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.
A fine channel device comprising 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, characterized in that the inlet channel for feeding the dispersion phase and the inlet channel for feeding the continuous phase are joined at an arbitrary angle, and said two inlet channels are connected to the outlet channel at the arbitrary angle.
A fine channel device comprising an inlet port for feeding fluid, an outlet port for discharging the fluid, a common channel formed in a substrate to communicate the inlet port with the outlet port, and at least one fine channel communicated with the common channel at positions different from the inlet port and the outlet port, characterized in that the cross-sectional area of the common channel is increased gradually from the portion where the inlet port is communicated with the common channel to the portion where the outlet port is communicated with the common channel, or unchanged.
A fine particle producing method for producing fine particles by using a fine channel device 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, characterized in that the dispersion phase is transformed into fine particles by being joined with the continuous phase.
A fine particle producing method for producing fine particles by using a fine channel device provided with an inlet port and an inlet channel which feed a dispersion phase as a medium containing a gel-producing material, an inlet port and an inlet channel which feed a continuous phase as a medium containing a gel-producing dispersant, and an outlet channel and an outlet port which discharge fine particles produced by the dispersion phase and the continuous phase, characterized in that the dispersion phase is transformed into fine particles by being joined with the continuous phase, the particle size of the fine particles is controlled by changing the angle of the confluent portion at which the inlet channel for feeding the dispersion phase is joined with the inlet channel for feeding the continuous phase, and the fine particles are hardened in the fine channel and/or out the fine channel by the irradiation of light and/or heating.
