Abstract: It is an object of the invention to provide a cooking device and a cooking method which can quickly discharge a steam supplied into a heating chamber from the heating chamber and can cook an object to be heated through uniform steam heating by setting the steam in the heating chamber to have a suitable temperature for the cooking. A cooking device (100) for supplying a steam S to a heating chamber (11) accommodating an object M to be heated, thereby heating the object M to be heated includes steam supplying means for supplying the steam (S) to the heating chamber (11), and air discharging means for discharging the steam supplied to the heating chamber (11) from the heating chamber (11).

Abstract: The problem to be solved by the invention is that, when an object to be heated is heated using steam, the atmospheric temperature of the interior of the heating chamber is set quickly and accurately at a temperature suitable for cooking to thereby cook the object to be heated with uniform steam heating. The above problem can be solved by providing a cooking apparatus for supplying steam to a heating chamber 11 storing an object to be heated to thereby heat the object to be heated, which comprises steam supply means for supplying steam to the heating chamber 11, a fan 17 for stirring up the steam supplied to the interior of the heating chamber 11, and temperature control means, by driving and rotating the fan 17, for controlling the atmospheric temperature of the interior of the heating chamber 11 to be lower than the temperature of the steam supplied.

Abstract: To provide a thawing method wherein a frozen commodity can be thawed, in a short time, from the inside with no unevenness. The thawing method, which thaws a frozen commodity by high frequency heating, includes: a first high frequency heating step in which the frozen commodity is high frequency heated to the vicinity of a melting temperature; a temperature detection step which measures the temperature of the frozen commodity during the first high frequency heating step and detects that the measured temperature has reached the melting temperature; a steam supplying step which starts a steam supply when the melting temperature is detected in the temperature detection step, thus forming a film of dew condensation on the surface of the frozen commodity; and a second high frequency heating step in which the frozen commodity is high frequency heated after the start of the steam supplying step.
