Countertop hot and cold post-mix beverage dispenser

Abstract

A beverage dispense system for a countertop having a water inlet including a solenoid valve and a beverage concentrate inlet to which a bag-in-box containing a supply of liquid coffee concentrate is attached. A beverage dispense font is mounted on the countertop. A water conduit connects the water inlet with the dispense font. A separate liquid beverage concentrate conduit connects the beverage concentrate inlet with the beverage dispense font. An electric syrup pump pumps liquid coffee concentrate from the bag-in-box to the end of the dispense font. A control unit controls the separate delivery of water from the mains water inlet and/or liquid coffee concentrate to the end of the beverage dispense font. Where water and liquid coffee concentrate are delivered, they will mix in the beverage receptacle.
