he Okadora Carbonizer is a completely sealed structure, composed of a wrap-around jacket, in which hot air is supplied at 600 deg.C. Inside the shell, a specially designed fin is attached to the shaft and placed in the center of the shell. By rotating the fin, the loaded material is pushed against the heating wall of the jacket by centrifugal force, forming a thin film, which is kept at about 600 deg.C. by the hot air. Carbonizing is completed in 40~60 minutes. Even though the temperature during the process is 400 to 450 deg.C., poly-vinyl chlorides and the like can’t react with oxygen because the oxygen content is less than 1%. Chlorides of PVC and hydrogen are separated from benzene, transforming into gaseous vapors separately, and then being conducted to the deodorant apparatus. The channel to the deodorizer is also oxygen-free (no carbon monoxide) and thus no oxidization takes place. Under these conditions, separated gaseous vapors of chlorides and hydrogen are instantly burnt out in a chamber of the deodorizer at a temperature higher than 800 deg.C. As complete incineration takes place in the chamber, no carbon monoxide is produced, nor are there any burnt ashes to act as a catalyst for the formation of dioxins. Therefore no dioxin is produced.

Okadora Original Technology turns high-speed treatment into a reality and makes industrial waste treatment pollution-free.
