A steam wand assembly for an espresso machine has features for preventing overheating of the tip of the steam wand. In a first aspect there is provided a steam wand device comprising a metallic main body tube, a steam hose that passes through the tube, the steam hose also passing through a flexible spacer that is within the tube. In a further aspect there is provided a steam wand device comprising a main body tube having a metallic primary tube and a metallic tip, the primary tube and the tip being attached to one another by a polymeric steam nozzle, the nozzle having a central bore that extends from an inlet adjacent to a lower end of a steam hose to an exit opening.

Operating unit for steam discharged from a steam lance in a controlled manner using a manually displaceable operating element. The operating element is displaced in one direction from an engaged starting position, in which there is no steam discharge, into engaged positions for discharge of determined amounts of steam, or displaced in the opposite direction, in which the amount of steam varies with the displacement. The operating element has a fixed casing, an outlet head displaceably mounted on the casing, a steam lance fastened to the head, and a displaceable casing including the operating element. The casing is engaged in the starting position or in the positions or can be displaced in the opposite direction, in which the steam is almost continuously variable. Milk froth is produced optimally according to the desired discharge type, in accordance with the amount of milk located in a cup.

A machine is provided for preparing a desired beverage product from infusible materials. The machine includes a brew chamber that is adapted to hold the infusible materials, the brew chamber having an inlet and an outlet. An inlet tube is provided for transferring a fluid from a fluid receptacle to the inlet of the brew chamber and a dispensing tube is provided for transferring fluid from the outlet of the brew chamber to the receptacle. A fluid pump is provided for recirculating fluid through the brew chamber. In another aspect, a machine is provided for preparing a desired beverage product containing a gas. The machine includes a fluid pump for recirculating fluid from a fluid receptacle through an inlet tube to a dispensing tube and back to said fluid receptacle. The machine further includes an air pump disposed between the inlet tube and the fluid pump for introducing air into said beverage fluid that is recirculated by said fluid pump. A pod for use with the machine is also provided.

A fan-based steaming and foaming device is provided with a fan assembly and an activation device between a steam tube and an ejection tube. The invention employs an air pressure difference of a fan to directly inject, into a liquid, air required for foaming.

A mixing apparatus has a first port for receiving milk, a second port for receiving steam and a mixing chamber for mixing milk, steam and air. A channel arrangement connects the ports as well as defining an air intake channel which leads to a frothing section. An adjustment element is provided for adjusting a seal in the vicinity of the air intake channel, thereby to adjust a frothing level.

A method of operating a milk frothing device that includes at least one processor operatively associated with one or more actuators. The method is performed by the at least one processor and includes calculating a number of the actuators activated by way of contact with an underside of a vessel, determining a presence or an orientation of the vessel based on the calculated number of the activated actuators, and controlling an operation mode of the milk frothing device based on the determined presence or orientation of the vessel.

A steam dispensing apparatus for hot beverage preparation may include: a boiler configured to generate steam and comprising a first outlet; a wand configured to introduce the steam into a container; a steam supply conduit connected to the first outlet of the boiler and configured to supply the steam to the wand; and a valve for dispensing the steam to the wand and for draining condensation water formed in the steam supply conduit upstream from the valve, during a closing time of the valve elapsed from a previous dispensing operation, wherein the valve is interposed between the wand and the steam supply conduit. The valve may include a hollow body that includes: a steam inlet connection; a steam outlet connection; a condensation water drain connection; a cartridge configured to perform angular movements about a longitudinal axis; and a control knob, connected to the cartridge to impart the angular movements thereto.

The system for foaming milk comprises a container (2) for milk; an air inlet (3); a pump (4), wherein liquid milk is mixed with the air in order to produce foamed milk; and an outlet (6), wherein foamed milk is supplied, wherein the container is a container for powdered milk, and wherein the system for foaming milk further comprises a tank (8) for water and a premixing chamber (9). In the method for foaming milk, the milk is provided as powdered milk and is premixed with water in order to provide liquid milk which is mixed with the air in order to produce foamed milk. It enables a system and method for foaming milk to be provided which achieves the foaming of the milk with a “gel” effect from dehydrated powdered milk, the durability of which is much greater than liquid milk.

In a system including a beverage preparation machine and a compatible steam wand (11), the machine has a wand holder (1) for releasably mounting the wand and a source of steam. The machine includes a steam nozzle (23) engageable with the wand and mounted for movement between an operative position in which it is fluidly connected with the source of steam and a rest position in which it is fluidly isolated from the source of steam. The nozzle is biased to the rest position. When the nozzle is in its rest position it can be at least partially engaged with the wand before the wand is fully inserted in the holder. The arrangement such that the steam nozzle (23) is moved to the operative position on insertion of the wand fully into the holder.

A milk-frothing apparatus for preparing high quality micro-foamed milk for coffee drinks consistently and at high volume. A machine having one or more steaming stations includes an elevator at each station with an elevator-mounted steaming wand have a precise angle at the discharge end. The elevator-mounted steaming wand is configured to travel from an upward stowed status to a downward deployed status to insert the discharge end of the elevator-mounted steaming wand into milk inside a pitcher precisely located on the machine. A steam boiler is hydraulically coupled to the elevator-mounted steam wand via flexible tubing and an infrared sensor monitors the temperature of the pitcher during a downward deployed status. An LCD screen with operator controls and displays oriented to coincide spatially with the elevator indicate different operational settings selected by the user and related to machine operation.
