  • Publication number: 20160015074
    Abstract: A batch carbonation apparatus includes a housing defining a vessel cavity. The housing includes an agitation mechanism. The pressure vessel includes a cap that has a CO2 inlet and a CO2 outlet is provided. The pressure vessel also includes a seal. The pressure vessel is moveable into an out of the vessel cavity. A locking mechanism is provided and is attached to the agitation mechanism to removably lock the cap and seal relative to the pressure vessel. A CO2 source is connected to a plurality of valves where each valve has a differing pressure. A selection toggle is attached to the housing. A control mechanism is coupled to the plurality of valves. A user selects a desired carbonation level using the selection toggle and CO2 is introduced to the pressure vessel at a specified pressure wherein the agitation mechanism agitates liquid within the pressure vessel forming a carbonated beverage having a selected carbonation level. Also disclosed is a process of forming a carbonated beverage in a batch.

  • Patent number: 9107449
    Abstract: The present invention recognizes the need for an apparatus and method for creating carbonated beverages having a customizable carbonation level. The invention uses a CPU to control an inlet valve which connects a tank of pressurized carbon dioxide to a vessel containing the beverage to be carbonized. The tube connecting the tank of pressurized carbon dioxide to the vessel contains an orifice for reducing the carbon dioxide's flow rate, thereby increasing control over the amount of carbon dioxide introduced to the vessel. A motor agitates the vessel, causing the carbon dioxide to become absorbed in the beverage. During the pressurization process, the pressure inside the vessel is monitored by the CPU to determine whether more CO2 should be added to the vessel. An outlet valve causes excess pressure to drain from the vessel. An outlet orifice causes the pressure to release gradually, thus preventing the beverage from foaming.

  • Publication number: 20140305316
    Abstract: 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.

  • Patent number: 8225960
    Abstract: An ice dispense system for an ice dispenser is characterized by a chute having an ice receiving upper end in communication with an ice bin outlet passage and an ice dispensing lower end. Beginning with the chute filled with ice and its lower end closed, to dispense a selected quantity of ice, the chute lower end is opened for one of a plurality of different time periods, where each individual time period of the plurality is of a duration to dispense from the chute an associated predetermined quantity of ice. In response to dispensing ice from the chute, an agitator in the bin is operated for one of a plurality of different time periods, where each individual time period of the plurality is of a duration to move through the bin outlet passage and into the upper end of the chute an amount of ice substantially equal to that dispensed. The ice dispensing system is provided with an improved user interface and user programmable features.

  • Publication number: 20100226201
    Abstract: A multiple piece agitator for an ice dispenser, which could also include a beverage dispenser, having an ice bin with a limited access opening, is disclosed. The multiple piece agitator can be easily field disassembled within the dispenser's ice bin, then the agitator disassembled pieces removed for cleaning or servicing of the ice bin in which the agitator moves and/or for cleaning or servicing the agitator. The invention lessens the need to remove any icemaker, usually fitted to the ice dispenser, before servicing of the ice bin and/or agitator.

  • Patent number: 6808091
    Abstract: A dispensing nozzle includes an outer housing defining an interior and a nozzle outlet. A mixing nozzle insert is positioned within the nozzle housing. The insert has a central elongate core that includes a top end that is positioned adjacent inlets for water and juice concentrate, and a bottom end opposite there from adjacent the outlet of the nozzle. The insert includes a concentrate disk on its top end having a perimeter edge positioned closely adjacent an interior surface of the nozzle housing. This disk includes one or more flow holes extending there through. The insert also includes, below the concentrate disk, a plurality of mixing projections having alternating extensions integral with the central core and extending outward there from along the length thereof. The insert and the nozzle housing are designed so that the syrup concentrate is introduced above the concentrate disk and the water is introduced at a level just below the concentrate disk.
