Abstract
An insulated container that is open on top and contains phase change material travels along a conveyor. The container initially stops under an infrared sensor whereat its initial interior temperature is determined. A microprocessor uses the temperature data to determine the amount of cryogenic liquid that must be added to the container so that its phase change material will be frozen to a predetermined temperature. A cryogenic liquid dispenser charges the container with an amount of cryogenic liquid determined by the microprocessor. The cryogenic liquid dispenser includes a phase separator which depressurizes cryogenic fluid received from a bulk storage tank. Once the container is charged, it may be loaded with perishables, examples of which include food, blood or chemicals.
