The present invention provides a process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner. A dispersion phase (6) is ejected from a dispersion phase-feeding port (4) toward a continuous phase (5) flowing in a microchannel (2) in such a manner that flows of the dispersion phase (6) and the continuous phase (5) cross each other, thereby obtaining microdroplets (7), formed by the shear force of the continuous phase (5), having a size smaller than the width of the channel for feeding the dispersion phase (6).
La présente invention concerne un procédé de production d'une émulsion et de microcapsules qui permet de produire facilement et rapidement une émulsion et des microcapsules. Selon l'invention, une phase de dispersion (6) est alimentée depuis un orifice d'alimentation en phase de dispersion vers une phase continue (5) s'écoulant dans un microcanal (2) de façon que la phase de dispersion croise le flux de la phase continue (5). De cette manière, une microgoutellette (7) d'un diamètre inférieur à la largeur du canal d'alimentation de la phase de dispersion (6) est formée par la seule force de cisaillement de la phase continue (5).
