1. A device for producing a dispersion comprising elements comprising at least one first phase, which are dispersed in a continuous phase substantially immiscible with the first phase, the device comprising:
at least one production nozzle comprising at least a first duct intended to convey a first fluid that forms the first phase, a second duct surrounding at least part of the first duct, the second duct being able to convey a second fluid that forms the continuous phase, and an outlet, the nozzle being able to form, at the outlet, a fluid jet comprising at least the first fluid and the second fluid surrounding the first fluid and
at least one fragmentation device for mechanically breaking up the fluid jet, positioned in the vicinity of the outlet of the nozzle, the fragmentation device comprising a mobile part relative to the nozzle, intended to break up the fluid jet mechanically into a plurality of elements comprising the first fluid dispersed in the continuous phase,
wherein the mobile part of the fragmentation device comprises a rotating or oscillating scraper, provided with successive openings, and the mobile part is mobile at least between a closed position, in which the outlet is not across from one of the openings and the mobile part is substantially in a flow axis of the fluid jet, and an open position, in which the outlet is across from one of the openings and the mobile part allows the flow of the fluid jet without splitting of the latter.
