METHOD AND APPARATUS FOR CLEANSING A MIXING DEVICE

摘要

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 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.
