Zusammenfassung:Continuous process for prodn. of coated solid particles of at least one alkali metal persalt by enclosing the persalt with a coating compsn. comprises: (a) continuously crystallising a supersaturated aq. soln. of the persalt using any known technique; (b) transferring the resulting persalt particle suspension to a stirred post-crystallisation vessel, introducing at least one coating agent (I) and crystallising the (I) onto the surfaces of the persalt particles under controlled conditions of temp. and agitation; and (c) centrifuging and drying the coated particles.
