The present invention provides a device 1 for producing milk foam, which makes use of Couette flow and a high shear stress that is accordingly applied to a milk-air mixture in a gap between a housing, in particular an outer cylinder, and a rotating element rotating arranged therein. The device further comprises a milk supply circuit supplying the fluid inlet with milk and an air supply circuit supplying the fluid inlet with air, both supply circuits being independent from each other.

The invention refers to a fluid foaming machine (100) for producing foam comprising a fluid container (30) where the fluid is arranged, and a foaming device (40) through which fluid flows and is heated and/or foamed, the machine (100) further comprising at least a cooling unit configured to maintain permanently refrigerated both the fluid container (30) and the foaming device (40) during fluid preparation and during stand-by of the machine (100).

A device for frothing a liquid includes a tube-shaped housing with an inner surface having a curved periphery. At least one inlet is arranged in a lateral area of the housing for letting in the liquid and a frothing gas, and may have a tangential orientation with respect to the curved periphery of the inner surface of the housing. End faces of the housing are open and function as outlets of the device, where a longitudinal axis of the housing may extend in a horizontal direction. Rings may be provided inside the housing for keeping a rotating flow inside the housing during a period of time which is sufficiently long for a frothing process to take place in an effective manner.

An automated frothing assembly. The automated frothing assembly has a wand module that includes an elongate member having an inlet, one or more outlets, and a fluid passageway extending between and in fluid communication with the inlet and the plurality of outlets. At least one of the one or more outlets extends parallel to a vertical plane that includes the centerline of the elongate member and at an acute angle relative to a horizontal plane that is perpendicular to both the vertical plane and the centerline of the elongate member. The assembly further includes an actuator configured to be operatively coupled to the wand module and to drive the movement of at least a portion of the wand module along an axis, and an electronic controller configured to be electrically coupled to the actuator and to control the operation of the actuator to control the movement of the wand module.

A machine (1) for homogenising a food substance has: a container (10) with a side wall (11) and a bottom wall (12) delimiting a cavity (10); an impeller (30) with an impelling member (31) forming an impelling surface (31,31,31) that is drivable in rotation (r) about a central axial direction (30) of the impelling surface (31,31,31) for imparting a mechanical effect to the food substance; and a module (20) which has a housing means (22) that contains an inner chamber (22,22a) and that delimits a seat (21) for the container (10), the chamber (22,22a) containing an electric motor (24). The electric motor (24) has an output drive axis (24) with a driver device (24) configured to drive a follower device (35) of the impeller (30). The driver device (24) and the follower device (35) are magnetically coupled through a sidewall (11) and/or bottom wall (12) of the container (10). The driver device (24) comprises a ferromagnetic or magnetic field-generating element (24a) that is arranged to be magnetically coupled to a corresponding ferromagnetic or magnetic field-generating element (36) of the follower device (35). The follower device (35) extends over a predominant part of the bottom wall (12) of the container (10) or across a substantial part of the wall (12) along a diameter thereof. The driver device (24) extends over a predominant part of a bottom part of the seat (21) or across a substantial part of the bottom part of the seat (21) along a diameter thereof. The ferromagnetic and magnetic field generating elements (24a,36) are positioned at extremal or peripheral parts of the follower device (35) and of the driver device (24).

A whipped cream dispenser including a main body comprising a frame, a base, and a top portion, the top portion including a user interface with a touchscreen. The main body includes a pump for introducing a refrigerated ingredient, at least one surface passage tube containing the refrigerated ingredient, a mixing manifold for receiving an injection of one or more flavors, a NIM venturi for receiving the one or more flavors and for receiving an injection of gas to produce a gas-infused mixture, and a whipper tube comprising a whipper wand, the whipper wand configured to force the gas-infused mixture into the refrigerated product to produce a final whipped product.

For a milk delivery device (1) which delivers milk (7) on the basis of the Venturi effect with the aid of a steam flow (9) output from a steam nozzle (2), it is provided, by corresponding orientation of an admixing opening (4) and optionally with the aid of deflecting surfaces (46), to allow a milk flow (8) sucked up by the steam flow (9) to flow tangentially onto the steam flow (9) in order thereby to be able to still ensure that the milk flow (8) is delivered in a manner as free as possible from disturbances, even in the event of very low flow rates of the milk flow (8). For this purpose, even before the milk flow (8) enters into contact with the steam flow (9), the milk flow (8) is oriented in the direction (51) of the steam flow (9).

The invention relates to a device for preparing milk froth that can be optionally hot or cold, or for dispensing optionally hot or cold milk (1), said device comprising a milk container (4) that can be removed from the device, a milk inlet which connects the milk container (4) to a cold froth device via a milk valve section, said cold froth device being activatable by means of an air valve section, and comprising an outlet line (15) that is located downstream of the cold froth device and comprises an outlet (16). The milk container (4) can be inserted into the device (1) in a guided manner and the base (4a) of said container is equipped with a milk snap-in valve (17). A complementary receiving section (17a) for the milk snap-in valve is fixed in the device (1) and is formed as a milk inlet directly on the milk valve section. When the milk container (4) is inserted, the milk snap-in valve (17) engages in the complementary receiving section (17a) for the snap-in valve and is locked therein.

A liquid mixing device includes: a cup body provided with an accommodating cavity; a cup holder, the cup body being detachably supported on the cup holder; and a Venturi structure integrally formed with the cup holder and located on a side of the cup body, the Venturi structure including a mixing cavity, a liquid inlet channel connected to the mixing cavity, a steam channel for connecting a steam source and an outlet channel for outputting, the steam channel and the outlet channel being connected to the mixing cavity, the liquid inlet channel being connected to the accommodating cavity through a liquid conveying pipeline, and the liquid inlet channel being connected to the liquid conveying pipeline at an angle. The complete Venturi structure is integrated with the cup holder, so that the number of parts is reduced, thereby making mounting and disassembly more convenient, thus providing great convenience to users.
