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.

A thawing method for a heating apparatus, and the heating apparatus. The heating apparatus includes a cavity capacitor used for placement of an object to be treated, and an electromagnetic wave generation module that generates an electromagnetic wave signal used for heating the object to be treated. The thawing method includes: receiving a thawing instruction input by a user, acquiring a feature parameter that reflects the weight of the object to be treated, a power value of the electromagnetic wave signal, and a rate of change in a dielectric coefficient of the object to be treated; and determining the thawing progress of the object to be treated according to the feature parameter, the power value and the rate of change. The present invention is less influenced by the precision of a sensing device itself, and achieves relatively accurate determination of the thawing progress.

A method for producing a reheatable food product includes mixing butter, maltodextrin and breadcrumbs so as to form a butter mixture, obtaining a first slice of bread and a second slice of bread, spreading the butter mixture onto a first surface of the first slice of bread and a first surface of the second slice of bread, applying 5 g to 70 g of a filling to the second surface of the first slice of bread, positioning the second slice of bread on the filling such that the second surface of the second slice of bread is adjacent thereto to form the food product, grilling the food product until the first surfaces are golden brown, and compressing the food product to a thickness of 0.56 inches to 0.75 inches while grilling, freezing the food product to a frozen state, reheating the food product.
