ギの超音波で乳化させることができる。 In the apparatus of the present invention having the above configuration, when the ultrasonic horn 1 vibrates, a hydrodynamically unstable region is formed in the tip 5 of the ultrasonic horn that is inclined with respect to the liquid level and in the fluid near the tip 5. The surface is raised at the upper end of the tip 5 and pressed down at the lower end thereof, and is brought into close contact with the tip 5 between the raised portion and the pressed down portion. By forming this unstable region, the influence of the viscosity and compressibility of the liquid is alleviated, and since the tip 5 is not immersed in the liquid as described above, there is no influence of liquid pressure, and cavitation nuclei can easily form in the liquid. It can be formed and emulsified using low-energy ultrasound waves.
