Abstract: A carbonation system for a soft drink dispenser in which water is precooled and then introduced into an insulated tank where it is subjected to pressurized carbon dioxide. A pressure transducer monitors the pressure within the tank, with the dispensing of soda from the tank being regulated on a timed basis as a function of such pressure. The tank is periodically emptied and refilled to assure that the soda generated therein is fresh.

Abstract: A soft drink dispenser capable of rapidly dispensing carbonated beverages with minimized foaming action. The syrup and soda are dispensed separate from each other and allowed to mix upon the ice in a cup placed beneath the dispensing head. The dispensing of the syrup and soda is staged to minimize foaming while achieving optimum beverage taste. Syrup is dispensed from individual pumps which communicate with a bulk supply. The syrup is consolidated in the pumps, preventing waste or the introduction of "slugs" into the dispensing line. The temperature of the syrup is monitored and compensation is made during the dispensing cycle to accommodate changes in viscosity. In generating soda, water is precooled and then introduced into an insulated tank where it is subjected to pressurized carbon dioxide. In the pour head, a cluster of soda orifices are peripherally encompassed by syrup orifices, certain of which are angled to cause the syrup to convolute the stream of soda.

Abstract: A syrup dispensing system in which a pump is actuated at a preset clock rate under a fixed pressure head. The clock rate and pressure head are tailored to accommodate the lowest operating temperature for the system and, accordingly, the thickest syrup. A preset amount of syrup is dispensed on each clock cycle such that a constant rate of syrup flow is attained.

Abstract: A carbonation system employing a pneumatic pump which operates off of a pressurized source of carbon dioxide which is itself employed for the carbonation process. The pneumatic pump serves as both a precarbonation chamber and a reservoir for receiving water from a low pressure source and subsequently transferring precarbonated water to a carbonation tank. Sensors within the pneumatic pump assure that a proper volume of water is maintained within the precarbonation chamber and available for transfer to the tank. Both the pneumatic pump and the carbonation tank operate off of the same supply of pressurized carbon dioxide, but the pressure provided to the tank is slightly less than that presented to the pneumatic pump.
