To provide a plastic pellet diffusion device and a diffusion method possible to be used to diffuse plastic pellets evenly in a lateral direction.SOLUTION: There is provided a plastic pellet diffusion device 10, including: a pipe 1 for draining plastic pellets downward; an inclined plate 3 having a pair of plates 2 having a top side 3t disposed below the pipe and extending downward from the top side 3t to both ends; and a diffusion bar 4 disposed on an extension of each plate 2 in an inclination direction and extending in a direction parallel to the top side 3t. A cross-sectional area A of the pipe 1 is 20 to 300 cm. A sum B of lengths in the inclination direction of the respective plates 2, an inclination angle θ, a distance C between a lower edge of the inclined plate and the diffusion bar, and a cross-sectional area E of the diffusion bar are in a specific relationship.SELECTED DRAWING: Figure 2 【課題】プラスチックペレットを横方向に均等に拡散させる場合に用いることができるプラスチックペレット拡散装置及び拡散方法を提供する。【解決手段】プラスチックペレットを下方に流出させる配管１と、頂辺３ｔが該配管の下方に配置され、該頂辺３ｔから両端に向って下り勾配にて延在する１対の板体２を有した傾斜板３と、各板体２の傾斜方向の延長線上にそれぞれ配置され、前記頂辺３ｔと平行方向に延在する拡散バー４とを備えたプラスチックペレット拡散装置１０。配管１の断面積Ａが２０〜３００ｃｍ２であり、各板体２の傾斜方向の長さの和をＢ、傾斜角度をθ、傾斜板の下縁と拡散バーとの距離Ｃ、拡散バーの断面積Ｅが特定の関係にある。【選択図】図２
