Abstract
A novel process for the complete isolation and rapid drying of a solid, or mixtures of solids, from a suspension, is described in that there is added to the aqueous or organic suspension containing said solid an additional liquid, or a mixture of such liquids, which is a solvent for the solid contained in the suspension, and which liquid is insoluble, or soluble to only a limited extent, in the suspension liquid, in such a way that a multiphase system is formed; and the mixture is maintained in a state of intense turbulence until agglomerates of the solid are formed; and this is then seperated from the multiphase system and optionally dried.
