Abstract
A method of concentrating or evaporating water from water-containing liquids in a falling-stream or falling-film evaporator through which the liquid is caused to pass downwardly through ribbed tubes which are heated externally. The material to be evaporated is distributed uniformly to the evaporator tubes and driving steam is simultaneously introduced into the latter at a velocity so controlled with respect to the pressure that turbulence develops at the inlet to the tubes. The mixture of the material to be evaporated and drive steam is caused to rotate about the longitudinal axis of the evaporator tubes as the mixture traverses same and the concentrated product is separated from the steam and product vapors at the outlet end of the tubes.
