  • Patent number: 5025840
    Abstract: An ice cream dispensing machine having at least one storage container for storing liquid ice cream. The storage container is connected to a freezing cylinder that contains a mixing spiral. The freezing cylinder is connected to a dispensing apparatus that includes a vertically movable ice cream cornet holder. Cornet position sensing switches are employed to initiate machine operations. Timing clocks control the dispensing of the ice cream and provide a safety factor with respect to the maximum quantity of ice cream that can be dispensed during a single dispensing operation. The time interval between two successive dispensing operations is controlled to insure that sufficient time has elapsed for complete freezing of the liquid ice cream for the next dispensing operation.
