The invention addresses the problem of providing a novel method for controlling the particle size of deposited fine particles in a fine particle production method that introduces a fluid to be processed between at least two processing surfaces, which are disposed facing each other, are advancible and retractable, and at least one rotates relative to the other, to deposit fine particles in the thin fluid film which forms between said processing surfaces. A fluid to be processed is introduced between processing surfaces ( 1, 2 ) that are disposed facing each other, are advancible and retractable, and at least one rotates relative to the other to deposit fine particles in the thin fluid film that forms between the processing surfaces ( 1, 2 ). The particle size of said fine particles is controlled by controlling the temperature of the fluid to be processed that contains the deposited fine particles. Said temperature control can be accomplished by providing a temperature adjusting apparatus ( 33 ) and a jacket ( 34 ) in the flow channel or receptacle for the fluid to be processed after outflow and controlling the temperature of the fluid to be processed that contains the deposited fine particles. |
