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) (US7375140)
A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner is provided wherein 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 the 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. A process for producing an emulsion, comprising: feeding a flow of a dispersion phase from a dispersion phase-feeding channel to a flow of a first continuous phase flowing in a microchannel at a first junction to form a two-layered flow consisting of the flow of the first continuous phase and the flow of the dispersion phase;
and
feeding the two-layered flow consisting of the flow of the first continuous phase and the flow of the dispersion phase to a flow of a second continuous phase flowing in a microchannel at a second junction, thereby forming an emulsion consisting of the dispersion phase in a flow comprising a liquid micro-particulate separated from the first continuous phase and the second continuous phase.
[claim2]
2. A process for producing microcapsules, comprising: feeding a flow of a dispersion phase from a dispersion phase-feeding channel to a flow of a first continuous phase flowing in a microchannel at a first junction to form emulsions comprising liquid micro-particulates of the dispersion phase;
and
feeding the flow of the first continuous phase containing the emulsions to a flow of a second continuous phase flowing in a microchannel at a second junction, thereby forming microcapsules in the flow of the second continuous phase, the microcapsules containing the emulsions encapsulated in the first continuous phase as shells.
