Abstract: A heating/stirring cooker includes a stirring body. The stirring body is detachably attached to the interior of a container, and stirs the food. The stirring body includes a blade, a permanent magnet, a magnetic metal plate, a storage, and a clutch. The blade stirs the food. When the stirring body is attached to the container, the permanent magnet is located opposite the inner bottom surface of the container and receives a rotating magnetic field. The magnetic metal plate is provided on the permanent magnet and inhibits magnetic flux leakage. The storage has a perimeter on which the blade is formed, and movably stores the permanent magnet. The clutch transmits the rotational force of the rotating magnetic field to the storage, only when a claw is in engagement with a notch. The stirring body generates high rotational force when attached and suppresses the impact of the magnetic field when detached.

The first power distributor distributes the generated power of the power generator to a power system and the heating unit. When the internal pressure of the accumulator tank reaches a predetermined pressure and the generated power is larger than the power demand, the controller supplies a part or all of the generated power to the heating unit by the first power distributor.

The absorber contacts the gas with the treatment liquid. The liquid separator separates the treatment liquid having been in contact with the gas into a first phase portion having a high content of the acidic compound and a second phase portion having a low content of the acidic compound. The regenerator heats the first phase portion to eliminate the acidic compound from the first phase portion. The circulation mechanism recycles the second phase portion and the treatment liquid from which the acidic compound has been eliminated by the regenerator, in the absorber as a treatment liquid with which the gas is to be contacted. The heat transfer apparatus transfers heat from the treatment liquid discharged by the absorber and from the gas having undergone separation of the acidic compound, to the treatment liquid in the regenerator.
