A method and a device for gentle continuous mixing of a droplet dispersion with a liquid are described, wherein the liquid is injected into the droplet dispersion in the form of a plurality of fine liquid jets, such that the kinetic energy of the liquid jets is dissipated at a short distance from the injection point and further mixing is effected by circulating flow generated in the vessel and exhibiting shear rates of less than 20/s.

[ What is claimed is:] [1.] A device for making microcapsules by continuously mixing a liquid with a droplet dispersion, comprising a cylindrical vessel, having an axis and a vessel wall, with an axially disposed inlet for the droplet dispersion creating an inlet point, said inlet taking the form of an inlet pipe projection into the vessel such that the vessel comprises an annular space surrounding the inlet pipe to the rear of the inlet point, and a plurality of injection nozzles which open in a sectional plane of the vessel wall perpendicular to the axis and, in the through-flow direction, approximately at the level of the inlet point into the vessel, wherein said nozzles and said annular space are sized and oriented such that a droplet dispersion backflow in the annular space is divided into an axial flow and a peripheral forward flow.
