| 目的 研究大豆蛋白喷涂液雾化场的粒度分布，及喷涂过程中喷涂参数对大豆蛋白液雾化液滴粒径的影响，从而在蔬菜复合纸覆膜成型过程中选择最优喷涂参数。方法 利用激光粒度仪测量不同喷涂参数下大豆蛋白液喷涂雾化场的粒度分布，并通过数据分析软件Origin研究喷涂参数对大豆蛋白液喷涂雾化粒度的影响。结果 喷涂参数相同时，喷涂雾化场中随着轴向距离的增加，大豆蛋白液液滴粒径先显著减小后趋于稳定；喷涂雾化场中同一轴向位置随着径向距离的增加，大豆蛋白液液滴粒径呈减小趋势。在喷涂雾化场同一测量点，随着喷涂气压的增大，大豆蛋白液液滴粒径逐渐减小；喷涂液压对大豆蛋白液液滴粒径没有显著影响。结论 喷涂气压为0.2 MPa，喷涂液压为0.16 MPa，喷涂雾化场轴向30 cm平面内，大豆蛋白液雾化液滴粒径较小且均匀。 |

| The work aims to investigate the particle size distribution in the soy protein liquid atomization field and the influence of spray parameters on soybean protein liquid atomization droplet size in the process of spraying, thus to choose the optimal spray parameters in the process of preparing coated vegetable composite paper. Particle size distribution in atomization field of soybean protein liquid was measured under different spraying parameters by using laser particle size instrument, and the effects of spraying parameters on atomized particle size of the soy protein liquid was analyzed through the data analysis software Origin. When spraying parameters were certain, atomized droplet diameter of soy protein liquid significantly reduced before they were stable with the increase of axial distance in the spray atomization field. Soy protein liquid droplet diameter at the same axial location of the spray atomization field showed a trend of decrease with the increase of radial distance. Soy protein liquid droplet size at the same test point of spray atomization field decreased with the increase of spray air pressure. Impact of spray hydraulic pressure on soybean protein liquid droplet size was not significant. In conclusion, the soy protein liquid droplet size in the plane 30 cm from the nozzle in spray atomization field is smaller and more uniform when the spray air pressure is 0.2 MPa and the spray hydraulic pressure is 0.16 MPa. |
