A cryogenic freezer includes a plurality of conveyor rail supports that rest upon side walls of a lower housing of the freezer. The conveyor rail supports include upper and lower bars that support upper and lower conveyor support rails extending perpendicular to the bars.

In one embodiment, a method of forming frozen ice cream pellets includes supplying an ice cream premix into a loading vessel; loading a loading cylinder with the ice cream premix from the loading vessel, the loading cylinder being connected to the loading vessel; applying a machine-controllable force to expel the ice cream premix from the loading cylinder as ice cream premix pellets; and exposing the ice cream premix pellets to a cryogenic fluid, thereby at least partially freezing the ice cream premix pellets.

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.

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an immersion bath having a recirculating flow of liquid nitrogen thereinside and at least partially frozen material is withdrawn from the bath downstream of where it is fed.

Recirculating liquid nitrogen immersion bath and method for freezing a product therein

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.

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

Shelling of cooked eggs

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.

A liquid additive is sprayed over liquid nitrogen to form discrete solid particles of the additive in liquid nitrogen. The mixture of additive particles and liquid nitrogen is mixed with a flow of liquid nitrogen at an eductor pump to provide a food treatment composition comprising additive particles. The food treatment composition flows into an interior of food processing equipment to come into contact with food items contained therein.
