  • Patent number: 10406491
    Abstract: A system structure of an impeller for a dispersion-emulsion apparatus based on dual rotor is provided. This system includes an impeller unit in which an impeller constituted by a first rotor and a second rotor is configured in multi stages, in which the first rotor and the second rotor are driven in reverse rotational states to each other by driving motors of the respective rotors and respective target materials to be mixed sequentially pass between the multi-stage impeller units at once by a one-pass method, and as a result, a total working time for processing of dispersion-emulsion is significantly shortened, uniformity of a particle size is enhanced by micro shearing (cutting) of the respective mixed materials.
