  • Acoustic thawing of frozen food
    Patent number: 4464401
    Abstract: The thawing time of frozen block fish is shortened by immersing the frozen block fish in a water bath at a maximum temperature of about 10.degree. C. and subjecting the frozen fish to a maximum of about 6 watts of acoustic power having a frequency equal to the relaxation frequency of the polycrystalline ice in the frozen fish and less than 10 kHz, thereby quickly thawing the ice without heating the thawed fish flesh.
