Abstract
The present invention discloses a method for modulating freezing of a liquid substance, said liquid substance being in the presence of a gas phase, the method comprising modulating the temperature of the liquid substance, of the gas phase or of both, and controlling the concentration of vapor of the substance present in the gas phase. The invention further comprises a method for preservation, for example, food or other biological material, and an apparatus for putting said method into practice.
Claims17
A method for modulating freezing of a liquid substance, said liquid substance being in the presence of a gas phase, the method comprising modulating the temperature of the liquid substance, of the vapor phase or of both, and controlling the concentration of vapor of said substance present in the gas phase.
The method according to any of the previous claims, wherein the ratio between temperature and concentration of vapor of the substance in the gas phase is kept within a pre-determined relationship thereby preventing freezing of the liquid substance.
The method according to any of the previous claims wherein said liquid substance is water.
The method of any of the previous claims for modulating freezing of a liquid substance in a material that comprises said liquid.
An apparatus for modulating freezing of a liquid substance, said liquid being in the presence of a gas phase, the apparatus comprising a chamber adapted to receive said liquid substance, means for controlling the temperature of the liquid or of a material containing said liquid, of the gas phase or of both, and which is capable of bringing the temperature below the nominal freezing point of the liquid, and means for controlling the concentration of the substance present in the gas phase.
Use of means to control the concentration of vapor of a substance in a gas phase to modulate freezing of a supercooled liquid of said substance, said liquid substance being in contact with the gas phase.
