The invention relates to a sparging mixer having a rotatable hollow shaft (12) and at least one hollow mixing device (14) arranged thereon, whose cavity communicates with the hollow shaft and has orifices (18,20) towards the liquid to be sparged. In order to achieve the objective of further development of a sparging mixer of this type in such a way that, on the one hand efficient sparging of liquids and thus an improved mass transfer is achieved, and that on the other hand the design should be as simple as possible, the mixing device has at least one blade (22) inducing a flow. In addition, the orifices are arranged in the region where the run-off flow is directed outwards. |
