ABSTRACT:
Method and apparatus for distilling a liquid mixture to separate a volatile vapor fraction therefrom. The liquid is forced to flow along a meander-like path through a plurality of concentrically arranged chambers of a rotating drum. In the radially outermost chamber, a heating unit is provided which brings the liquid to a boiling temperature to allow formation of vapor. The liquid thus freed of volatile constituents is then discharged from the outermost chamber in which the liquid is subjected to a maximum centrifugal acceleration while the vapor moves radially inwardly under the action of the centripetal force to the innermost chamber from where the vapor containing volatile constituents is discharged.
