| 目的 在保证喷涂雾化表征均匀性的前提下实现宽幅覆膜，提高覆膜的效率，以期得到均匀一致的大豆蛋白覆膜。方法 利用粒度仪测量不同干涉程度下的大豆蛋白液双枪喷涂雾化场的索特平均直径(Sauter Mean Diameter，SMD)，利用Spraylink软件处理粒度数据，得到粒度数据并对比。结果 双枪喷涂喷雾场的SMD随着液压的增大先增大后趋于平稳，随着气压的增大先减小后趋于平稳。当液压分别为0.08 MPa和0.16 MPa时，SMD基本不随偏转程度的变化而变化;当液压为0.24 MPa时，SMD随着偏转程度的增大而增大。双枪喷涂喷雾场的径向SMD从中心到边缘缓慢减小，在干涉区域内的轴向2点粒径基本相等。结论 当液压为0.08 MPa、气压为0.24 MPa、偏转角为0°时，SMD相对较小。文中的研究为实现宽幅覆膜奠定了理论基础。 |

| The work aims to achieve wide coating on the premise of ensuring the uniformity of spray atomization characterization and improve the efficiency of coating, in order to get uniform and consistent coating of soybean protein. The Sauter mean diameter of the spraying and atomizing field of soybean protein liquid was measured with a particle size meter under different interference degrees, and the particle size data were processed by Spraylink software, and the particle size data were obtained and compared. With the increase of hydraulic pressure, the SMD of the double-gun spraying and atomizing field increased first and then stabilized, and decreased first and then stabilized with the increase of air pressure. When the hydraulic pressure was 0.08 MPa and 0.16 MPa, SMD did not change with the change of the deflection degree. While when the hydraulic pressure was 0.24 MPa, SMD increased with the increase of the deflection degree. The radial SMD of the double-gun spraying and atomizing field decreased slowly from the center to the edge, and the diameters of the two axial points in the interference region were basically equal. When the hydraulic pressure is 0.08 MPa, the air pressure is 0.24 MPa. When the deflection angle is 0°, SMD is relatively small. The research in this work lays a theoretical foundation for the realization of wide coating. |
