DRYING DEVICE AND DRYING METHOD

WIPO Patent Application WO/2013/039005

A1

The purpose of the present invention is to provide a drying device that uses atmospheric superheated steam to more efficiently dry a material to be dried. The drying device is provided with the following: an electromagnetic induction heater (1) to which a gas mixture of steam and dry air is provided through a conduit (L3) where a conduit (L1) to which atmospheric steam is supplied and a conduit (L2) to which atmospheric dry air is supplied merge; a control device (3) for controlling the electromagnetic induction heater (1) so as to heat the gas mixture and generate atmospheric superheated steam that becomes transparent at approximately 200°C or above; a conduit (L4) for connecting the electromagnetic induction heater (1) and a drying chamber (2); and the control device (3) for controlling the humidity to be at or below a prescribed humidity by adjusting the amount of atmospheric heated dry air supplied to the drying chamber (2). The temperature of the atmospheric superheated steam is lowered to a temperature that is both less than the boiling point of the solvent and high enough to be in a range where there is no reduction in the binding strength between a collector and an active material, the steam is supplied to the drying chamber (2) through the conduit (L4), and the humidity inside the drying chamber (2) is controlled.
