摘要

A heat and mass transfer method and apparatus in which a vertically extending conduit defines an upward flow path for a mixture of vapor and liquid. In a disclosed embodiment of a deodorizer, steam is injected into edible oil or fat and causes it to follow an extended, serpentine flow path. Since the deodorizer is operated at sub-atmospheric pressure, the steam expansion is large and promotes efficient heat and mass transfer.
