A micro-vibration wave generating device includes: a power indicator circuit, a first transformer micro-vibration wave generating circuit, and a receptor. An input end of the power indicator circuit is connected to the power source; an input end of the first transformer micro-vibration wave generating circuit is connected with an output end of the power indicator circuit; the receptor is connected with an output end of the first transformer micro-vibration wave generating circuit. Micro-vibration waves generated by the transformer micro-vibration wave generating circuit can resonate with the waterolecules in the food, and thereby the water molecules form soft and non-spiky crystals of water molecules when they are frozen, which greatly reduces the damage to the food cells. Accordingly, the quality of the food is intact without mixing odors. The present invention can also be used in cooking deep fried food with almost no oil smoke produced.

A method of thawing an object (21) in a frozen state placed in an interior of a container (10), in which an AC voltage which is 10V or higher and 5 kV or lower is applied to the object (21) in the frozen state to flow a current which is 1 μA or higher and 1000 mA or lower, through the object (21) in the frozen state, includes the steps of: partially thawing the object (21) in the frozen state in such a manner that a temperature in the interior of the container (10) is controlled to cause the object (21) in the frozen state to be partially thawed while applying the AC voltage to the object (21) in the frozen state; and stopping application of the AC voltage to the object (21) and preserving the object (21) while maintaining a state in which the object (21) partially thawed.
