Abstract
A beverage machine system that includes: an insulated potable liquid storage tank having an interior volume; a liquid carbonator spaced within the interior volume of the insulated potable liquid storage tank and submerged therein; a high pressure potable liquid pump configured to pump potable liquid from the interior volume of the insulated potable liquid storage tank through a potable liquid conduit to a spray nozzle within an interior volume of the liquid carbonator; and a cooling coil positioned in a spaced apart relationship but wound around the carbonator such that the cooling coil does not physically touch an exterior surface of the carbonator submersed within the chilled potable liquid and the space between the cooling coil and the carbonator is at least substantially free of any other structure other than periodic frozen potable liquid adjacent the cooling coil.
