NOVELTY - A carbonization unit (4) has a gas inlet and a gas suction opening at the upper and lower sections, respectively. A gas circulation line (C) is provided between the gas inlet and suction opening, with a combustion hot blast generator (10) arranged at its intermediate portion. When heating gas is supplied through the gas inlet, deoxidization and heating of a target object (5) are performed in the generator.    USE - Used for performing the continuous carbonization of waste material such as human organic waste, solid cellulose waste, sewage-disposal sludge, buck wheat husk, waste material from foodstuff manufacture industry and pulp lees from paper industry.    ADVANTAGE - The process enables the continuous carbonization of waste material smoothly and efficiently, without requiring the monitoring arrangement, by providing combustion hot blast generator at the middle of gas circulation line. The process enables the pulverization of different types of target objects conveniently and enables the removal of carbonized material at the downstream side, reliably.    DETAILED DESCRIPTION - A gas circulation line is provided between the gas inlet and gas suction opening, exterior to the carbonization furnace (1). A carbonized material feedback line (B) is provided between the carbonized material extraction opening (3) and target object supply port (2). A target object supply line (A) connecting the heating pulverization mixer (19), carbonized material kneaders (20a, 20b) and a drier (21) is provided at the target object supply port. The pulverization mixer is arranged at the upstream side of the horizontal casing (31) having spiral shaped-pulverization nail (33).
