  • Patent number: 7637205
    Abstract: The invention relates to dispensing devices for drinks or similar dosable liquid foodstuffs, e.g. coffee, milk or soft drinks, comprising manually actuatable selector switches for determining the type and quantity of the foodstuff to be dispensed. The aim of the invention is to simplify the use of one such dispensing device. To this end, said device is provided with an identification device for identifying different types of containers for receiving the foodstuff with subsequent consumption from the container, and for emitting an identification signal describing the container. The dispensing device is also provided with a valve device which, on the basis of the identification signal, connects at least one of a plurality of supply devices for supplying a defined foodstuff or a mixture of defined foodstuffs by means of a filling device, and fills the container with a predetermined quantity of the defined foodstuff or the mixture thereof.

  • Publication number: 20090293733
    Abstract: Various forms of apparatus (1) for preparing and dispensing beverages, preferably based on coffee, can receive instructions from a customer and deliver the beverage automatically. The apparatus is preferably capable of fully automatic cleaning in a cleaning cycle in which a cleaning agent is flushed through the lines (62, 64), and the apparatus is preferably arranged to ensure that not only are the lines cleaned properly but that no cleaning agent can be dispensed. The apparatus includes a brewer assembly (78) having a chamber (81) in which freshly ground coffee can be introduced and either espresso or filter coffee can be automatically prepared by passing hot water through the chamber and removing the spent coffee grounds. The coffee may be stored as coffee beans in sealed containers (208) that can automatically be pierced to release the beans which are ground immediately before preparation of the beverage.

  • Patent number: 7252034
    Abstract: A dispensing unit for dispensing hot, dairy-based beverages has a self-contained refrigerated unit located above a venturi-type emulsification foaming head. The dispensing unit has particular applicability to the dispensation of foamy, hot milk for use in beverages such as cappuccino and nonfoamy, hot milk for use in beverages such as coffee latte, hot chocolate, and other hot dairy-based beverages. The refrigeration unit accommodates a “bag in box” cold milk storage container of the type widely used in food service establishments. The dispensing unit employs a pinch valve that avoids direct contact between the milk and the valve components. The refrigerated milk is stored above the level of the foamer head so that the flow of milk results partially from gravitational force on the milk, and is not totally dependent upon venturi suction created in the foamer head. Also, selective actuation of beverage choice switches generates commands to produce different beverages at different temperatures.

  • Patent number: 6840158
    Abstract: Device for preparing a coffee drink having a visually appealing crema layer comprises a container for receiving flavor-containing materials and allowing it to interact with pressurized hot water to produce a coffee drink, an orifice for converting the coffee drink into a high speed drink jet, and a cyclone channel located below the orifice and adapted to interact with the jet to generate a cyclone zone therein during preparing the coffee drink. The cyclone zone stays alive by constantly drawing air in from atmosphere to emulsify with the coffee drink within the cyclone zone and constantly driving the resulting emulsion out of the cyclone zone as a result of the momentum of the jet. The emulsion separates into a coffee drink layer and a crema layer on top of the coffee drink upon being received in a cup.
