Rising-Film Evaporator

double-effect-ltv-rising-film-evaporatorThe rising-film long-tube vertical evaporator is commonly used to concentrate many non-scaling types of liquor. Liquor enters the bottom of the tubes and is heated to boiling. The expansion of the vapor carries the liquor out the top of the tube.

While this is an old design, it is still used in many applications because the system is mechanically simple with few pumps and relatively low installation and operating costs.
