摘要： A cryogenic tunnel freezer (10) having modular design and construction including a lower section (16) that can be raised and lowered relative to an upper section (14), the upper and lower sections (14, 16) defining a tunnel (12) when the lower section (16) is in a closed (raised) position. Product is moved through the tunnel (12) via a belt (22) formed of arrays of plastic modules (76) that are reinforced by metal chains (140) and rods (150). The lower run (23) of the belt (22) rides on the floor (48) of the lower section (16) and the upper run (21) rides on the lower run (23) when the belt (22) is operated. The flow of cryogenic fluid through the tunnel (12) is aided by vaporization of a cryogenic fluid and baffles (98), but no air-moving devices located within the tunnel (12).

摘要： A method for determining the flow rate of a fluid, having a liquid fraction and a gas fraction, having the steps of: measuring the pressure and temperature of the fluid at a flow control device through which said cyrogenic fluid passes; inputting the measured pressure and Cv into an algorithm; and performing a single or multi-step iteration to determine a fluid mass flow rate of the fluid through the flow control device using the algorithm that relates the mass flow rate of the fluid to the Cv, and mass densities of the liquid fraction and the gas fraction of the fluid which are a function of the measured pressure, and temperature. A system is also provided.

摘要： Method and apparatus for reclaiming sand from a foundry sand containing, inter alia, a clay binder by cooling the foundry sand to a temperature at or below -40.degree. C. (-40.degree. F.) followed by separation of the sand from the binder while the sand is maintained at a temperature at or below 0.degree. C. (32.degree. F.). Foundry sands with clay binders have a water content to 1% to 15% by weight prior to being cooled.
