Continuous carbonization apparatus and method

The present invention provides one kind one continuous carbonizing method and apparatus. The method can treat great amount of matter without generating offensive odor, and has raised carbonizing efficiency, reduced fuel consumption and lowered cost. The continuous carbonizing apparatus includes long horizontal tunnel kiln comprising preparing zone, pre-heating zone, carbonizing zone, cooling zone and conveying zone successively; and re-burning deodorizing furnace performing heat treatment to gas exhausted from the tunnel kiln. The full carbonizing process from loading the matter to be carbonized into the storing boxes to discharging the carbonized matter is completed in the tunnel kiln.
