Forced circulation evaporator for highly viscous liquids

Optimize energy efficiency and minimize fouling in your evaporation processes with a forced circulation evaporator designed for precise handling of highly viscous and temperature-sensitive liquids.

Evaporates and Crystallizes High Viscosity Liquids

The Forced Circulation Evaporator from GEA is designed to expertly handle the challenges of evaporating and crystallizing highly viscous liquids or those prone to fouling. By utilizing a shell-and-tube or plate heat exchanger calandria with a flash/vessel separator, the equipment minimizes fouling as boiling occurs in the separator rather than on the heating surfaces. This evaporator is ideal for crafting products like salt, corn syrup, and juice concentrates, and is particularly suited for applications in food, chemical, and pharmaceutical industries. It provides seamless integration into multiple-effect evaporation plants, enhancing throughput with its continuous, high-speed operation. Equipped with a circulation pump, it enables precise control of flow velocity and liquid temperature, optimizing energy efficiency by leveraging both live steam and waste heat. Available in various material options to ensure durability and chemical compatibility, the system also supports compliance with industry standards like GMP and FDA, featuring an optional CIP system for efficient cleaning. GEA offers tailored design options to match specific product specifications and production requirements, backed by comprehensive engineering support.
