A controlled bubble of cavitation is formed within the distilland by opposed centrifugal and centripetal forces in the plane of an afferent mesial passage. Thus a distilland surface forms around the axis of rotation, and saturated vapor is continuously stripped from this distilland surface by the work of a vapor pump, which also creates the centripetal force. The vapor vortex within this cavitation region ejects by centrifugal force whatever in it is denser than pure vapor, including any particles or droplets which may somehow become entrained in the vapor. Bubbling at the distilland surface, which might produce mist, is suppressed by centrifugal force. Vapor is compelled to follow an afferent flow path, and is scrubbed by cyclones in the afferent mesial passage. Scrubbed vapor is then withdrawn from within the distilland along the axis of rotation. No container is necessary for the distilland and no heat is added to produce evaporation. Purity of distillate in vacuum distillation is assured by cyclonic scrubbing of the vapor in the afferent mesial passage before condensation.
