Patent ID: 7069843

Claim:
Heating and emulsifying device, in particular for heating and optionally emulsifying air and milk in a milk-based product, comprising: an emulsification chamber having an opening for the delivery of the milk with a predetermined degree of emulsion, a steam-inlet duct which opens into the emulsification chamber, a milk-inlet duct and an air-inlet duct which communicate with the steam-inlet duct, the air and the milk being drawn in by the partial vacuum created by the flow of steam, characterized in that it comprises an air-flow regulator and a milk-flow regulator, operatively associated with the air-inlet duct and with the milk-inlet duct, respectively, the air-flow and milk-flow regulators being structurally connected in a single body and being suitable for jointly varying the respective flow-rates so as to vary the emulsion/milk ratio progressively in the final product without affecting its temperature.
