Definitions

  • the present invention relates to apparatuses, methods and processes for cooling and dispensing beverages.
  • Draught beverages in restaurants, bars, stadiums and other public facilities are dispensed using systems that consist of a storage container that is kept cool in a remote refrigerator.
  • a cooled supply line takes the beverage to a dispensing faucet.
  • the beverages are stored in containers that are kept in remote walk-in refrigerators that are also used to chill foods as required by the facility's kitchen. Drinks may be dispensed at a location several hundred feet away from the storage container.
  • the beverage trunk line used to transport the beverage to the dispensing tap is generally made up of a multi-line insulated construction that contains two central cooling liquid lines that will bring a cold glycol/water mixture or ice water to the dispensing faucet and back to maintain the beverage's temperature.
  • This system has the drawback of providing inconsistent cooling performance. This is due to the fact that the temperature inside the walk-in cooler can fluctuate widely as personnel enter and exit during busy times. Also, the beverage trunk line can travel through areas of varying ambient temperatures thereby raising the beverage temperature.
  • This fraction of the beverage will mix with any warm beverage that is found between the heat exchanger and the tap. It will also mix with beverage that passes quickly through the heat exchanger with a limited or no dwell time. This results in a beverage being served at temperatures warmer than desired. There is therefore a need for a beverage dispensing apparatus that dispenses cold beverage servings even where the beverage must be delivered over a significant distance and where there are significant periods of time between consecutive pours.
  • the present invention provides a method and apparatus for delivering a beverage under pressure through a distribution conduit to a dispensing means.
  • the beverage is preferably a carbonated beverage and most preferably is beer.
  • the apparatus of the present invention has a heat exchanger and a reservoir. The beverage is transmitted through a conduit from a container through the heat exchanger and the reservoir to a dispensing means.
  • the reservoir holds a quantity of cooled beverage.
  • the reservoir is preferably in contact with a source of cooling for providing additional cooling between such dispensing events.
  • an apparatus for delivering a beverage under pressure from a container to a dispensing means comprising a trunk line including a beverage conduit for delivering the beverage from the container, the trunk line further including a coolant fluid conduit connected to a source of coolant fluid for delivering the coolant fluid; a heat exchanger defining an inlet for receiving the coolant fluid conduit and an outlet for the coolant fluid conduit, the heat exchanger further defining an inlet for receiving the beverage conduit, an outlet for the beverage conduit and a heat exchanging surface for heat exchange between the beverage and the coolant fluid; and a reservoir for holding a quantity of the beverage, the reservoir being connected to the heat exchanger, the reservoir defining an inlet for receiving the beverage and a beverage outlet.
  • an apparatus for delivering a beverage under pressure from a container to a dispensing means comprising:
  • a heat exchanger defining a first passageway having an inlet and an outlet through which the beverage may be delivered, the heat exchanger further defining a second passageway having an inlet and an outlet for delivering a coolant fluid through the heat exchanger in sufficient proximity to the first passageway to permit heat exchange between the coolant fluid and the beverage; a tank for holding a quantity of a coolant fluid;
  • a reservoir for holding a quantity of the beverage, the reservoir being located in the tank for submersion in said coolant fluid, the reservoir defining an inlet and an outlet and a passageway between the inlet and the outlet;
  • a first conduit for delivering the beverage from the container to the inlet of the first passageway of the heat exchanger
  • a second conduit for delivering beverage from the outlet of the heat exchanger to the inlet of the reservoir
  • a third conduit for delivering beverage from the reservoir to the dispensing means.
  • an apparatus for delivering a beverage under pressure from a container to a dispensing means comprising:
  • a housing defining a chamber for holding a quantity of a coolant fluid, the housing further defining an inlet and an outlet;

  • a beverage conduit communicating between the container, the heat exchanging means, the reservoir and the dispensing means to define a beverage flow path from the container through the heat exchanging means and the reservoir to the dispensing means;
  • a coolant fluid conduit for communicating between the heat exchange means and the source of coolant fluid to define a flow path between the heat exchange means and the source of coolant fluid.
  • a method for delivering a beverage under pressure through a distribution line to a dispensing means involves providing a source of beverage under pressure. The method involves delivering the beverage through a heat exchanger and then delivering the beverage to a reservoir that is submerged in a coolant fluid. The method involves storing the beverage in the reservoir and then dispensing the beverage from the reservoir through a dispensing means.
