A process for drying solid residues obtained in filtration processes, in which the residue is first dried by passing a gas through it while it is still on the filter elements, and then whirl drying the residue in a lower portion of the reaction vessel. A system in which the drying gas is circulated is described. This results in a process which permits the preparation of dry filter residues which are easily transportable and avoids problems of separation from the filter elements while still wet.
