Abstract
【解決手段】処理室2に互いに平行に配された2本の回転軸4に、その軸方向に沿って複数の正三角形状の撹拌翼3を一定方向に一定量だけ偏心させた状態で固定し、各回転軸4を同一方向に同一回転速度で回転させたときに、各回転軸4のそれぞれに軸方向の同一位置で固定された2つ一組の撹拌翼3が、その一方の撹拌翼3の一つの頂点が他方の撹拌翼3の輪郭に近接する状態を維持しながら偏心回転し、互いの外周に付着した重縮合系樹脂(被処理物)を掻き取るとともに、処理室2の内壁に近接する頂点でその内壁に付着した樹脂を掻き取るようにすることにより、従来の円板状の撹拌翼を用いたものよりもセルフクリーニング性能に優れたものとなり、安定して長時間運転できるようにしたのである。
