The gassing device (3; 3?) is designed in such a manner that until a critical gas quantity value determining the flooding point is reached, the gassing device (3; 3?) supplies the quantity of gas to the stirring element (2) from below and when the flooding point is exceeded, the gassing device (3; 3?) simultaneously supplies the gas exceeding the flooding point at the side(s) of the stirring element (2). The aim of the invention is to prevent the stirring element (2) from being flooded and to improve the dispersing effect of the liquid and gas.
