| 目的 研究不同喷涂参数下大豆蛋白喷涂不均匀性，以提升蔬菜复合纸的热封效果。方法 利用摄像机采集喷涂试样，并运用Matlab编程对喷涂后的硫酸纸进行图像处理分析，得出大豆蛋白涂层所占的面积比，最后运用Origin分析不同喷涂参数对大豆蛋白涂层所占面积比的影响。结果 当液压或气压在120～220 Pa时，大豆蛋白涂层所占的面积比随液压或气压的变化先增后减；当流量在35～60 mL/min时，大豆蛋白涂层所占的面积比随流量的变化先增加再持平，最后减少；在同一参数的不同横向测试点下，大豆蛋白涂层所占的面积比在喷涂区域两端较小，中间较大。结论 液压、气压及流量对大豆蛋白液喷涂不均匀性有很大影响，且单个因素下液压160 Pa、气压180 Pa或流量50 mL/min时，喷涂效果更好。 |

| The work aims to research the unevenness of soybean protein spraying under different spraying parameters, so as to improve heat sealing effects of vegetable composite paper. The spraying samples were collected by the camera, and the images of vegetable parchment after spraying were processed and analyzed by Matlab programming. The area ratio of soybean protein coating was obtained. Finally, the influence of different spraying parameters on soybean protein coating area ratio was analyzed by Origin. When hydraulic pressure or air pressure was 120~220 Pa, the area ratio of soybean protein coating increased first and then decreased with the change of hydraulic pressure or air pressure. When the flow rate was 35-60 mL/min, the area ratio of soybean protein coating increased first and then leveled up, and finally decreased with the change of flow rate. At different transverse test points of the same parameter, the area ratio of soybean protein coating was relatively small at both ends of spraying area and relatively large in the middle of spraying area. Hydraulic pressure, air pressure and flow rate have a great impact on the soybean protein liquid spraying unevenness, and under a single factor, when the hydraulic pressure is 160 Pa, air pressure is 180 Pa or flow rate is 50 mL/min, the spraying effect is better. |
