Abstract

A process and an apparatus for the homogeneous heat treatment of a liquid which induces a helical swirling motion to the liquid to obtain a substantially homogeneous final thermal state and constant final temperature of the liquid. The liquid is moved through a vertical cylindrical tube which contains a central column and at least one perforated plate and is exposed to a microwave energy field as it moves through the tube.
