An appliance for heating and/or frothing milk, in which steam or a mixture of steam and air acting as a heat carrier is injected into the milk, with the heating unit including an inner steam channel and an outer annular channel for the milk. The outer annular channel coaxially surrounds the inner steam channel, with hot steam or a mixture of steam and air being supplied at an upstream end of the steam channel and with milk being supplied at an upstream end of the annular channel. To improve the heat output and the energy efficiency of the heating unit and to reduce the maintenance requirement, the steam channel and the annular channel are separated from one another, with their downstream ends opening out into an outlet channel for discharging the heated and/or frothed milk.

A liquid dispenser is provided. The liquid dispenser includes a housing; a temperature control system; and a pump system. The pump system pumps multiple liquids. A method of dispensing a liquid into a beverage is also provided. A liquid dispenser includes a valve, a pump, and a nozzle. A liquid is selected from multiple liquids and a beverage shade is selected. The valve and the pump are activated to deliver the selected liquid to the nozzle in an amount that achieves the selected beverage shade.

A supply device for one or more beverage-dispensing machines (1a, 1b) is provided, having a holding space for the insertion of at least two storage containers (5a, 5b) for liquid foods, in particular milk, which storage containers can be connected to the one or more beverage-dispensing machines by food lines (4a, 4b, 4a′, 4b′). The supply device (2) has a cooling device (10) for the temperature control of liquid foods contained in the storage containers to a specifiable target temperature. A thermally conductive, in particular metal, contact surface (8a, 8b) is provided for each of the food containers (5a, 5b), which contact surface is in thermally conductive contact with a thermally conductive outer wall (7a, 7b), in particular bottom surface, of the storage container in question when the storage container is installed, in order to cool the contents of the storage container. In addition, the thermally conductive contact surfaces can be cooled by the cooling device (10) by separately controllable cooling circuits (9a, 9b).

A device for frothing milk and liquid food is disclosed having a frothing rotor and a motor adapted to rotate the frothing rotor, a seat adapted to substantially entirely contain the frothing rotor an inlet for feeding the milk or liquid food into the seat, an air inlet and an outlet of the milk or liquid food from the seat.

A device for processing milk foam for use in an automatic hot and/or cold beverage machine includes a milk pump to pump the milk foam, and a secondary processing device coupled to the milk foam pump to change the consistency of the milk foam. The secondary processing device includes a homogenizer to break up and distribute air bubbles in the milk foam. The homogenizer has a reducing region including a plurality of impact bodies arranged to define a channel labyrinth through which the milk foam is flowable. Additionally, there is provided a process for homogenizing milk foam utilizing the above device, includes steps of a) impacting divided partial flows of the milk foam with the impact surfaces to divide the air bubbles of the milk foam; and b) mixing the divided partial flows with the divided air bubbles together to form new partial flows.

A method automatically evaluates the quality of milk foam dispensed by a machine for dispensing milk-based beverages through the analysis of an image of the free surface of the frothed milk contained in a container, wherein the analysis uses automatic procedures for processing images for identifying and quantifying, in the processed image, a physical characteristic representative of the texture of the surface of the frothed milk and hence indicative of the quality of milk foam, the physical characteristic being the plurality of air bubbles.

An electronic system to remotely enable and locally control use of liquid milk in the preparation of beverages based on, or containing, liquid milk in beverage vending machines is disclosed.

A machine (1) for preparing beverages comprising a machine casing (2) and discharge (7) including a discharge casing (71) with an opening (72) confined by a side wall (73) and a base wall (74) that includes at least one discharge passageway (75) disposed on a side opposite to the opening (72). The discharge casing (71) comprises retention elements (76) arranged in substantially mutually opposite positions on the perimeter region of the casing opening (72), whereby the retention elements (76) provide a removable retention along a vertical longitudinal plane of said discharge casing (71) on the machine casing (2). Thus, the opening (72) is confined above by a downwards oriented portion of said machine casing (2) when retained thereon by said retention elements (76). The retention elements (76) are adapted to provide retention on the machine casing (2) and release therefrom by manual actuation thereof without requiring the use of tools.

New and novel structure(s) for cleaning surfaces have been disclosed. The device may include; a wiping surface, which may be disposable; a brush roll/larger debris gathering mechanism; a local debris storage and/or staging area, and a larger remote debris storage structure. Additionally, there are mechanisms and structures disclosed for powering the brush roll, activating the brush roll from an out of use position to an in use position, waste from one area to another. The invention at hand uniquely and inventively improves upon the known devices in this field.

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.
