Mixing apparatus, dispersion manufacturing apparatus and dispersion manufacturing method

A dispersion manufacturing apparatus comprising a plurality of nozzle groups each formed of nozzles for ejecting the same fluid arranged in group, the nozzles being provided with openings for ejecting fluid, to cause the plurality of nozzle groups to separately eject a plurality of fluids to react the fluids in areas on the extending lines of the nozzles to produce reaction products to disperse the reaction products in a dispersion medium, wherein

• the openings of the nozzles forming the nozzle groups are arranged along annular loci and the plurality of nozzle groups are arranged coaxially to each other,
• a plurality of supplying channels for supplying the plurality of fluids to the nozzle groups corresponding to the plurality of nozzle groups are annular in cross section in the direction perpendicular to the direction in which fluid supplied to the supplying channels flows and arranged coaxially to each other.

A method of manufacturing dispersion including reacting at least two different kinds of fluids to produce reaction products and dispersing particles formed of the reaction products in dispersion medium, the method comprising:

• preparing a mixing apparatus comprising a plurality of nozzle groups each formed of nozzles for ejecting the same fluid arranged in group, the nozzles being provided with openings for ejecting fluid, to cause the plurality of nozzle groups to separately eject a plurality of fluids to mix the fluids in areas on the extending lines of the nozzles, wherein the openings of the nozzles forming the nozzle groups are arranged along annular loci and the plurality of nozzle groups are arranged coaxially to each other, a plurality of supplying channels for supplying the plurality of fluids to the nozzle groups corresponding to the plurality of nozzle groups are annular in cross section in the direction perpendicular to the direction in which fluid supplied to the supplying channels flows and arranged coaxially to each other;
• and
• ejecting at least two different kinds of fluids supplied from the plurality of supplying channels from the nozzle groups.
