FREEZING METHOD

A method of inducing nucleation of freezing in a material within a chamber is provided. The material to be frozen is initially brought to a temperature near or below a phase transition temperature in an atmosphere within the chamber pressurized above ambient pressure after which the pressure of the...

Zusammenfassung:A method of inducing nucleation of freezing in a material within a chamber is provided. The material to be frozen is initially brought to a temperature near or below a phase transition temperature in an atmosphere within the chamber pressurized above ambient pressure after which the pressure of the atmosphere within the chamber proximate the material is decreased in 40 seconds or less or at a pressure rate drop, delta P / delta t, greater than about 0.2 psi (1,38 kPa) per second to uniformly induce nucleation of the phase transition in the material.
