To provide a twin-screw kneading extruder and a vent adapter capable of suppressing vent-up.SOLUTION: A twin-screw kneading extruder includes: a first screw that rotates about a first rotation axis extending in a first direction in a horizontal plane; a second screw that rotates about a second rotation axis extending in the first direction at a position adjacent to a second direction orthogonal to the first direction in the horizontal plane with respect to the first screw; a tubular cylinder extending in the first direction for accommodating the first screw and the second screw; a drive unit arranged on one end side of the cylinder to rotate the first screw and the second screw; a die arranged on an other end side of the cylinder and ejecting raw material extruded by rotation of the first screw and the second screw as strand; and a vent adapter fitted to a top of the cylinder at a predetermined position in the first direction.SELECTED DRAWING: Figure 5 【課題】ベントアップを抑制することができる二軸混練押出機及びベントアダプターを提供することができる。【解決手段】一実施の形態にかかる二軸混練押出機は、水平面内における第１方向に延びた第１回転軸を中心に回転する第１スクリュ、及び、前記第１スクリュに対して前記水平面内における第１方向に直交する第２方向に隣接した位置で前記第１方向に延びた第２回転軸を中心に回転する第２スクリュと、前記第１スクリュ及び前記第２スクリュを収容する前記第１方向に延びた筒状のシリンダと、前記シリンダの一端側に配置され、前記第１スクリュ及び前記第２スクリュを回転させる駆動部と、前記シリンダの他端側に配置され、前記第１スクリュ及び前記第２スクリュの回転により押し出された原料をストランドとして吐出するダイスと、前記シリンダの前記第１方向における所定の位置の上部に嵌め込まれたベントアダプターと、を備える。【選択図】図５
