Further, in the present embodiment, the carbonization fluid heating tube 230 that heats in response to a voltage application is used, and the intermediate portion of the carbonization fluid heating tube 230 provided with one or more carbonization discharge ports. Since the 233 is arranged so as to face the carbonization upper opening 215 of the carbonization case 210, the carbonization upper opening 215 and the intermediate portion 233 are hermetically covered by the carbonization cover case 240. In addition to being able to efficiently supply high-temperature superheated steam to the entire carbonization space 210A, the temperature inside the carbonization space 210A can be raised not only by the amount of heat generated by the superheated steam but also by the amount of heat of the carbonization fluid heating tube 230.
