Abstract: In order to ensure quality of pellets by eliminating temperature differences among extrusion nozzle holes with use of a heating medium flowing through heating channels only once and flowing out through a heating medium outlet, provided is a die plate for resin granulation, in which a plate main body (1) is divided into regions (A to n) for every 360/n (n=4, 6, or 8) degrees, or into first to fourth regions (A to D) for every 90 degrees, and an inner annular heating passage (4) and an outer annular heating passage (5) are formed. A heating medium (F) supplied through a heating medium inlet (2) flows through heating channels (8) only once, and then flows out through a heating medium outlet (3) to an outside.
