摘要
通过实验研究了双螺杆食品挤压机的机筒温度、供料速度、螺杆转速对产品质量（以比容衡量）的影响规律，建立了相应的统计模型，并对操作参数进行了优化。研究表明，随着机筒温度的升高，比容呈增大趋势，螺杆转速与供料速度对比容的影响较复杂，与比容之间的关系呈非线性。当机筒温度在160～166℃之间，螺杆转速在143～147（r·min^-1）之间，供料速度在20.6～21．4（r·min^-1）之间时，加工质量较高，比容大于2．4（mL·g^-1）。
The effect of rotating speed of the screw, the temperature of the wail, and the feeding speed on product quality was investigated by experiments. The statistical model was established and the parameters optimized. The results indicated that the specific volume increases with increasing of the temperature of wall, the effect of rotating speed of screw and feeding speed on the specific volume is complex. When the temperature of the wall is between 160 - 166℃, the feedi.＇ng speed is between 20.6 -21.4r ·min^-1, rotating speed of screw is between 143 -147r ·min^-1, processing quality is better, specific volume is more than 2.4mL · g^-1.
