The present invention relates to a device intended to produce a heated emulsion of a liquid, in particular milk, with air. The device comprises a body ( 10 ) in which there are obtained steam inlet, a drink inlet ( 12 ), an air inlet ( 13 ) and a mixing chamber ( 14 ) communicating with said inlets and with an emulsion delivery hole ( 15 ). Between the mixing chamber ( 14 ) and the delivery hole ( 15 ) there are provided valve means ( 17, 17 ') capable of rotating between an open position, adapted for placing the mixing chamber ( 14 ) in fluid communication with the delivery hole ( 15 ), and a closed position of said mixing chamber, in which the steam jet is forced to exit from the body ( 10 ) passing through the air and drink inlets ( 12, 13 ), to sterilise the device.
