The invention describes a stirring device made from a gassing stirrer and a liquid mixer or two liquid mixers, which are arranged on a shaft and each have a feed and at least one exit opening, wherein the exit openings of the gassing stirrer and of the liquid mixer or the liquid mixers are at a distance from one another, the ratio, a/d, of the distance, a, between the exit openings to the diameter, d, of the gassing stirrer or liquid mixer being 0.02 to 0.5 and the ratio, b/d, of the distance, b, between the outer edges to the diameter, d, of the gassing stirrer or liquid mixer being 0.01 to 0.4.
A stirring device comprising a gassing stirrer and a liquid mixer or two liquid mixers, arranged on a shaft having a feed and at least one exit opening, wherein the exit openings of the stirrer and of the mixer or of the mixers are at a distance from one another, such that a ratio, a/d, of distance, a, between the exit openings to diameter, d, of the stirrer and mixer or the mixers is about 0.02 to about 0.5 and aratio, b/d, of distance, b, between outer edges to diameter, d, of the stirrer or the mixer is about 0.01 to about 0.4.
