5XS系列脱绒棉种色选机参数优化试验

5XS series color sorting cottonseeds parameter optimization

为探讨5XS系列脱绒棉种色选机工作参数的最佳匹配,以色选机的色选精度和带出比作为评价指标,对色选机背景板角度、工作压力、色选灵敏度和种子流量等试验因素进行单因素和正交试验。单因素试验表明:背景板角度、工作压力和色选灵敏度均对色选精度和带出比2个指标有显著影响。正交试验表明:背景板角度为135°,工作气压为250kPa,色选灵敏度为242时,色选精度达到98%,带出比为1∶0.42。

To explore the 5XS series color sorting cottonseeds machine working parameters of the best match to the color sorting machine precision, with the ratio and cotton seed crushing rate as the evaluation indexes, the single factor and orthogonal tests were conducted with different background plate angle, work pressure, color sensitivity and seed flow values. Single factor tests showed that the effects of background plate angle, work pressure and color sensitivity on color accuracy and carryover ratio were significant. Orthogonal tests showed that with background plate angle 135°, working pressure 250 kPa, sensitivity 242, the color sorting accuracy was up to 99.5%, and the carryover ratio was 1:0.39.
