A reconstituting device including a control system reconstitutes product concentrates. The reconstituting device is further able to pre-wet a mixing device of the dispense circuit, dispense the reconstituted product, and rinse the mixing device during a dispense interval without affecting the mix ratio of the reconstituted dispense. Pre-wetting and rinsing of the mixing device of the dispense circuit is accomplished by moving a portion of a concentrate dispense from an earliest and a latest dispense interval to a mid-range dispense interval, thereby flowing reconstituting fluid alone during the earliest and latest dispense intervals. Pre-wetting allows the reconstituting fluid to form a boundary layer on contact surfaces of the mixing device. Rinsing is accomplished by flowing reconstituting fluid through the mixing device after the mixing sequence of the dispense is completed. The control system may conduct the pre-wet or the post-rinse sequence, or may conduct both within a same dispense.

I claim: 1. A reconstituting apparatus, comprising: a mixing device; and a control system whereby, during a dispense interval, the control system regulates delivery of a product concentrate from a product concentrate source and a reconstituting fluid from a reconstituting fluid source to the mixing device, further whereby the control system commences the dispense interval by delivering the reconstituting fluid for a predetermined interval before the product concentrate, thereby pre-wetting the mixing device. 2. The reconstituting device according to claim 1, whereby, during the dispense interval, the control system delivers the product concentrate and the reconstituting fluid upon the expiration of the predetermined interval. 3. The reconstituting apparatus according to claim 2, whereby the control system ends the dispense interval by stopping the delivery of the reconstituting fluid and the product concentrate. 4. The reconstituting apparatus according to claim 2, whereby, during the dispense interval, the control system stops the delivery of the product concentrate and continues the delivery of the reconstituting fluid for a predetermined interval, thereby rinsing the mixing device, further whereby the control system ends the dispense interval by stopping the delivery of the reconstituting fluid. 5. The reconstituting apparatus according to claim 1, wherein the mixing device forces interaction between the product concentrate stream and the reconstituting fluid stream, thereby reconstituting the product concentrate. 6. The reconstituting apparatus according to claim 5, wherein the product concentrate is reconstituted interior to the mixing device. 7. The reconstituting apparatus according to claim 5, wherein the product concentrate is reconstituted exterior to the mixing device. 8. A reconstituting apparatus, comprising: a mixing device; and a control system that regulates delivery of a product concentrate from a product concentrate source and a reconstituting fluid from a reconstituting fluid source to the mixing device, whereby, during a dispense interval, the control system: delivers the product concentrate and the reconstituting fluid, stops the delivery of product concentrate and continues the delivery of the reconstituting fluid for a predetermined interval, thereby rinsing the mixing device, and stops the delivery of the reconstituting fluid, thereby ending the dispense interval. 9. The reconstituting apparatus according to claim 8, whereby the product concentrate and the reconstituting fluid delivered during the dispense interval form a reconstituted product. 10. The reconstituting apparatus according to claim 2, whereby the product concentrate and the reconstituting fluid delivered during the dispense interval form a reconstituted product. 11. The reconstituting apparatus according to claim 8, wherein the mixing device forces interaction between the product concentrate stream and the reconstituting fluid stream, thereby reconstituting the product concentrate. 12. The reconstituting apparatus according to claim 11, wherein the product concentrate is reconstituted interior to the mixing device. 13. The reconstituting apparatus according to claim 11, wherein the product concentrate is reconstituted exterior to the mixing device. 14. A product dispenser, comprising: a housing; a mixing device disposed within the housing; and a control system, whereby, during a dispense interval, the control system regulates delivery of a product concentrate from a product concentrate source and a reconstituting fluid from a reconstituting fluid source to the mixing device, further whereby the control system commences the dispense interval by delivering the reconstituting fluid for a predetermined interval before the product concentrate, thereby pre-wetting the mixing device. 15. The product dispenser according to claim 14, whereby, during the dispense interval, the control system stops the delivery of the product concentrate and continues the delivery of the reconstituting fluid for a predetermined interval, thereby rinsing the mixing device, further whereby the control system ends the dispense interval by stopping the delivery of reconstituting fluid. 16. A product dispenser, comprising: a housing; a mixing device disposed within the housing; and a control system that regulates delivery of a product concentrate from a product concentrate source and a reconstituting fluid from a reconstituting fluid source to the mixing device, whereby, during a dispense interval, the control system: delivers the product concentrate and the reconstituting fluid, stops the delivery of the product concentrate and continues the delivery of the reconstituting fluid for a predetermined interval, thereby rinsing the mixing device, and stops the delivery of the reconstituting fluid, thereby ending the dispense interval. 17. A method of cleansing a mixing device during a dispense, comprising: a. commencing a dispense interval by flowing for a predetermined interval a reconstituting fluid through a mixing device to wet the interior surfaces of the mixing device; b. flowing a product concentrate through the mixing device at the expiration of the predetermined interval to interact with the reconstituting fluid and reconstitute the product concentrate; and c. stopping the flows of the reconstituting fluid and the product concentrate, thereby ending the dispense interval. 18. The method of cleansing a mixing device during a dispense according to claim 17, wherein step c. is replaced with: c. stopping the flow of the product concentrate through the mixing device, such that the flowing reconstituting fluid rinses the interior surfaces of the mixing device to provide a cleansing function; and d. stopping the flow of the reconstituting fluid after a predetermined interval, thereby ending the dispense interval. 19. A method of cleansing a mixing device during a dispense, comprising: a. flowing a reconstituting fluid through a mixing device; b. flowing a product concentrate through the mixing device to interact with the flow of reconstituting fluid and create a reconstituted product; c. stopping the flow of the product concentrate through the mixing device, such that the flowing reconstituting fluid rinses the interior surfaces of the mixing device to provide a cleansing function; and d. stopping the flow of the reconstituting fluid after a predetermined interval, thereby ending a dispense interval.
