Automatic apparatus for treating milk by means of steam comprises a steam-generating source (3), a reservoir (7) containing the milk to be treated, a mixing chamber (12) into which a flow of milk with a predetermined flow-rate and at least one flow of steam with a predetermined flow-rate are brought through respective ducts (6, 2) opening into the mixing chamber (12), the chamber (12) being provided with an opening (13) for the delivery of the mixture produced, as well as a peristaltic pump (17) operating on the milk duct (6) between the reservoir (7) and the chamber (12) and driven by an electric motor (18) with adjustable speed. The flow-rate of the pump and consequently the ratio between the flow of milk and the flow of steam can thus be varied so as to achieve the desired temperature in the final product. The apparatus includes an air source (5), a respective duct (4) connecting the air source (5) to the mixing chamber (12) in order to bring a predetermined air-flow thereto, and a milk frothing chamber (14) disposed downstream of the mixing chamber (12) and in communication therewith, and having an opening for the delivery of the product which, in the case in question, is heated and frothed milk. |
