Abstract
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 multi-shaft 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 additional amount of phase B, and mixing using said multi-shaft mixing system, so as to obtain an emulsion of droplets of a phase A in a phase B.
