| 摘要: |
| 目的 研究大豆蛋白喷涂在硫酸纸上的平均密度，以及喷涂参数和带速对喷涂平均密度的影响。方法 首先通过摄像机采集喷涂图像，再运用Matlab软件处理计算大豆蛋白液所占面积比。面积比越大，则大豆蛋白喷涂效果越好，并利用响应面分析法研究喷涂参数及带速对喷涂平均密度的影响。结果 当液压为159 Pa，气压为180 Pa，带速为11.93 mm/s时，大豆蛋白液所占面积比可达79.9079%，此时最佳。结论 单个因素中液压和带速对喷涂平均密度有显著影响。通过分析软件建立了大豆蛋白液所占面积比与喷涂参数及带速之间的关系模型，并得到了最佳喷涂条件。 |

| Abstract: |
| The work aims to research the average density of soybean protein spraying on the parchment paper and the influence of spraying parameters and belt velocity on the average spraying density. Firstly, the spraying image was collected by the camera and then the area ratio of soybean protein solution was processed and calculated by software Matlab. The larger the area ratio was, the better the spraying effect of soy protein was. The effect of spraying parameters and belt velocity on the average spraying density was also studied based on response surface analysis. When hydraulic pressure was 159 Pa, air pressure was 180 Pa and belt velocity was 11.93 mm/s, the area ratio of soybean protein solution could be up to 79.9079%, which was the best. Among the single factors, the hydraulic pressure and belt velocity has a significant effect on the average spraying density. The relational model between the area ratio of soybean protein solution and the spraying parameters & belt velocity is built through analysis software, and the optimal spraying conditions are identified. |
