Abstract

A nanoparticle production method, production apparatus and automatic production apparatus that allow continuous mass production of nanoparticles with a uniform particle diameter and allow freely adjusting the generation time are provided. This nanoparticle production apparatus is characterized by being configured from: reaction tubes (30, 40) which are filled with the same solvent (11) as that in a ingredient liquid (18), which is used in nanoparticle production and comprises an ingredient material (12) mixed into the solvent (11); a heating apparatus (22) which controls the temperature of the solvent (11) in the reaction tubes (30, 40) to the synthesis temperature of the nanoparticles (26); inflow ends (30e, 40e) of the reaction tubes into which the ingredient liquid (18) is supplied; rotors (35, 45) which form spiral flows (e, j) along the inner surface of the outer walls (30h, 40h) of the reaction tubes while mixing the ingredient liquid (18) supplied and the solvent (11) present in the reaction tubes (30, 40); and outflow ends (30f, 40f) of the reaction tubes (30, 40) for forming, in the spiral flows (e, j), nanoparticles (26) from the ingredient material (12) and discharging a generation liquid (65) containing the nanoparticles (26).
