Device for treating substances in different phases, such as the treatment of substances in liquid, semi-liquid or paste form, by another notably gaseous phase

摘要

A device and process for the treatment of materials in different phases, one material being in a fluid phase and another in a gaseous phase, wherein the material in fluid phase is introduced as a stream within the axis of the gaseous phase in helicoidal flow for subsequent passage through a confined zone whereas a substance to be treated is introduced at the level of the smallest section of the confined zone.
