A method and an apparatus for producing various types of microdroplets are provided. The apparatus has a cross intersection portionat which a first continuous phase, a first dispersion phase, and a second dispersion phaseintersect with each other; a first liquid feed devicecontrolling the first dispersion phase; a second liquid feed devicecontrolling the second dispersion phase; and a control deviceconnected to the first liquid feed deviceand the second liquid feed device, in which the first liquid feed deviceand the second liquid feed deviceare controlled by a signal from the control deviceso that microdropletsformed of the first dispersion phaseand microdropletsformed of the second dispersion phaseare sequentially produced.

Method and device for producing microdroplets

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.

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.

Method and device for producing micro-droplets

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.
