NOVELTY - The method involves pressurizing biomass fine granules filled in a reaction container by low pressure using a pressurizing unit. The biomass fine granules are heated by a heating unit in predetermined temperature range for predetermined time, while increasing the pressure of the pressurizing unit. The molded object is cooled by a cooling unit. The bottom portion of the reaction container is opened and the cooled molded object is discharged, after reducing the pressure of the pressurizing unit.    USE - Manufacturing method of bio-coke used as alternative fuel for coal coke. Uses include but are limited to fuel for boiler, fuel for baking application, electric power generation application, used as heat source and reducing agent in cupola furnace and blast furnace used in casting production and iron manufacture, etc.    ADVANTAGE - The bio-coke can be manufactured efficiently in short period of time by cooperating the pressurizing unit, heating unit and cooling unit. Since the biomass fine granules are pressurized at the time of filling the biomass fine granules in the reaction container, the amount of biomass fine granules thrown into the reaction container can be increased, while reducing the size of the reaction container. The bio-coke of fixed size can be obtained by setting the pressure value and filling amount in predetermined ranges. The filling amount of biomass fine granules can be estimated easily. The process of switching from the heating operation to cooling operation can be performed smoothly. The molded object can be easily discharged by opening the bottom portion of the reaction container.    DETAILED DESCRIPTION - The bottomed cylindrical reaction container is filled with the biomass fine granules and the biomass fine granules are pressurized using the pressurizing unit by dropping the pressurizing unit from the upper side of the reaction container. The biomass fine granules are heated while pressurizing to obtain solid substance in dense state before half carbonization. The pressure value of the pressurizing unit and the filling amount of the biomass fine granules in the reaction container are detected at the time of pressurization and at the time of filling so that the pressure value and filling amount is maintained in respective preset ranges. The filling amount of the biomass fine granules is detected using the position sensing device which obtains the upper end position of the biomass fine granules in the reaction container. The number of times the pressurizing unit is descended is counted using the counter during the filling process. The abnormality of pressurization at the time of filling is determined, when the number of times the pressurizing unit is descended is less than the number estimated during normal state. The heating and cooling operations of the biomass fine granules are performed by supplying heat medium or coolant to the outer periphery of the reaction container. The heat medium is circulated initially for predetermined time and then coolant is circulated with respect to the outer periphery of the reaction container during reaction process. An INDEPENDENT CLAIM is included for bio-coke manufacturing apparatus having a control apparatus that performs pressure control of the pressurizing unit and switching control of heating unit and cooling unit. A pressure sensing device detects the pressure value of the pressurizing unit. A filling amount detection unit detects the filling amount of the biomass fine granule in the reaction container. The control apparatus controls the pressurizing unit to repeatedly perform pressurization at the time of filling the biomass granule in the reaction container, so that pressure value and filling amount corresponds to the preset range. The control apparatus detects abnormality based on the number of times the pressurizing unit is descended with respect to the reaction container.
