When fluid is mixed by a rotor and small vessel that has a narrow clearance between its wall and the rotor with the upper part covered by an endplate, the processing fluid becomes a high-speed thin-film spin flow. This flow possibly allows the peripheral speed to be over 30 m/s, which was unable to be obtained by a conventional high-speed mixer. As a result, the processing fluid obtains more and homogenous energy. In an actual experiment, we compared a high-speed thin-film spin mixer with a conventional high-speed mixer upon an emulsification experiment with soybean oil. The experiment proved that the former mixer could control the particle size distribution. It also proved that the same result could be obtained by continuous operation as by batch operation. In conclusion, the high-speed thin-film spin mixer can control particle size distribution with a high efficiency.
