Abstract:
1. A Semi-continuous method for preparing an emulsion of droplets of a phase A in a phase B, comprising the following steps: (i) mixing a quantity of phase A and a quantity of phase B by means of a mixing system with multiple shafts comprising at least one scraper impeller, so as to obtain a dispersion of phase A in phase B at a volume concentration of phase A of more than 74%; and wherein said phase A is added to phase B at a mass flow rate of between 0.01 time and 3 times the mass of phase B per second, (ii) diluting the dispersion obtained at step (i) by adding an additional quantity of phase B, and mixing by means of said mixing system with multiple shafts, so as to obtain an emulsion of droplets of a phase A in a phase B.
