発明の名称 (英語) Method and device for producing micro-droplets 実績あり
発明の概要(英語) A method and an apparatus for producing various types of microdroplets.
The apparatus has a cross intersection portion at which a first continuous phase, a first dispersion phase, and a second dispersion phase intersect with each other.
A first liquid feed device controls the first dispersion phase and a second liquid feed device controls the second dispersion phase.
A control device is connected to the first liquid feed device and the second liquid feed device.
The first liquid feed device and the second liquid feed device are controlled by a signal from the control device so that microdroplets formed of the first dispersion phase and microdroplets formed of the second dispersion phase are sequentially produced.
特許請求の範囲(英語) [claim1]
1. An apparatus for producing microdroplets, comprising: a microdroplet producing portion including: a cross intersection portion at which a first continuous phase supplied from a continuous phase supply channel, a first dispersion phase supplied from a first dispersion phase supply channel, and a second dispersion phase supplied from a second dispersion phase supply channel intersect with each other;
a first liquid feed device controlling the first dispersion phase;
a second liquid feed device controlling the second dispersion phase; and
a control device connected to the first liquid feed device and the second liquid feed device, wherein the first liquid feed device and the second liquid feed device are controlled by a signal from the control device so that first primary microdroplets and first fine satellite droplets formed of the first dispersion phase and second primary microdroplets and second fine satellite droplets formed of the second dispersion phase are sequentially produced;
a microdroplet supply channel supplying the first primary microdroplets and the second primary microdroplets and the first fine satellite droplets and the second fine satellite droplets from the microdroplet producing portion;
an expansion portion connected to the microdroplet supply channel; and
a branching portion having a primary droplet recovery channel connected to a front end of the expansion portion to recover the first primary microdroplets and the second primary microdroplets, a first fine satellite droplet recovery channel positioned on one side of the primary droplet recovery channel to recover the first fine satellite droplets, and a second fine satellite droplet recovery channel positioned on the other side of the primary droplet recovery channel to recover the second fine satellite droplets.
[claim2]
2. The apparatus for producing microdroplets, according to claim 1, wherein by the signal from the control device, microdroplets having uniform sizes and different components are alternately produced at a regular period.
[claim3]
3. The apparatus for producing microdroplets, according to claim 2, wherein by the signal from the control device, the period is changeable.
