摘要:
单螺杆挤出机是加工以豆粕为原料的膨化食品行业中使用的关键设备。普通单螺杆挤出机存在混合不充分、比能耗低的缺点，为了提高其性能，运用ANSYS/CFX软件对具有三角屏障混炼元件以及反向螺纹元件的新型单螺杆挤出机的流道进行流场分析。研究分析豆粕在其流道中的运动情况，包括速度矢量图、速度流线图、宏观压力图，并和具有普通单螺杆元件挤出机进行对比分析，结果表明：新型组合式单螺杆挤出机的建压能力较好，可切断重排豆粕的速度流线，有利于豆粕更好地混合。研究结果可为单螺杆挤出机设计提供参考。
Abstract:
Single screw extruder is the most widely used tools for the production of expanded food with soybean meal as raw material In order to improve the production performance, this paper using ANSYS/CFX software to analyze material flow field of single screw extruder which with a triangle groove barrier mixers and counter screw, study and analyze the movement of soybean meal in its channel Including the velocity vector，velocity flow charts，macroscopic pressure field And then these were compared with ordinary screw Results indicate that the new type screw of single screw extruder has better ability to build pressure, cut off and refresh the velocity vector, it benefits for materials mixing The research can provide references for designing the single screw extruder
