Abstract: A method of proportionally mixing two fluids is provided. The method includes introducing a first fluid stream, introducing a second fluid stream, wherein the flow rate of the second stream is modulated by a valve, thereby producing a modulated stream, combining the first fluid stream and the second fluid stream, thereby forming a compounded fluid stream, introducing said compounded fluid stream into a fluid containment region, wherein a vapor fraction and a liquid fraction are formed, determining the composition of the vapor fraction, comparing the composition of the vapor fraction with a predetermined composition to determine a composition error, and modulating the valve to reduce the composition error to a predetermined error.

Abstract: A material to be frozen is fed to an immersion bath having a recirculating flow of liquid nitrogen thereinside and at least partially frozen material is withdrawn from the bath downstream of where it is fed.

Abstract: In another embodiment of the invention, a method for reducing boil-off gas losses from a liquid storage tank having a liquid and boil-off gas contained therein is provided. In one embodiment, the method can include the steps of pumping the liquid from the liquid storage tank to a heat exchanger using a liquid pump; subcooling the liquid within the heat exchanger by using cold energy from vaporization of liquid nitrogen to form a subcooled liquid; and introducing the subcooled liquid to the liquid storage tank, thereby reducing the temperature within the liquid storage tank.

Abstract: A method and apparatus for recovering boil-off gas from a head space of a liquid storage tank having a fluid contained therein is provided. The method can include the steps of withdrawing the boil-off gas from the storage tank and introducing said boil-off gas to a heat exchanger using a vapor flow inducer; cooling the boil-off gas in the heat exchanger by using cold energy from vaporization of liquid nitrogen to form a cooled fluid; and introducing the cooled fluid to the liquid storage tank, thereby reducing the temperature within the liquid storage tank.

Abstract: Embodiments of the invention generally provide methods and systems that distribute an additive in solid carbon dioxide in an interior of food processing equipment. The additive may be injected into a flow of liquid carbon dioxide upstream of an expander at or adjacent to the interior. Injection of the additive into the interior may be alternated with directing a flow of expanded carbon dioxide into the interior. In some embodiments, the freezing point of the additive with or without a diluent composition and/or additive(s) is lower than a temperature of the liquid carbon dioxide.

Abstract: An improved process for peeling hard boiled eggs includes contacting the cooked egg with a cold inert gas before peeling.

Abstract: Systems and methods compress, freeze and store forms at sufficiently low temperatures. A system provides a storage tank of liquefied gas, a gas-liquid separation tank, and a compression chamber. The compression chamber provides compression plates chilled by flow of liquefied gas through conduits traversing an interior volume of the plates. The method comprises recirculating liquefied gas to improve cooling efficiency while lowering operation costs. The system and method further provide for integrated measurement and control of the flow of liquefied gas through the primary components of the system. In one embodiment, the forms are rubber cylinders utilized in the production of torsion axles.
