The present invention relates to a palatability stabilizer for maintaining properly carbonated water in an electrically powered postmix fountain drink dispensing system when a supply of pressurized carbon dioxide is depleted. A carbon dioxide pressure sensor is connected between the carbon dioxide supply and the fountain drink dispensing system to sense the carbon dioxide supply pressure. A switch is connected to the carbon dioxide pressure sensor and coupled between the electrical power and the fountain drink dispensing system for disconnecting power to the fountain drink dispensing system when the carbon dioxide pressure is below a predetermined pressure. This is done so that water is not improperly carbonated with low pressure carbon dioxide and so that properly carbonated water and other drink components within the fountain drink system are maintained in the system by not dispensing fountain drinks until the pressurized carbon dioxide supply is replenished. Thus, the palatability of fountain drinks which are dispensed is stabilized without the need to clean out the entire system upon replenishing the carbon dioxide supply.

A palatability stabilizer for use in a postmix fountain machine of the type requiring connection to a pressurized carbon dioxide supply, a water supply, and a drink flavor supply and of the type having a carbonator for connection to said carbon dioxide supply through a carbon dioxide supply line and for connection to said water supply through a water supply line, said carbonator for producing carbonated water, a mixing valve for connection to said flavor supply and connected to said carbonator for mixing a carbonated fountain drink prior to dispensing it, and an electrical power source connected to said carbonator and said mixing valve, said palatability stabilizer comprising: (a) carbon dioxide pressure actuated means connected to said carbon dioxide supply line and to said power source for automatically disconnecting power to said carbonator and said mixing valve when the carbon dioxide pressure is below a predetermined carbon dioxide pressure, wherein said carbon dioxide pressure actuated means for disconnecting power further comprises: (i) a carbon dioxide pressure-sensing electrical switch attached to said carbon dioxide supply line for sensing pressure therein between said carbon dioxide supply and said carbonator, and (ii) at least one relay electrically connected to said electrical power source through said carbon dioxide pressure switch for activation thereby, said relay having means therein for disconnecting power from said carbonator and said mixing valve when said relay is activated by said carbon dioxide pressure switch, thereby disabling the drink machine with properly proportioned drink components therein before the carbonated water in said carbonator is inadequately carbonated; and (b) water pressure actuated means connected to said water supply line and to said power source for automatically disconnecting power to said carbonator and said mixing valve when the water pressure is below a predetermined water pressure.
