Some embodiments of the present invention provide a comestible fluid dispensing apparatus including a nozzle defining an interior space and having a fluid inlet through which fluid is received within the interior space and a fluid outlet through which fluid exits the interior space and a substantially conical valve movable relative to the nozzle between different positions with respect to the nozzle and shaped to reduce turbulence and/or provide improved dispensing control.
Abstract:
A nozzle assembly is disclosed which is capable of controlling pressure of comestible fluid exiting the nozzle assembly. To provide comestible fluid at rack pressure to the nozzle of the nozzle assembly, the nozzle can be provided with a valve movable through a number of closed positions to change pressure within the nozzle. Prior to fluid dispense, pressure at the nozzle is preferably reduced by increasing a volume within the nozzle assembly, such as by actuating the valve through its range of closed positions.
Abstract:
Preferred embodiments of the present invention have a nozzle assembly capable of controlling pressure of comestible fluid exiting the nozzle assembly, a refrigeration system in which refrigerant pressure and temperature is controllable to enable control of comestible fluid temperature, heat exchangers connected to cool comestible fluid in the nozzles, an ultraviolet sterilization system for sterilizing locations outside and inside the system, and a hand held comestible fluid dispenser capable of cooling and selectively dispensing one of several comestible fluids supplied thereto. To improve temperature control and cooling efficiency, the present invention preferably employs heat exchangers adjacent to the nozzle assemblies. The present invention can take the form of a multi-fluid dispensing gun having such a nozzle and heat exchanger relationship and having the pressure controlling valve as described above. To further improve control of comestible fluid temperature, the present invention preferably has an evaporator pressure regulator to control refrigerant pressure upstream of the refrigeration system compressor and a hot gas bypass valve to control refrigerant temperature.

Preferred embodiments of the present invention have a nozzle assembly capable of controlling pressure of comestible fluid exiting the nozzle assembly, a refrigeration system in which refrigerant pressure and temperature is controllable to enable control of comestible fluid temperature, heat exchangers connected to cool comestible fluid in the nozzles, an ultraviolet sterilization system for sterilizing locations outside and inside the system, and a hand held comestible fluid dispenser capable of cooling and selectively dispensing one of several comestible fluids supplied thereto. To provide comestible fluid at rack pressure to the nozzles in one highly preferred embodiment, each nozzle preferably has a valve movable through a number of closed positions to change pressure within the nozzle. Prior to fluid dispense, pressure at the nozzle is preferably reduced by actuating the valve through its range of closed positions. To improve temperature control and cooling efficiency, the present invention preferably employs heat exchangers adjacent to the nozzle assemblies. Due to their locations close to the nozzle assemblies, the heat exchangers generate convective recirculation through the nozzle assemblies to cool comestible fluid to the discharge openings thereof. The present invention can take the form of a multi-fluid dispensing gun having such a nozzle and heat exchanger relationship and having the pressure controlling valve as described above. To further improve control of comestible fluid temperature, the present invention preferably has an evaporator pressure regulator to control refrigerant pressure upstream of the refrigeration system compressor and a hot gas bypass valve to control refrigerant temperature.
Abstract:
Apparatus and method for cooling a comestible fluid. The method can include cooling a plate with ice. A heat pipe with a condenser portion can be in heat transfer relationship with the plate, and an evaporator portion can be in heat transfer relationship with the comestible fluid. Heat can be transferred from a comestible fluid to the plate through the heat pipe.
Abstract:
A beverage dispenser for carbonated beverages, such as draft beer and soda, includes a volumetric beverage flow rate controller in the form of a tubular restrictor or choker combined with a subsurface flow beverage dispensing nozzle assembly. The nozzle has a positive bottom shut-off moveable between open and closed positions for initiating and stopping flow into the container. At defined rates of serving speed, greater control over pour characteristics, particularly over foam formed on the top of the beverage, is achieved.
Abstract:
A beverage dispenser for dispensing a carbonated beverage from a beverage source into a receptacle includes a housing defining an interior volume and having a first surface proximal to the beverage source and a second surface distal to the beverage source. The beverage dispenser further includes a conduit in fluid communication with the beverage source entering the first surface of the housing and terminating proximate the second surface of the housing. The dispenser also includes a multi-nodal flow rate controller disposed within the interior volume of said housing in contact with said conduit and a subsurface dispensing nozzle in fluid communication with the terminal end of the conduit. The flow through the conduit to the subsurface dispensing nozzle is compensated to maintain substantially hydraulic beverage flow within the conduit by adjusting the contact between the multi-nodal flow rate controller and the conduit.
Abstract:
An apparatus for controlling beverage flow includes a dispensing tube having a distal end. The apparatus also includes a ball plug configured for linear reciprocal motion between a first position and a second position so that the ball plug abuts the distal end of the dispensing tube in the first position and is separated from the distal end of the dispensing tube in the second position. A flow rate controller for compensation of flow in a fluid dispensing system includes a body portion and a first set of flow restricting nodes and a second set of flow restricting nodes formed in the body portion. The controller also includes a first channel formed in the body portion and configured to receive and partially surround a portion of a first fluid conduit such that the first fluid conduit is in contact with the first set of flow restricting nodes. The controller also includes a second channel formed in the body portion and configured to receive and partially surround a portion of a second fluid conduit such the second fluid conduit is in contact with the second set of flow restricting nodes. Flow through the first fluid conduit is compensated by adjusting the contact between the first set of flow restricting nodes and the first fluid conduit, and flow through the second fluid conduit is compensated by adjusting the contact between the second set of flow restricting nodes and the second fluid conduit.
Abstract:
A beverage dispenser for dispensing a carbonated beverage from a beverage source into a receptacle. The dispenser includes a first housing defining an interior volume and having a first surface closer to the beverage source and a second surface further from the beverage source. The dispenser also includes a beverage cooler including a second housing having a top surface, a bottom surface, and sides defining an interior volume. A first circuit is disposed within the interior volume of the second housing and forms a first set of fluid flow paths. A second circuit is disposed within the interior volume of the second housing and forms a second set of fluid flow paths in parallel with the first set of fluid flow paths. A third circuit is disposed within the interior volume of the second housing and forms a third set of fluid flow paths in parallel with the first and second sets of fluid flow paths, wherein, the first, second, and third circuits defines an inlet and an outlet. The beverage dispenser also includes a first tubing in fluid communication with the beverage source entering the second housing and coupled to the inlet of the first, second, and third circuits. In addition, the beverage dispenser includes a second tubing coupled to the outlet of each of the first, second, and third circuits and entering the first surface of the first housing and terminating proximate the second surface of the first housing. The beverage dispenser also includes a multi-nodal flow rate controller disposed within the interior volume of the first housing in contact with the second tubing, and a subsurface dispensing nozzle in fluid communication with the terminal end of the second tubing.
