A process for producing granules comprising one or more complexing agent salts of the general formula in which R' is hydrogen or one of the groups where R'' is hydrogen, a C 1 -C 12 -alkyl radical or a -(CH 2) q -COOM radical where q = 1 to 5 n and m are in each case an integer from 0 to 5 and R''' is hydrogen or a C 1 -C 12 -alkyl radical or a C 2 -C 12 -alkenyl radical, which may be additionally substituted with up to 5 hydroxyl groups, or is one of the groups in which o and p are in each case an integer from 0 to 5, and M, independently of the others, is hydrogen, alkali metal, alkaline earth metal, ammonium or substituted ammonium in the corresponding stoichiometric amounts, - from an aqueous starting solution comprising the one or more complexing agent salts in a concentration of from 10 to 80% by weight, based on the total weight of the aqueous starting solution, in a jet apparatus, in which a gaseous driving jet positioned centrally and directed from bottom to top, or one or more gaseous driving jets positioned in the region of the central axis of the jet apparatus induce an internal loop motion, with formation of a jet zone, joined to the upper end of which is a fountain zone, which merges into a return zone in the wall region of the jet apparatus, which return zone in turn, in its lower region, merges into the jet zone, where the aqueous starting solution is sprayed into the one or more gaseous driving jets and in so doing is dried to give the granules, which are discharged from the jet apparatus.
