1. A mixer for mixing a plurality of fluid materials one another, having fluid characteristics of being fed in a pipe by a pressure difference between an upstream side and a downstream side inside the pipe, comprising:

  • a nozzle having a fluid discharge outlet for discharging the fluid material, a fluid supply hole communicated with the fluid discharge outlet for supplying the fluid material to the fluid discharge outlet, a gas ejection hole formed around the fluid discharge outlet for forming a high-speed vortex flow of a gas in front of the fluid discharge outlet, and a gas supply hole communicated with the gas ejection hole for supplying the gas to the gas ejection hole;

    a fluid supply means for supplying each of the plurality of fluid materials to the fluid supply hole of the nozzle, the fluid supply means comprising a flow rate regulating means configured to be capable of regulating relative supply flow rates of the plurality of fluid materials;

    a gas supply means for supplying the gas to the gas supply hole of the nozzle;

    a mixed material characteristic detecting means for detecting characteristics of a mixed material which has been discharged in a coexistent state from the fluid discharge outlet of the nozzle, and crushed into fine particles by the high-speed vortex flow of the gas to be ejected in a uniformly mixed state; and

    a control means for controlling the flow rate regulating means according to a detection result by the mixed material characteristic detecting means.
