Abstract
Heat-sensitive, foamable liquids such as latex, are concentrated in a continuous process without foaming by feeding a heated liquid to a tubular evaporation chamber maintained at a reduced pressure where the liquid is adiabatically vaporized and forms an annularly flowing two-phase stream. The liquid and vapor phases are largely separated in the evaporation chamber by centrifugal forces acting on the stream. The final separation and isolation of the liquid phase is achieved in a separator consisting of a cyclone separator, a reservoir for the concentrated liquid and a settling chamber.
