摘　　要：本试验采用SDP-45小型单螺杆挤压膨化机,通过三因子五水平二次通用旋转组合设计,研究了豆粕挤压膨化系统诸参数(物料含水率、螺杆转速、机筒温度)对产品容重的影响规律,并优化了挤压膨化系统的最佳参数。结果表明,影响产品容重的豆粕挤压膨化系统诸因素主次排序为:机筒温度>物料含水率>螺杆转速。其较优组合为螺杆转速为240r/min、机筒温度为130℃、物料含水率为28%。The trail studied the influence of parameters of soybean extrusion system （moisture of material ,speed of screw,barrel temperature）on the product bulk density using a small single-type extruder and optimized the parameters of extrusion system by current rotation combination design of three factors and five levels.The results showed that the sequence of factor affecting productivity was barrel temperature 〉 moisture of material 〉 speed of screw.The optimized combination of factors were speed of screw 240 r/min, barrel temperature 130 ℃ and moisture of material 28 %.
