Automatic apparatus for treating milk by means of steam comprises a steam-generating source, a reservoir containing the milk to be treated, a mixing chamber 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 opening into the mixing chamber, the chamber being provided with an opening for the delivery of the mixture produced, as well as a peristaltic pump operating on the milk duct between the reservoir and the chamber and driven by an electric motor 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, a respective duct connecting the air source to the mixing chamber in order to bring a predetermined air-flow thereto, and a milk frothing chamber disposed downstream of the mixing chamber 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.

We claim: 1. An automatic apparatus for treating milk by means of steam, the apparatus comprising: a steam-generating source, a reservoir containing the milk to be treated, a mixing chamber, a milk duct connecting said milk reservoir to said mixing chamber, a peristaltic pump operating on said milk duct for bringing a milk flow at a predetermined flow-rate to said mixing chamber, an electric motor, with adjustable speed, being connected to said peristaltic pump to drive the same, a steam duct connecting said steam-generating source to said mixing chamber, a first solenoid valve on said steam duct, said steam-generating source providing a steam flow at a predetermined flow-rate to said mixing chamber through said steam duct, a delivery opening provided in said mixing chamber, a central control unit with at least one microprocessor having functions, obtainable by means of dedicated buttons, at least for adjusting a rate of rotation of said electric motor and hence for adjusting the flow-rate of the peristaltic pump according to the temperature to be adopted by the flow of milk in the mixing chamber as a result of the admission of the predetermined flow of steam through said first solenoid valve. 2. An automatic apparatus for treating milk by means of steam, the apparatus comprising: a steam-generating source, a reservoir containing the milk to be treated, a mixing chamber, a milk duct connecting said milk reservoir to said mixing chamber, a peristaltic pump operating on said milk duct for bringing a milk flow at a predetermined flow-rate to said mixing chamber, an electric motor, with adjustable speed, being connected to said peristaltic pump to drive the same, a steam duct connecting said steam-generating source to said mixing chamber, a first solenoid valve on said steam duct, said steam-generating source providing a steam flow at a predetermined flow-rate to said mixing chamber through said steam duct, a delivery opening provided in said mixing chamber, an air source, an air duct connecting said air source to said mixing chamber, a second solenoid valve on said air duct, a milk frothing chamber located downstream of said mixing chamber and connected thereto by said delivery opening of the mixing chamber, a product delivery opening in said frothing chamber, a central control unit with at least one microprocessor having functions, obtainable by means of dedicated buttons, at least for adjusting a rate of rotation of said electric motor and hence for adjusting a flow-rate of the peristaltic pump according to the temperature to be adopted by the flow of milk in the mixing chamber as a result of the admission of the predetermined flow of steam through said first solenoid valve. 3. An automatic apparatus for treating milk according to claim 2, wherein said air source provides an air flow at a predetermined flow-rate to said mixing chamber through said air duct and said second solenoid valve, resulting in heating and frothing of the milk. 4. An automatic apparatus for treating milk according to claim 1 wherein the treatment is constituted by heating the milk to a predetermined temperature. 5. An automatic apparatus for treating milk according to claim 1, wherein the microprocessor for controlling the electric motor of the peristaltic pump disposed in the duct for the supply of the milk to the mixing chamber, further comprises the function of reversal of the direction of rotation of the motor. 6. An automatic apparatus for treating milk according to claim 2, wherein the air flow for the frothing of the milk reaches the mixing chamber by suction brought about by the flow of steam through a device by the Venturi effect, said device being located on the steam duct. 7. An automatic apparatus for treating milk according to claim 2, wherein the air flow for frothing the milk reaches the mixing chamber in the form of a continuous pressurized flow. 8. An automatic apparatus for treating milk according to claim 2, wherein the air flow for frothing the milk reaches the mixing chamber in the form of pulses of regulated duration.
