発明の名称 (英語) Process and apparatus for producing emulsion and microcapsules 実績あり
発明の概要(英語) (US7717615)
In a process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner, a dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by a shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.
特許請求の範囲(英語) [claim1]
1. An apparatus for producing an emulsion, comprising: (a) a microchannel formed on a substrate such that a dispersion phase thereof communicates with a continuous phase thereof;
(b) a plurality of first parallel electrodes formed in the microchannel on the substrate and in a direction perpendicular to the microchannel and arranged in stripes, a moving electric field applied to the parallel electrodes; and
(c) a plurality of second parallel electrodes formed on the substrate in a direction of the microchannel and arranged in stripes, wherein a moving electric field is applied to the second parallel electrodes by static electricity on the side of the continuous phase of the downstream of the microchannel.
[claim2]
2. The apparatus for producing an emulsion according to claim 1, wherein the moving speed of the moving electric field applied to the first parallel electrodes is varied, whereby a rate of forming the emulsion is varied.
