Embodiment Construction

[0036] Figures 1 to 3 Different embodiments of a milk frothing device 1 according to the invention are shown.

[0037] As shown in the figures, the frothing device 1 delimits a zone 2 for mixing milk 35 from a milk reservoir 3 with gas 49 . The device 1 comprises a supply 4 of pressurized gas 48 , 49 . This pressurized gas supply device 4 has a propellant gas duct 41 configured to deliver pressurized propellant gas 48 into the milk reservoir 3 for pressurizing the reservoir 3 and thus the pressurized milk 36 Propelled from reservoir 3 to mixing zone 2. The mixing area 2 may be located inside a milk duct 36' leading pressurized milk 36, for example a generally tubular element.

[0038] Milk 36 may be circulated under pressure at a flow rate of 100-1000ml / min, eg 200-600ml / min, such as 400-500ml / min.

[0039] The pressurized gas 48 is thus able to act like a gaseous piston on the body of the milk 35 in the reservoir 3 .

[0040] The gaseous actuation of the milk 35, 36, fo...

Abstract

A milk frothing device (1) delimiting an area (2) for mixing milk (35) from a milk reservoir (3) and gas (49), comprises a supply arrangement (4) of pressurized gas. The pressurized gas supply arrangement (4) has a propelling gas conduit (41) configured to deliver pressurized propelling gas (48) into the milk reservoir (3) to pressurize the reservoir and propel thereby pressurized milk (36) from the reservoir to the mixing area (2).

Description

technical field [0001] The field of the invention relates to a conditioning device for frothing milk, in particular a milk frother using pressurized gas to froth milk. Background technique [0002] Specialty beverages consisting at least in part of frothed or heated milk are becoming more and more popular. The most famous drink of this type is coffee of the cappuccino type. It consists of a liquid portion consisting of coffee covered with a layer of frothed milk which, due to its very low density, floats on top of the surface of the liquid. In general, preparation is time consuming, requiring handling operations and cleaning. [0003] The most common way to prepare a milk-based foam is to pour the desired amount of milk into a container, dip the coffee machine's steam output tube into the container, and stir the milk up and down to introduce the air needed to form the foam. [0004] There are also various devices that include heating and stirring means for heating the mil...
