<p>A multiple beverage dispensing nozzle includes a dispensing array 10 with a plurality of flow-paths 12, 13 for a beverage base and for additives, attached to an isolation device 17 within a dispensing nozzle. The dispensing array facilitates flow of a beverage base and at least one beverage additive into the dispensing nozzle; the dispense point isolation device isolates discharge of beverage additive to prevent cross-contamination and color-carryover caused by the residual traces of additive and has vertical flow-path outlets for thebeverage additives. In many embodiments, the dispense point isolation device further includes one or more isolation features, including any or all of a recess, trough, notch, raised ridge or tubular projection around an exit orifice of the beverage additive flow channel so as to further isolate release of the beverage additive and further inhibit cross-contamination and color-carryover.</p> |
