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 preconditioned 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.
