Rising film evaporator for concentration of viscous liquids
Effortlessly concentrate low-to-medium fouling and highly viscous liquids with this compact evaporator, optimizing space and energy efficiency in your production line without requiring extensive installations.
Concentrates and Evaporates Viscous Liquids
The AlfaVap rising film plate evaporator from Alfa Laval offers a compact solution for processing low-to-medium fouling and highly viscous liquids across several industries, including food and beverage, biofuels, and chemicals. This evaporator operates by allowing liquid to rise along heated plates, promoting efficient evaporation and concentration. With applications ranging from corn syrup to lactic acid production, it leverages multi-effect operation and recompression to minimize steam use, enhancing energy efficiency. The evaporator’s design ensures fast start-up and shutdown, ideal for heat-sensitive products. Capable of automating and adapting to existing systems with its PLC controls, the AlfaVap supports continuous operations, reducing downtime through self-cleaning properties. Its stainless steel construction offers excellent corrosion resistance, while pre-assembled configurations reduce on-site installation time, offering a quick turnaround. Optional customization and engineering support are available to meet specific processing needs.
