  • 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.

  • Patent number: 6723555
    Abstract: A fermentation apparatus is constructed to produce a known and repeatable amount of untainted fermentation product using multiple fermentation vessels. To facilitate further processing compatible with other product processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame. The container frame is configured to hold the sample vessels during fermentation and to transport the vessel array to or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula array is configured such that each cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because the fermentation volume for each individual sample vessel is smaller than a bulk fermentation apparatus, the fermentation product yields are predictable and cell growth rates can be effectively optimized.

    Abstract: An apparatus for producing and dispensing whipped soft drinks, hot chocolate and beverages which does not use mechanical whipping such as rotating blades, but rather accomplishes the whipping of the mixture of syrup and water used to produce the beverage by intermixing within a vented mixing chamber intersecting streams of syrup and water that are directed toward the intersection point under pressure. The apparatus embodies solenoid valves to control the flow of syrup and water into the mixing chamber of the apparatus.

  • Patent number: 6293187
    Abstract: The present invention relates to a milk frothing device with a steam pipe that extends through a base member and has at its end a nozzle, and with a container that can be placed underneath the nozzle. The base member along with the steam pipe and the nozzle is vertically displaceable within a longitudinal guide of a housing of the device. This permits immersing the nozzle into the container and frothing the milk disposed therein without needing the hand of a user to hold the container. This arrangement prevents scalds and improves ease of handling.

  • Patent number: 6289796
    Abstract: A single unit milk dispenser for producing hot frothed milk or hot non-frothed milk uses milk and steam. A reservoir supplies milk via an adjustable valve to a first chamber. For supplying frothed milk, steam is issued from a first steam outlet nozzle and mixes and froths with the milk in the first chamber and in an expansion chamber before being dispensed out of a collection chamber. For non-frothed milk, steam supplied from a second steam outlet nozzle is released to mix and swirl around with cold milk fed from the reservoir into the collection chamber. The rate of flow of milk out of the reservoir is normally adjusted for the two mode of operation, which mode is simply otherwise determined by which nozzle supplies steam, by turning a steam supply selection knob.

  • Patent number: 6253667
    Abstract: An emulsifying assembly comprising a milk supply duct and a mixing device for mixing at least steam and milk for preparing hot milk for cappuccino and similar beverages. The mixing device comprises at least one steam inlet, at least one milk inlet and an outlet while a first end of the milk supply duct is connected to the at least one milk inlet, a second open end of the at least one milk supply duct is situated at a height lower than the highest point of the at least one milk supply duct, while further, in use, the second open end of the milk supply duct is in fluid communication with a milk-filled milk container. The emulsifying assembly further comprises an aeration valve which is connected to the at least one milk supply duct, and with which the at least one milk supply duct can be aerated when the aeration valve is in its opened position. The milk container is placed in a cooling unit. The milk supply duct extends substantially inside the cooling unit.

  • Publication number: 20010003951
    Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter.

  • Patent number: 6192785
    Abstract: An automatic dispenser of frothed milk and pre-made liquid coffee received from refrigerated milk and pre-made liquid coffee containers that selectively delivers cold and hot Italian-style coffees, such as, cappuccino, latte, espresso, and other. The refrigeration mechanism is based in Peltier effect and has a chamber to store the milk and pre-made liquid containers which are accessible to a user. The heating mechanism includes a hot water tank and cone-shaped heat exchanger assemblies to heat the frothed milk and pre-made liquid coffee, respectively. The milk and pre-made liquid coffee are drawn by two separate pumps through fluid conduits from the refrigerated containers to the air valves to be frothed. If a user selects hot beverage, the flow is directed to the heat exchanger and then discharged through a nozzle to a cap. If a user selects cold beverage, the flow is directed to the nozzle to be discharged to the consumer.
