Abstract
Process for effecting rapid and homogenous intimate contact of substances which occur in different phases. The process includes a step of producing contact between a helicoidal flow of substances, at least partially in the gaseous state, and a rectilinear flow which is coaxial with the first flow, of liquid or solid substances, at the outlet of a flow passage having a downstream constricted aperture, the amount of movement of the helicoidal flow at the outlet being at least 100 times greater than that of the rectilinear flow. This process can be used in particular for producing mixtures or for drying substances.
