Title
(EN) MEMBRANE EMULSIFICATION DEVICE WITH IMPELLER FOR MICROSPHERE CREATION
(FR) DISPOSITIF D'ÉMULSIFICATION MEMBRANAIRE AVEC IMPULSEUR POUR LA CRÉATION DE MICROSPHÈRES
Abstract
(EN)
The present disclosure is directed to cross-flow membrane emulsification devices 1 with an impeller 9. The devices disclosed herein can have a continuous phase housing 2 that houses an impeller, a dispersed phase housing 3, and a membrane 4 between the continuous phase housing and the dispersed phase housing. The impeller can be rotated about a rotational axis such that a continuous phase inside the continuous phase housing imparts a shear force on the membrane. A dispersed phase can be forced through the membrane such that the dispersed phase enters into the continuous phase in a direction that is perpendicular to the rotational axis of the impeller, thereby forming a dispersed phase microspheres.

La présente invention concerne un dispositif d'émulsification membranaire à écoulement transversal. Les dispositifs de l'invention peuvent avoir un boîtier de phase continue 2 qui loge un impulseur, un boîtier de phase dispersée 3, et une membrane 4 entre le boîtier de phase continue et le boîtier de phase dispersée. L'impulseur peut tourner autour d'un axe de rotation de telle sorte qu'une phase continue à l'intérieur du boîtier de phase continue exerce une force de cisaillement sur la membrane. Une phase dispersée peut être forcée à travers la membrane de telle sorte que la phase dispersée entre dans la phase continue dans une direction qui est perpendiculaire à l'axe de rotation de l'impulseur, formant ainsi des microsphères à phase dispersée.
