Rising Film Evaporator

Mathesis Engineers Rising Film Evaporators deliver efficient evaporation through natural circulation, providing excellent heat transfer, low steam consumption, and consistent product quality. Designed for low-viscosity, non-scaling, and non-crystallizing liquids, these systems ensure reliable continuous operation with minimal maintenance. They are widely used in sugar, chemical, fertilizer, and specialty process industries where high thermal efficiency and economical operation are essential.

Product Details

A Rising Film Evaporator consists of a vertical tube bundle where the liquid feed enters from the bottom. As steam heats the tubes, the liquid begins to boil inside the tubes, generating vapor bubbles. These bubbles rise rapidly and create a lifting action that carries the liquid upward along the inner tube walls as a thin film.

During this upward movement, continuous evaporation takes place. At the top of the evaporator, the vapor is separated from the concentrated liquid inside a vapor separator. The concentrated product is collected for further processing while the vapor can be condensed or reused for improved energy efficiency. The natural circulation design eliminates the need for high-capacity circulation pumps, resulting in lower operating costs and simplified maintenance.
