<P>PROBLEM TO BE SOLVED: To provide an induction heating device free from unevenness in heating or drying in the axial direction and diametrical direction of a heated object, even if an axial length of a cylindrical heated object is longer than its diameter. <P>SOLUTION: The heated object sandwiched by electrodes to which high frequencies are applied is rotated on a long axis to make a temperature in the peripheral direction and a water content uniform, the temperature and the water content of the heated object near the electrodes are arbitrarily controlled by dividing the electrodes to the axial direction and changing positions from the heated object of the electrodes, furthermore auxiliary electrode plates are disposed in a state of being supported by a hinge structure, and an opening angle of the auxiliary electrode plates is changed to perform uniform heating and drying also in the cross-sectional direction of the heated object. <P>COPYRIGHT: (C)2010,JPO&INPIT |
