摘  要：
为了提高豆粕加工双螺杆挤出机的混合性能,采用ANSYS-CFX对带有开槽捏合块混炼元件的双螺杆挤出机流道进行三维流场分析,比较豆粨在开槽捏合块及普通捏合块挤出过程中的运动规律。包含速度场、压力场、加权平均剪切速率,以及挤出机流场的对比分析。结果表明:开槽捏合块元件相比于常规捏合块能够显著增强对豆粨的剪切速率,使剪切速率提高1.4倍,能够使轴向建压能力增强,在凹槽处形成背压区,增加豆粨在开槽处的运动时间,提高双螺杆挤出机的分散混合性能。

摘  要：
In order to improve the mixing performance of soybean meal processing twin-screw extruder, the three-dimensional flow field of the twin-screw extruder flow path with slotted kneading block mixing elements by ANSYS-CFX was analysised for studying the movement regulation of soybean meal during extrusion. Contains velocity field, pressure field, weighted average shear rate, and comparative analysis of the extruder flow field with conventional kneading blocks. The results showed that the slotted kneading block element significantly enhanced the shear rate of the soybean meal compared to the conventional kneading block, increased the shear rate by 1.4 times, enhanced the axial pressure building capacity, formed a back pressure zone at the groove, and the flow time of the soybean meal at the slotting was increased, and the dispersion mixing performance is improved.
