Falling Film Evaporator (FFE)

At SRP Engineering and Tech, we offer cutting-edge Falling Film Evaporators (FFE) designed for high-efficiency evaporation of heat-sensitive and challenging liquids. The FFE system works by distributing the liquid to be concentrated over vertical tubes, where it forms a thin film that falls under gravity. The liquid is then heated by steam or other heating fluids as it travels down the length of the tubes, causing the water or solvent to evaporate. This process ensures that your products are treated gently while maintaining excellent heat transfer efficiency.

The Falling Film Evaporator (FFE) is ideal for quick and uniform evaporation, making it suitable for a wide range of industries, including pharmaceuticals, food and beverage, chemical processing, and more. The system’s ability to handle heat-sensitive liquids while providing fast evaporation and high efficiency has made it a preferred choice for many industries worldwide.

In a Falling Film Evaporator (FFE), the liquid to be concentrated is evenly distributed across vertical tubes. As the liquid flows down the length of the tube under gravity, it forms a thin film that maximizes the surface area for heat exchange. The liquid film is heated by steam or other fluids, causing the low boiler solvent or water to evaporate, leaving behind the concentrated product. This design minimizes the risk of thermal degradation of the product and promotes rapid evaporation.
