A beverage supply apparatus 100 includes milk tank 3, milk flow path L3, pump 7 for delivering a beverage, air flow path L6, pump 9 for supplying air configured to be capable of changing the discharge flow rate, release path L7 for discharging air flowing through air flow path L6 to the outside, on-off valve V7, first throttle part 16, and second throttle part 17. One end of release path L7 is connected to release point Z8 in air flow path L6, and the other end is open to the outside. On-off valve V7 is disposed in a flow path extending between release point Z8 and pump 9 in air flow path L6, and opens and closes this flow path. Throttle part 16 is disposed in a flow path extending downstream of release point Z8 in air flow path L6, and throttle part 17 is disposed in release path L7.

A beverage dispenser for dispensing either a hot or cold beverage, for example tea, from a common mixing chamber and a method for making and/or operating the same is disclosed. The dispense has a source of hot water, usually a heater, and a source of water, a refrigeration system to cool the water and one or more sources of flavor. The hot or cold water, or both can be provided to the common or same, mixing chamber and mixed assisted with a static and/or dynamic mixer and then dispensed. The last portion of the water is used to rinse for the next beverage. Flavor or syrup pump current is sensed to provide the appropriate amount of flavor concentrate to a known quantity of water to form a beverage of appropriate strength or syrup.

System for preparing beverage consumptions comprising a beverage preparation device, and at least one exchangeable supply pack. The beverage preparation device comprises a mixing chamber having a beverage outlet, liquid supply means including a liquid flow path for supplying a liquid to the mixing chamber; air supply means for supplying air to the liquid flow path, and a drive shaft. The at least one exchangeable supply pack includes a container for holding a beverage related ingredient, and a doser arranged for supplying the beverage related ingredient in a dosed manner. The exchangeable pack and the device are mechanically connectable. When connected the doser is in fluid communication with the mixing chamber and the drive shaft is arranged for transmitting torque to the doser, such that when activated, beverage related ingredient is supplied from the outlet of the doser into the mixing chamber.

A coffee machine includes: a filter holder suitable for containing at least one coffee dose; a dispensing unit with dispensing nozzles suitable for sending a flow of hot water on the coffee dose; a water system provided with a pump to supply pressurized water towards the dispensing nozzles; a heater to heat the water to be supplied to the dispensing nozzles; a dispensing valve to enable/disable the supply of hot water towards the dispensing nozzles; a pre-infusion valve installed upstream the dispensing valve; and a control unit comprising actuation means to actuate the pre-infusion valve. The pre-infusion valve is a two-way electrovalve of programmable proportional type.

An apparatus for brewing and dispensing beverages such as coffee, said apparatus comprising a water tank comprising a water inlet configured for fresh water supply, and one or more heater elements, said apparatus comprising a water tank outlet, which is connected via a hot water channel to a water faucet a brewing chamber and a dispensing nozzle, wherein said hot water channel has at least one section forming a flow path for hot water, said at least one section of said hot water channel is configured such that it is in direct thermal contact with the periphery of said water tank along the entire length of said at least one section of said hot water channel, and such that said at least one section of said hot water channel extends substantially parallel to the periphery of said water tank.

Described herein is an espresso coffee machine having a water feeding hydraulic circuit, at least one boiler for heating water, located downstream of the water feeding hydraulic circuit, a coffee dispenser unit, located downstream of the boiler and provided with at least one coffee panel configured for mixing hot water with coffee, and a first pumping hydraulic circuit, provided with at least one pump for the water and interposed between the water feeding hydraulic circuit and the boiler. Between the water feeding hydraulic circuit and the boiler is interposed a second pumping hydraulic circuit, connected in parallel with the first pumping hydraulic circuit and provided with a lever pumping unit. The lever pumping unit works at room temperature, being physically separated both from the boiler, and from the coffee dispenser unit.

Aspects relating to a method and apparatus for venting a heater tank of a beverage forming apparatus using a vent valve that is opened and closed based on an operation to move a brew chamber lid between an open lid position and a closed lid position are provided. In one aspect, the vent valve may be positioned on a vent line distinct from a delivery line that delivers heated liquid from the heater tank to the brew chamber. In another aspect, at least a portion of the delivery line may extend downwardly from the top of the heater tank to a location between the top and the bottom of the heater tank. In another aspect, the at least a portion of the vent valve may be attached to the handle for movement with the handle.

With a method for heating in particular milk or milk foam, in which the milk or the milk/air mixture is conveyed through a passage opening and hot steam is conveyed through at least one steam line transversely into this passage opening. The passage opening and the at least one inlet opening opening transversely into the steam line, the steam pressure in this and the pressure and the pressure in the passage opening with flowing milk or milk/air mixture are so coordinated that the hot steam at the at least one transverse inlet opening condenses in the passage opening directly on contact with the milk or the milk/air mixture. Consequently the additional energy produced by the phase change from steam to condensate water is transmitted directly as heat to the heat in the milk or the milk/air mixture.
