To improve kneading efficiency.SOLUTION: A kneader comprises: a kneading pot 11 extending in a horizontal direction; a plurality of kneading rods 12 arranged in an annular shape on two different concentric circles, with a central axis of the kneading pot 11 being a rotational central axis; and a power unit for making the kneading rod 12 to perform intermittent kneading processing operation, which repeats low speed rotation and rotation at higher speed than the low speed rotation, when rotating the kneading rod 12 around the rotational central axis. Among the kneading rods 12 arranged in an annular shape on the concentric circles, an outer kneading rod 12b positioned on an outer side and an inner kneading rod 12a positioned on an inner side are arranged with different angle offsets relative to the rotational central axis. The inner kneading rod 12a is positioned with a prescribed clearance with respect to the outer kneading rod 12b positioned on an upper side in a rotational direction.SELECTED DRAWING: Figure 3 【課題】混練効率を向上させること。【解決手段】水平方向に延在する混練釜１１と、混練釜１１の中心軸を回転中心軸として２つの異なる同心円上に環状に配置された複数の混練棒１２と、回転中心軸を中心として混練棒１２を回転させる際に、混練棒１２に、低速回転と、低速回転より高速である回転と、を繰り返す間欠混練処理動作を実施させる動力部と、を備え、同心円上に環状に配置された混練棒１２のうち、外側に配置された外側混練棒１２ｂと、内側に配置された内側混練棒１２ａの配置は、回転中心軸に対して異なる角度オフセットで配置されているとともに、内側混練棒１２ａは、回転方向上方側に配置された外側混練棒１２ｂに対して所定のクリアランスを持って配置されている。【選択図】図３
