NOVELTY - The method involves heating the biomass fine granule filled at bottom of container to obtain solid substance before half carbonization. A pressurization element is inserted from upper portion of container for pressurizing the biomass fine granule in pressure range. A heating unit is provided in container for heating biomass fine granule. A molded object generated in container is switched from heating unit to cooling unit. The pressure of pressurization element is reduced and the bottom portion of container is released to perform extrusion discharge of molded object.    USE - Method of manufacturing bio-coke used as fuel in combustion installations such as boiler for electric power generation, and as heat source, reducing agent, etc., in cupola furnace, blast furnace, etc., for casting and iron manufacturing.    ADVANTAGE - Since the heating or cooling of biomass fine granule can be performed rapidly and smoothly using the cooling-heat intermediate flow path, the shortening of cooling time and discharge time of molded object can be achieved and the productivity is improved. The hydraulic mechanism and cooling-heat intermediate circulation mechanism are controlled using control apparatus, so that the bio-coke can be manufactured efficiently.    DETAILED DESCRIPTION - The position of pressurization element in reaction container is detected at the time of discharge of molded object. The clogging of molded object is judged and the molded object is switched from cooling unit to heating unit, when the pressurization element is not arrived at lowest end. A cooling-heat intermediate flow path is formed in outer peripheral of reaction container for passing heat medium or refrigerant to heat or cool the biomass fine granule. The heat medium is passed through the intermediate flow path, when the clogging of molded object is judged. An INDEPENDENT CLAIM is included for bio-coke manufacturing apparatus, which includes a control apparatus for performing pressure control of pressurization element, switching control of heating unit and cooling unit and the opening/closing control of bottom portion of reaction container.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the molded object discharge process. (Drawing includes non-English language text)
