In addition, since the configuration of the mixing device 20 is simple and the structure is simple, installation cost is low and installation space is occupied.

The drying device 30 dries the mixture so that the moisture in the mixture is at an appropriate level for molding into a heat stick or green stick.

Referring to Figure 4, the drying device 30 is a pair of drying furnaces (31a, 31b), transfer blades (32a, 32b), a heater (33), a hot air outlet (34), opening and closing pressure control unit (35) Includes.

The opening and closing block 352 is rotatably coupled to the shaft of the screw 351 by a bearing, so that the shaft of the screw 351 can be used as the guide rod 353.

The mixture supplied from the mixing device 20 to the inlet of the drying device 30 through the transfer conveyor 26 is transferred toward the drying furnaces 31a and 31b, and is blocked by the opening and closing block 352 and is accumulated at the inlet. When the pressure applied by the mixture accumulated at the inlet exceeds the pressure of the pressure spring 356, the opening/closing block 352 moves backward and opens the inlet, so that the mixture compressed and accumulated in the inlet is put into the drying furnaces 31a and 31b. . By adjusting the rotational speed and rotation timing of the screw 351, the amount of the mixture added to the drying furnaces 31a and 31b can be adjusted.

At the inlet, the mixture is piled up in a compressed state, closing the inlet. Thus, by keeping the inside of the drying furnaces 31a and 31b sealed, the pressure, temperature, humidity, and the like in the drying furnaces 31a and 31b can be controlled.
