MULTIPURPOSE THAWING MACHINE IN WATER AND IN AIR BY LOW-TEMPERATURE LIQUEFIED GAS

摘要

PROBLEM TO BE SOLVED: To provide thawing machines and the related functional commodity with faithfully reproducible functions of good freshness at bearable prices in the range of machines for food supermarkets, restaurants and small machines for ordinary families.;SOLUTION: By the slight consumption of low-temperature oxygen-free liquefied gas 1, which, for example, is -196°C liquid nitrogen gas in the thawing machine in the water, and by the underwater diffusion of the slight amount of the gas, the explosion ultrasonic wave and the cavitation energy emanation of the underwater bubble 11 of the oxygen-free gas, from which a 200°C temperature difference is brought, are utilized. In the thawing machine in the air, the exchange of oxygen-containing air in the treatment tank 5 for liquid nitrogen gas, with the cyclic use of the oxygen-free gas and the wind pressure of the humidification gas in the tank, both in the water and in the air treatments, makes it possible to perform rapid thawing with no-oxygen, no-drying, no-dripping, keeping the fresh color of flesh, and retaining freshness. An expensive electric ultrasonic wave oscillator, a catalyst compression diffusion chilling unit and the like are not needed, and the treatment tank 5, the underwater treatment pump 13 and, in the case of the treatment in the air, a fan, moreover, the liquefied gas pipe unit and the oxygen-free gas 3 are only needed.;COPYRIGHT: (C)2011,JPO&INPIT
