Abstract: Embodiments of the present invention disclose methods for producing pre-conditioned solutes that exhibit no temperature spike during super-cooling in a cryogenic process. In addition, the solutes demonstrate utile capabilities and characteristics such as more efficient heat absorption rates and eutectic material properties which make the pre-conditioned solutes an efficient heat exchange medium. The methods involve super-cooling a solute to induce a long-duration phase change capability. The pre-conditioned solute may be thawed and will retain long-duration phase change capabilities for subsequent freezing cycles if the freezing protocols disclosed herein are followed. Material to be frozen may be directly immersed into pre-conditioned, super-cooled solutes for freezing. The solute may be propylene glycol, glycerol, or other suitable solutes.

Abstract: This invention relates to a novel carbon dioxide product comprising a pumpable slurry consisting of finely divided particles of solid phase carbon dioxide dispersed in liquid phase carbon dioxide in which the solid particles are free flowing, i.e. do not agglomerate on standing for periods of time sufficient to permit beneficial commercial use of the product. The slurry is produced by withdrawing gaseous carbon dioxide at a controlled rate from a vessel containing liquid carbon dioxide at the temperature and pressure conditions of the triple point while vigorously agitating the liquid, to produce solid carbon dioxide particles in the liquid. The rate of formation of the solid is controlled to produce small, finely divided particles of solid carbon dioxide rather than large pieces.

Abstract: Methods for providing an expendable refrigerant which is emitted from a snow horn at a low velocity thereby enabling snow agglomeration at a close proximity to the horn exit and accurately delivering a charge of snow with minimum vapor loss. The desired snow is produced by introduction of the relatively warm liquid refrigerant into an insulated compartment and in heat exchange relation with a tube therein having a plurality of length/diameter ratios. The liquid refrigerant is effective to warm the tube walls and results in a slight cooling of such liquid which is then passed to a sub-cooler and returned to the tube inlet for expansion in several stages therein to form the snow. The product snow is emitted from this horn at a relatively low velocity and may be accurately directed into cavities of such products as eviscerated fowl.
