In order to equalize the drying of the treated material, the treated material of the waste is thrown into the space, stirred evenly, and fed into the conical portion 2 for carbonization that is connected to the cylindrical portion 1 for carbonization. A drying process is adopted which employs a method of increasing the carbonization efficiency by continuously contacting the treated products to equalize the drying.
