Device for preparing milk froth for cappuccino
First Claim
1. A device for heating and frothing a beverage, the device including an elongate frothing wand comprising:
- a generally tubular external sleeve;
an inner core within the external sleeve, wherein the inner core defines a steam conduit configured to pass steam from a supply end of the frothing wand to an expulsion end of the frothing wand;
a steam-discharge ring in fluid communication with the steam conduit and configured to eject steam into the beverage;
an annular airway defined by the external sleeve and the inner core, wherein the airway is configured to draw air from the supply end to the expulsion end of the frothing wand; and
an air-discharge ring in fluid communication with the airway and concentrically aligned with the steam-discharge ring, wherein the air-discharge ring is configured to direct air into the beverage upon ejection of steam from the steam-discharge ring, wherein the steam-discharge ring includes a plurality of steam-ejection orifices.
