Abstract:
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.
