Abstract (en)
[origin: WO0156687A1] According to a new partial stream method, different reagents (I, II) may be mixed quickly and intensively, especially for the production of emulsions, in a dispersing apparatus (10) which has a rotor/stator system (40, 50) at a container (B) near the bottom. A hot initial product, e.g. containing wax, may be dispersed with a dosed partial stream (R I') of a cold carrier in a premixing chamber (60) via a feeding device (30, 38) below the rotor (50). The resulting mixture is then remixed with a cold main stream (R I) or a part hereof (R I'') fed from above. Contrary to the dispersing systems known, wherein mixing and shearing of the components is performed simultaneously in the region of maximum shearing gradient, the method of the invention separates both time and location of mixing and shearing by feeding said components into the premixing chamber (60). The basic principle is that an optimum emulsion be obtained by preparing a homogeneous phase mixture first.
