Abstract
A thawing method for a thawing device includes: generating, by a radio frequency generation module, a radio frequency signal in a frequency range of 40 to 42 MHz; obtaining the radio frequency signal; and generating, by an upper electrode plate and a lower electrode plate, radio frequency waves of corresponding frequency in a thawing chamber according to the radio frequency signal, and thawing an object to be processed in the thawing chamber. Radio frequency waves using the above frequency range have shorter thawing time, higher temperature-uniformity and lower juice loss rate than radio frequency waves of other frequencies.
