摘  要:
Utilizing the transmission property of ultrasound in frozen food, it is possible to unfrozen food quickly. In this paper ultrasound thawing of beef was studied theoretically. The effects of frequency, intensity and loading direction of ultrasound on the possible depth that could be thawed without excess temperature were analyzed. The unfrozen experiments were carried out with ultrasound of 800 kHz, and the obtained results were in consistent with the numerical calculation. The feasibility of ultrasound thawing of frozen food was verified.
