Abstract

A process and a system for drying a solution, a slurry or a solid suspension of a material non-sensitive to heat is disclosed. A spray of finely divided particles is formed in a chamber and a plasma of superheated steam is used as the heat source for drying the particles as they pass through the chamber. The resulting product is removed from the chamber in the form of a suspension of dry particles in superheated steam.
