Abstract
A device for heating and emulsifying milk, especially to prepare a white coffee drink known as "cappuccino" with the assistance of a steam jet, which has a vacuum chamber surrounding a nozzle and formed with an emulsion discharge port, a passageway for admitting sucked-in air, and at least one passageway for the milk which enters the chamber on account of the negative pressure prevailing therein, thereby milk, air, and steam are mixed together in said chamber and then made to flow out through said discharge port.
Claims12
A device for heating and emulsifying milk, for preparing "cappuccino", comprising nozzle means for discharging steam, conduit means connected to said nozzle means to lead steam thereto, means defining a vacuum chamber encircling said nozzle means, said means defining a vacuum chamber being provided with an emulsion discharge port, first passageway means connected to said means defining a vacuum chamber for drawing in air by suction created by a vacuum in said means defining a vacuum chamber and second passageway means connected to said means defining a vacuum chamber for drawing in milk by suction created by the vacuum in said means defining a vacuum chamber, so as to mix and emulsify milk, air, and steam together within said means defining a vacuum chamber and to deliver the resulting emulsified mixture out through said emulsion discharge port by the force of the steam.
A device for heating and emulsifying milk for preparing cappuccino comprising a tube terminating at a first end in a nozzle and at a second end in a fitting provided with an annular seal, a cap for cooperating with said fitting to fix the second end of said tube in sealing engagement with a steam conduit, a sleeve defining a discharge port at a first end thereof and having a second end received over said tube and in frictional engagement with the annular seal of said fitting, said discharge port axially aligned with and lying spaced from said nozzle for said sleeve to define a vacuum chamber encircling said nozzle, means defining an air vent in said sleeve adjacent said second end, means defining a milk intake in said sleeve adjacent said first end axially spaced from said discharge port, and at least one lug extending from said sleeve beyond said first end thereof so that said device can be connected to a source of steam and be inserted into a container of milk to mix and emulsify the milk with air and steam.
