Rising/Falling Film Tubular – Tubular Evaporation – Steam-Based

Industry: Fruit and Vegetables (NAICS 3114) Dairy (NAICS 3115)

NAICS process:

311411 Frozen Fruit and Vegetables

311421 Canned Fruit and Vegetables

311514 Evaporated and Condensed Milk

Process Brief: Water is removed using vacuum to draw condensate and water vapor upward and then downward inside a tube that is heated by steam on the outside.

Energy source: Steam/natural gas

Energy Intensity:

Rising/falling film tubular evaporators incorporate elements of rising and falling film designs. The first half of the main column uses a rising film design that is relatively basic. At the top of the tube bundle the product enters a falling film tube bundle. Combining the rising and falling film designs reduces the tube height by half.
