The carbonizing fluid heating pipe 230 is heated when a voltage is applied to the first and second feeding points 235 and 236 to convert the steam in the internal space or the mist-like water into superheated steam.
The superheated steam generated by the carbonization fluid heating pipe 230 is discharged to the outside from one or a plurality of discharge ports (not shown) provided in the intermediate portion 233, and carbonized through the carbonization upper opening 215. It is supplied to the space 210A.

By fixing to the upper surface 211 of the case 210, the intermediate portion 233 of the carbonizing fluid heating pipe 230 faces the upper opening 215 for carbonization.

  In the present embodiment, as described above, the carbonization heating steam generation mechanism is configured to generate superheated steam by the heat generation action of the carbonization fluid heating pipe 230 in response to voltage application. The invention is not limited to such a form.

  That is, the drying superheated steam generating mechanism heats the steam or mist-like water supplied from the water supply unit 90 by electromagnetic induction to generate superheated steam (not shown) for carbonization. A carbonization fluid pipe (not shown) to which superheated steam generated by the carbonization electromagnetic induction heating means is supplied, and a carbonization cover case 240 capable of closing the carbonization upper opening 215 in an airtight state. You may have.

  In the present embodiment, for example, the control unit 300 controls the drying fluid heating from the power source so that the heating temperatures of the drying fluid heating tube 130 and the carbonizing fluid heating tube 230 become the set temperatures. A voltage application time to each of the tube 130 and the carbonizing fluid heating tube 230 is controlled.

  As an example, the surface temperature of the drying fluid heating tube 130 is set to a first temperature (for example, about 400 ° C.), and the carbonizing fluid heating tube 230 has a second temperature whose surface temperature is higher than the first temperature. (For example, 850 to 1100 ° C.).

Further, the conveying speed of the carbonized screw conveyor 120 is set to be higher than the conveying speed of the drying screw conveyor 220.

Since 133 is arranged so as to face the upper drying opening 115 of the drying case 110, the upper drying opening 115 and the intermediate portion 133 are hermetically covered by the drying cover case 140. In addition to being able to efficiently supply high-temperature superheated steam to the entire drying space 110A, the temperature in the drying space 110A can be raised by the heat quantity of the drying fluid heating pipe 130 together with the heat quantity of the superheated steam, Good heating efficiency can be obtained.

  Further, in the present embodiment, while the workpiece processed by the drying unit 100 is conveyed from one side of the carbonization space 210A defined by the carbonization case 210 to the other side by the carbonization screw conveyor 220, Since the superheated steam generated by the carbonized superheated steam generation mechanism is supplied to the object to be processed through the carbonization upper opening 215 of the carbonization case 210, the carbonized space 210A High-temperature superheated steam can be efficiently supplied to the whole.

  Further, in the present embodiment, the intermediate portion of the carbonization fluid heating tube 230 provided with the one or a plurality of carbonization discharge ports using the carbonization fluid heating tube 230 that heats in response to voltage application. Since the carbonization upper opening 215 and the intermediate portion 233 are hermetically covered by the carbonization cover case 240 while the carbonization case 210 is disposed so as to face the carbonization upper opening 215 of the carbonization case 210.
