Abstract
A mobile beverage dispenser comprises a wheelable platform having mounted thereon a chillable chamber connected to a refrigerated cooling coil for removing heat from a beverage in a bulk storage container placed therein for cooling; and a beverage dispensing tap connectable to the container in fluid communication with the beverage, and mounted in thermally conductive relationship with the chillable chamber, whereby the chamber when chilled removes heat from the dispenser in preparation for dispensing of the beverage, by virtue of the conductive relationship.
Claims8
A mobile beverage dispenser comprising:
- a. a wheelable platform having mounted thereon a refrigeration plant, adapted for removing heat from a bulk storage container being borne on the platform and containing a beverage for cooling;
- and
- b. a beverage dispensing tap, connectable to the container, in fluid communication with the beverage, and mounted in thermally conductive relationship with the refrigeration plant,
- whereby the refrigeration plant removes heat from the dispenser in preparation for dispensing of the beverage, the refrigeration plant comprises:
- a receptacle wherein the container is receivable for cooling an external surface of the container;
- an evaporative cooling coil operatively located against and in thermally conductive relationship with a wall of the receptacle
- a refrigerant expansion chamber connected in thermally conducting relationship with a tubular conduit wherein the cooling coil is located on the outside of the receptacle wall,
- wherein the dispensing tap includes the tubular conduit passing through the receptacle wall;
- and
- wherein tubing through which refrigerant from the refrigerant plant flows is configured for selectively bypassing the expansion chamber.
A method of dispensing a chilled beverage, the method comprising the steps of:
- a. providing chiller apparatus including:
- i. a chilling receptacle adapted for receiving therein in cooling relationship a bulk storage beverage container containing a beverage for dispensing, and
- ii. a conduit connected to a dispensing tap, wherein the conduit and tap are in thermally conductive relationship with the chilling receptacle,
- wherein the chiller apparatus comprises a refrigerated cooling coil arranged in thermal contact with an outside surface of a wall of the receptacle,
- b. operating the apparatus to cause the receptacle to be cooled and to draw heat from the conduit and tap,
- c. placing the beverage container in the receptacle and allowing the container and its contents to cool,
- d. connecting the container and tap in fluid communication,
- e. operating the tap to dispense cooled beverage through the tap via the pre-cooled conduit, the conduit passes through the wall of the receptacle, and
- f. including causing refrigerant selectively to bypass the expansion chamber when cooling of the conduit is not required,
- wherein the chiller apparatus further comprises a refrigerant expansion chamber connected in thermally conducting relationship with the conduit.
A mobile beverage chiller comprising a chillable receptacle mounted on a wheelable platform, the receptacle adapted for receiving a bulk beverage dispensing container, a chilling device operatively mounted in thermally conductive contact with the receptacle, and beverage dispensing tap operatively connectable to the container and in thermally conductive relationship with the receptacle;
- wherein the dispensing tap is in thermally conductive contact with a refrigerant expansion chamber connected to the chilling device;
- and
- a controllable bypass circuit operable to cause refrigerant to bypass the chamber.
