<p>A post mix beverage dispense apparatus has a mixing head 10 arranged to receive different combinations of a concentrate and a diluent for dispensing any selected one of a range of beverages. The concentrates are delivered to the head 10 in dedicated flow lines 14, 16, 18, 20 under the control of respective valves 22, 24, 26, 28 actuated via a control board 52 in response to user selection of a desired beverage at a control panel 50. The diluent is delivered to the head 10 in a flow line 30 under the control of a changeover valve 32 for selectively correcting sources of different diluents to the flow line 30 via the control board 52 in response to user selection of the desired beverage at the control panel 50. The changeover valve 32 is positioned close to the mixing head 10 to minimise the volume of diluent remaining between the valve 32 and the head 10 after dispense. In a preferred arrangement, a control valve 38 is provided between the changeover valve 32 and the head 10 for providing a metered flow of diluent.</p> |
