Abstract
An object of the invention is to provide a granulation method and a granulation apparatus that can reduce the manufacturing costs of pellets. There is provided a granulation method which uses an underwater cutting (UWC) devicethat cuts a medium to be processed extruded from holes of a dieby using cutter blades provided in a circulation boxand conveys the cut pellets from the circulation boxwhile cooling the cut pellets by pellet cooling/transport water (PCW). The granulation method includes circulating the PCW and stopping the circulation of the PCW after pushing the cutter blades against the diewhile rotating the cutter blades, before the start of the granulation; storing a predetermined amount of PCW in the circulation boxby discharging the PCW; and heating the PCW, which is stored in the circulation box, up to 69° C. or more.
