Rapid fluid freezing device
View Patent ↗The present invention provides a method and apparatus for freezing an alcoholic beverage, including placing an alcoholic beverage into a beverage receptacle; dispensing a predetermined amount of the alcoholic beverage into a plurality of freezing cavities; transferring liquid nitrogen from a coolant reservoir to a plurality of coolant chambers; exposing the plurality of freezing cavities to the liquid nitrogen to freeze the alcoholic beverage; and removing the frozen alcoholic beverage from the freezing chamber.
1. A device for rapidly freezing a liquid, the device comprising:
a coolant reservoir;
a plurality of stationary coolant chambers in fluid communication with the coolant reservoir;
a first beverage receptacle configured to receive the liquid; and
a plurality of freezing cavities in fluid communication with the first beverage receptacle, at least a portion of each freezing cavity being positioned within and in thermal communication with one of the coolant chambers, each coolant chamber being fluidly isolatable from another coolant chamber;
a sensor disposed between the first beverage receptacle and the freezing cavities configured to measure the amount of coolant flowing between the first beverage receptacle and the freezing cavities; and
the plurality of freezing cavities being configured to freeze solid the liquid after being received within the first beverage receptacle.
2. The device according to claim 1 , further comprising at least one of a valve, pump, and regulator in fluid communication with the coolant reservoir for selectively dispensing a coolant from the reservoir to each coolant chamber.
3. The device according to claim 2 , further comprising at least one of a valve, pump, and regulator in fluid communication with the beverage receptacle for selectively dispensing a fluid from the beverage receptacle to at least one of the freezing cavities.
4. The device according to claim 3 , further comprising a user interface for allowing selective operation of at least one of the first and second fluid handling components.
5. The device according to claim 4 , wherein the user interface includes a liquid crystal display.
6. The device according to claim 4 , wherein the sensor is one of a temperature sensor, pressure sensor, and flow sensor in electrical communication with the user interface.
7. The device according to claim 1 , further comprising a dispensing mechanism coupled to each freezing cavity to dispense the frozen solid liquid of each freezing cavity.
8. The device according to claim 1 , further comprising a plurality of beverage receptacles.
9. The device of claim 1 , wherein the liquid is alcohol, and wherein the plurality of freezing cavities are configured to at least freeze solid the liquid to at least −40° C.
