Title (EN) PROCESS FOR PRODUCING EMULSION AND MICROCAPSULES AND APPARATUS THEREFOR
(FR) PROCEDE DE PREPARATION D'EMULSION ET DE MICROCAPSULES ET APPAREIL A CET EFFET
Abstract:
(EN) A process for producing an emulsion and microcapsules whereby an emulsion and microcapsules can be conveniently and quickly produced. Toward a continuous phase (5) flowing through a microchannel (2), a dispersion phase (6) is supplied from a dispersion phase-supplying port (4) as intersecting the flow of the continuous phase (5). Thus, a microdroplet (7) having a diameter smaller than the width of a channel for supplying the dispersion phase (6) can be formed due to the shear force of the continuous phase (5).
(FR) 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).
