The invention concerns a semi-continuous method for preparing an emulsion of droplets of a phase A in a phase B, including the following steps: (i) mixing an amount of phase A and an amount of phase B using a multishaft mixing system comprising at least one scraping agitator, so as to obtain a dispersion of phase A in phase B with a volume concentration of phase A higher than 74 %; (ii) diluting the dispersion obtained in step (i) by adding an additinal amount of phase B, and mixing using said multishaft mixing system, so as to obtain an emulsion of droplets of a phase A in a phase B.

L'invention concerne un procédé semi continu de préparation d'une émulsion de gouttelettes d'une phase A dans une phase B, comprenant les étapes suivantes : (i) mélange d'une quantité de phase A et d'une quantité de phase B au moyen d'un système de mélange à arbres multiples comprenant au moins un agitateur raclant, de manière à obtenir une dispersion de la phase A dans la phase B avec une concentration volumique de la phase A supérieure à 74 % ; (ii) dilution de la dispersion obtenue à l'étape (i) par ajout d'une quantité supplémentaire de phase B, et mélange au moyen dudit système de mélange à arbres multiples, de manière à obtenir une émulsion de gouttelettes d'une phase A dans une phase B.
