Abstract

PROBLEM TO BE SOLVED: To carry out thawing by a third cold mist except thawing by heat or water flow by contacting steam and cold mist generated by a specific method from water having a specific temperature to materials to be cooled in a cold mist generating chamber unit. SOLUTION: When water having 12-18 deg.C temperature is showered by using a nozzle in a cold mist generating chamber unit (b), showered water takes the latent heat of vaporization from surrounding air, circulating water, etc., in the cold mist generating chamber unit (b) to generate steam having 100% humidity. Subsequently, a good heating medium is obtained by generating cold mist having 7-12 deg.C temperature together with the obtained steam having 7-12 deg.C temperature and 100% humidity. Temperature of air in the cold mist generating chamber unit and circulating water taken the latent heat of vaporization drop to 7-12 deg.C. The cold mist type thawing is carried out by contacting the 7-12 deg.C steam having 100% relative humidity to the material to be cooled.
