Claim 8:
9. The apparatus of claim 1, wherein the gas injector comprises a nozzle disposed above the fluid chamber, and wherein the nozzle is configured to inject the gas stream transversely to the surface of the freezing liquid contained in the fluid chamber, and wherein the apparatus further comprises:
a solenoid valve controlling gas flow to the nozzle and configured to switch between a closed position to shut-off the gas stream from reaching the nozzle and an open position to permit the gas stream to reach the nozzle;
a sensor configured to generate a signal relating to a position of the transporter; and
a control unit in electrical communication with the sensor and the solenoid valve, wherein the control unit is configured to receive the signal from the sensor and transmit a command to the solenoid valve to switch between the open and closed positions based on the signal.
