分离技术在D90脱盐乳清液工业化生产中的集成应用

Integration application of separation technology in the industrial produced D90 desalted whey liquid

将膜分离技术、离子交换技术、电渗析技术集成应用于脱盐乳清生产线上,采用四因素五水平二次回归正交旋转组合实验设计,研究D90脱盐乳清液最佳优化工艺条件选择进料质量分数、进料温度、纳滤压力、电渗析温度进行单因素实验,并验证回归模型的显著性。结果表明,生产D90脱盐乳清液的最佳工艺条件:进料质量分数16.03%,进料温度11.59℃,纳滤压力2.56 MPa,电渗析温度36.79℃。

In this study membrane separation, electrodialysis and electrodialysis were integration applied in desalted whey production. By the five levels of the four factors quadratic regression orthogonal rotation combination design, to research the best DWP90 optimize the process conditions. This study selected the feed concentration, feed temperature, nanofiltration pressure and electrodialysis temperature for single-factor test, and verify its significant. The results show that the DWP90 production optimum conditions： the feed concentration value of 16.03%, the feed temperature of 11.59 ℃, nanofiltration pressure of 2.64 MPa, and electrodialysis temperature of 36.79 ℃.
