PURPOSE:To rapidly homogenize dispersoid in a medium by mounting an inert gas introducing pipe and a jet dispersing accelerating apparatus to a mixing tank. CONSTITUTION:A paint raw solution is supplied into a pressure-resistant container 1 from a supply pipe 3. Subsequently, nitrogen gas is supplied into the pressure-resistant container 1 from an inert compressed gas cylinder 4 through an inert compressed gas introducing pipe 5 and injected in the paint raw solution of the pressure-resistant container 1 from a blow-in nozzle 6. The injected nitrogen gas is dissolved in the paint raw solution to be dispersed as gas bubbles. A part of the undissolved nitrogen gas is discharged to the outside from a gas venting exhaust pipe 9. The pressure of the nitrogen gas is adjusted by a pressure reducing valve 7 and, the higher this pressure, the more the dispersing effect of the paint raw solution is enhanced. By this method, a dissolving speed is increased.
