(54) Emulsification apparatus and fine-grain manufacturing apparatus


(57) A fine-grain manufacturing apparatus 100 has a fluid device including a microscopic channel that has an orifice 203, 204, 205 which brings liquid to a jet 310, a channel wall having a piezoelectric element 206, 207 that actively oscillates liquid, and a unit that measures the diameter of grains floating in a fluid and the number of grains. The piezoelectric element 206, 207 oscillates to skid in the same direction as the flowing direction of a fluid. The fine-grain manufacturing apparatus 100 mass-produces grains having diameters thereof controlled.
