Natural circulation evaporator for high temperature products

In industries such as food processing or chemicals, efficiently concentrating products with high evaporation ratios while handling substances prone to fouling can be challenging. Managing these processes requires equipment capable of reducing both viscosity and fouling tendencies through effective heat transfer and circulation.

Achieve high concentration with minimal fouling.

The Natural Circulation Evaporator by GEA is designed for products that are insensitive to high temperatures but require large evaporation ratios. It features a vertical shell-and-tube heat exchanger with short tubes and a lateral separator at the top, ensuring a quick start-up and large specific capacity. This evaporator’s distinct design minimizes liquid content due to the short length and small diameter of the heating tubes, promoting efficient heat transfer and evaporation using the thermosiphon or rising film principle. The system also includes options for traditional live steam heating or utilizing waste heat, depending on energy availability. By incorporating divided boiling chambers with individual liquid circulation systems, the heat transfer rates are optimized, and the required heating surface is reduced significantly, making it suitable for various applications in food processing, chemical, and other industries.
