Abstract (en)

[origin: EP0570335A1] The device (1) for admixing a pourable component to a liquid based composition contains a vessel (2) which has at least one stirrer (10, 11) rotatable about a vertical axis (3). The device (1) further has a line (14) which is connected to an inlet (6a) and an outlet (8) of the vessel (2) and through which at least part of the liquid based composition is passed. During operation of the device, the pourable component, for example a pulverulent drug is admixed particulately, via a solids introduction appliance (17) arranged in the line (14), to the liquid base composition passed through the line (14). This manner of solids uptake has the advantage, compared to previously known methods, that the pourable component is dispersed relatively rapidly and uniformly in the material and that no agglomerates of solid particles are formed when this component is introduced. Moreover, the components of the material being mixed are blended optimally as a result of the fact that the material flowing back into the vessel (2) is homogenised gently by a turbulence tube (vortex tube) (18) and is dispersed uniformly in the interior (7). <IMAGE>
