A system for dispersing finely dispersed solids into high-viscosity products includes, in a container, a coaxial stirring system having stirring elements on two independently drivable, coaxially arranged shafts. A positive-displacement, close-wall-clearance stirring element on the one shaft and a plurality of stirring elements on a central shaft are arranged in such a manner that, in an upper mixing region of the container, a combination of the positive-displacement, close-wall-clearance stirring element and stirring elements for forming an ideally mixed zone is provided, and in a mixing region downstream of the upper mixing region of the container, stirring elements for developing a plug-flow zone are provided. A positive-displacement pump is provided in a region downstream of the plug flow zone as a discharge zone. |
