, crucial for preserving product quality.
Low Residence Time: Liquid flows as a thin film downward under gravity, leading to minimal residence time in the evaporator. This feature is beneficial for heat-sensitive materials, reducing thermal degradation and maintaining product integrity.
High Evaporation Rates: The continuous formation of a thin film maximises the heat transfer area and facilitates rapid evaporation. This results in high evaporation rates and throughput, making falling film evaporators ideal for large-scale production.
Energy Efficiency: By operating under vacuum conditions, falling film evaporators reduce the boiling point of the liquid. This lowers the required temperature for evaporation, leading to significant energy savings compared to other evaporation techniques.
Versatility: They can handle a wide range of viscosities and thermal sensitivities of liquids, from aqueous solutions to highly viscous substances. This versatility makes them suitable for diverse industries such as food and beverage, pharmaceuticals, chemicals, and more.
