NOVELTY - The method involves drying moisture content in fibrous biomass consisting of empty fruit bunch generated in palm-oil production to 10 mass % or less, and controlling particle-size of fibrous biomass to length of 0.5-10 mm. The dried and particle-size controlled fibrous biomass is passed through openings formed in screen. The supply of fibrous biomass through raw material supply port at raw material storage portion is performed. The hollow cylindrical molding obtained by providing frictional resistance while pushing fibrous biomass towards cavity and heating is dry-distilled.    USE - Manufacturing method of carbide used in waste material melting furnace (claimed) such as waste material gasified melting furnace of shaft type.    ADVANTAGE - The bridging of fibrous biomass within the apparatus can be prevented, so that the carbide can be manufactured in low cost without passing through the manufacturing process of granulated material. Since fibrous biomass entraps continuously to the groove between screw blades, in a state without stirring and performing push operation in raw material storage portion, the fibrous biomass after crushing or grinding can be supplied to the heating-pressing molding portion, and supply-amount can be equalized. Since supply-amount to heating-pressing molding portion can be equalized, the formation of hollow cylindrical molding with non-uniform density based on the dispersion in supply-amount can be suppressed. By the fine adjustment of the density of hollow cylindrical molding, the maintainability, eccentric correction and cleaning of screw front-end can be improved.    DETAILED DESCRIPTION - The fibrous biomass is heated to the temperature of 150-250 degrees C. The dry distillation is performed at the temperature 600-1200 degrees C. The frictional resistance is provided by moving fibrous biomass in the inner side of cavity portion in the state which arranged the fibrous biomass in the outer peripheral surface of the resistance portion, and the cavity portion of the dies. A heating area for heating the fibrous biomass pushed in by the second screw is formed in the cavity portion. The front-end of resistance portion is extended even in the range of 1/5 - 4/5 of heating area. The resistance portion is provided at the front-end of the screw so that removal is possible. An INDEPENDENT CLAIM is included for a manufacturing system of the carbide has raw material storage portion that stores the fibrous biomass by which fall supply is performed from the raw material supply port formed in the upper surface. Heater for heating dies provided with the cavity portion. Carbonization apparatus dry-distills the hollow cylindrical molding. The blade pace of normal line direction with respect to blade surface of screws is 10 times or more of the largest length of screen opening portion. The minimum separation distance of the blade tip of first screw and the side wall of the raw material storage portion is 5 times or less of the largest length of the screen opening portion.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the manufacturing process of the carbide. (Drawing includes non-English language text)
