  • Fine channel device, fine particle producing method and solvent extraction method
    Patent number: 7718099
    Abstract: A fine channel device capable of producing fine particles in an industrial scale, hardening the fine particles immediately after the production and recovering the fine particles from a medium without collapsing the shape of the produced fine particles, a fine particle producing method using the fine channel device and a solvent extraction method using the fine channel, are presented. The fine channel device comprises a fine channel provided with an inlet port and an inlet channel which feed a dispersion phase, an inlet port and an inlet channel which feed a continuous phase, and an outlet channel and an outlet port which discharge fine particles produced by the dispersion phase and the continuous phase, wherein the inlet channel for feeding the dispersion phase and the inlet channel for feeding the continuous phase are joined at an arbitrary angle, and the two inlet channels are connected to the outlet channel at the arbitrary angle.
