【摘要】 利用小型自热式单螺杆挤压膨化机对农作物秸秆进行膨化加工试验。将螺杆螺距、喷嘴出口间隙、秸秆物料含水率、秸秆物料粒度作为试验因素 ,经单因素试验和二次通用旋转组合设计试验找出其对秸秆膨化加工性能(膨化压力、生产率、度电产量等)的影响规律 ,并得出最佳参数组合更多还原

【Abstract】 A small-size single-screw extruder with self-heat was tested. Screw pitch, spray nozzle clearance, chopped straw moisture content and straw size were different factors. Influences of processing property (extruding pressure, production efficiency, output per degree) was abstained by a series of single factor and general rotatory regression design for second power experiment. The optimal combination of main parameters was gained by optimization design method.更多还原
