中文摘要:
      目的 为了分析蔬菜复合纸的喷涂效果, 研究大豆蛋白喷涂液在不同的蛋白液浓度及喷涂条件下雾化角的变化与雾化整体形貌。方法 首先通过高速摄像机采集喷涂图像, 其次利用Matlab图像处理功能计算雾化角, 并通过响应面分析法分析大豆蛋白浓度及喷涂条件对雾化角的影响。结果 当液压大、 气压小时, 喷涂雾化效果较差; 随着气压的增大, 雾化效果逐渐变好。单因素中浓度和气压对大豆蛋白喷涂液的雾化角有显著影响, 并通过分析软件得到了雾化角与喷涂工艺参数和浓度之间的关系模型。结论 得到了最佳的喷涂条件, 大豆蛋白质量分数为11.13%, 气压为2 MPa, 液压为1.64 MPa,此时的雾化角可达到81.4690°。
英文摘要:
      The influence of different soy protein spray coating dispersion concentrations and spraying conditions on the atomization angle and the atomization overall morphology was studied to evaluate spraying quality on vegetable composite paper. The high-speed camera was used to collect images of spraying and then the spray angle was calculated through the image processing function of Matlab software. The effect of the concentration and process parameters on spray angle was also analyzed according to the response surface methodology. When the hydraulic pressure was high and the air pressure was low, poor atomization was generated. With the increase of air pressure, the better atomization performance was achieved. In the aspect of single factor, concentration and air pressure had a significant effect on the spray angle. The relative model of spray angle, process parameters and concentration was established by analytical software. The optimal spraying condition was obtained as follows. The spray angle of SPSCD was up to 81.4690° , when the concentration of SPSCD was 11.13%, the air pressure was 2 MPa, and the hydraulic pressure was 1.64 MPa.
