The invention concerns a method and an implementing device, for making a mixture or and emulsion from at least an emulsifier and at least two fluids known to be immiscible, said fluids defining a dispersed phase and a continuous phase. The method is characterised in that the dispersed phase being either contained in an adapted tank, or continuously supplied, it comprises a first step which consists in pressurising the dispersed phase; then in suddenly depressurising said dispersed phase using means generating a coherent jet (5). Then an appropriate emulsifier is introduced into said coherent jet (5) with means for mixing the dispersed phase with said emulsifier thereby providing a resulting coherent jet (9) which is finally contacted with the continuous phase to obtain the mixture or the emulsion.
L'invention concerne un procédé, ainsi qu'un dispositif le mettant en oeuvre, pour la fabrication d'un mélange ou d'une émulsion à partir d'au moins un émulsifiant et au moins deux fluides réputés non miscibles, lesdits fluides définissant une phase dispersée et une phase dispersante; ce procédé est remarquable en ce que, la phase dispersée étant soit contenue dans un réservoir adapté, soit délivrée en continu, il comporte une première étape de mise sous pression de la phase dispersée puis, on effectue une dépressurisation brutale de ladite phase dispersée grâce à des moyens permettant de créer un jet cohérent (5). Un émulsifiant approprié est alors introduit dans ledit jet cohérent (5) grâce à des moyens assurant le mélange de la phase dispersée avec ledit émulsifiant et procurant ainsi un jet cohérent résultant (9) qui est finalement mis en contact avec la phase dispersante pour obtenir le mélange ou l'émulsion.
