<p><P>PROBLEM TO BE SOLVED: To provide a new continuous reduced-pressure drying/carbonizing apparatus capable of continuously and efficiently carrying out the drying/carbonizing treatment by one apparatus to provide a high-quality carbonized product when drying and further optionally carbonizing a liquid-containing (organic) waste. <P>SOLUTION: The continuous reduced-pressure drying/carbonizing apparatus has a drying/carbonizing chamber 14 and a heating furnace 12. A pressure-reducing device 20 such as an ejector, reducing the pressure in the drying/carbonizing chamber 14 and sucking and discharging the generated steam is connected to the drying/carbonizing chamber 14. The drying/carbonizing chamber 14 is formed out of mutually communicated and connected two or more screw kneaders 24, 24A and 24B the main bodies of which are arranged in the heating furnace 12. The raw material conveyed from a raw material-feeder 16 is regulated so as to be fed to the drying/carbonizing chamber 14 from the lower part so as to carry out self-sealing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
