Abstract

Beverage dispensing apparatus, systems, and related methods are provided that have a recirculation loop to cool fluids in a dispensing tube bundle that delivers beverage fluids to a beverage dispensing assembly. A beverage dispensing apparatus includes an adjustable bypass manifold having an adjustable flow restriction that is configurable to enable the use of the beverage dispensing apparatus with different chilled soda recirculation systems. The adjustable bypass manifold includes ports for connection to the recirculation loop and ports for connection to a soda recirculation system.

First claim

What is claimed is:

1. A method for cooling beverage fluids in supply lines conveying the beverage fluids to a dispensing assembly, the method comprising:
receiving a first flow of a cooling fluid from a cooling fluid source;
dividing the first flow of the cooling fluid into a second flow and a third flow by using an adjustable flow restriction to control a flow rate of the third flow, the adjustable flow restriction having an open position and a closed position, the flow rate of the third flow being greater than zero at both the open position and the closed position of the adjustable flow restriction;
circulating the second flow of the cooling fluid through a recirculation loop; and
returning at least a portion of the third flow to the cooling fluid source without circulating the third flow through the recirculation loop.

2. The method of claim 1 , further comprising absorbing heat into the cooling fluid in the recirculation loop to cool the beverage fluids in the supply lines.

3. The method of claim 1 , further comprising dispensing a portion of the first flow of the cooling fluid from the dispensing assembly, the cooling fluid being a beverage fluid.

4. The method of claim 1 , further comprising controlling a flow rate of the second flow of the cooling fluid through the recirculation loop via a valve assembly to inhibit formation of condensation.

5. The method of claim 4 , further comprising maintaining the flow rate of the second flow at approximately 5 ml per second via a dynamic flow regulator coupled to the valve assembly.

6. The method of claim 4 , further comprising maintaining the flow rate of the second flow at approximately 5 ml per second via a flow restrictor coupled to the valve assembly.

7. The method of claim 1 , further comprising maintaining a flow rate of the second flow at a substantially constant flow rate via a flow restrictor.

8. The method of claim 7 , wherein the flow rate of the second flow of the cooling fluid through the recirculation loop is approximately 5 ml per second.

9. The method of claim 1 , further comprising maintaining a flow rate of the second flow at a substantially constant flow rate via a dynamic flow regulator.

10. The method of claim 9 , wherein the flow rate of the second flow of the cooling fluid through the recirculation loop is approximately 5 ml per second.

11. The method of claim 1 , wherein a flow rate of the first flow is 50 to 100 gallons per hour at a supply pressure of 75 psi to 110 psi when the adjustable flow restriction is in the open position.

12. The method of claim 1 , wherein a flow rate of the first flow is 5 to 10 gallons per hour at a supply pressure of 50 psi to 75 psi when the adjustable flow restriction is in the closed position.
