摘　　要：为对牦牛奶粉喷雾干燥条件进行优化,在单因素实验的基础上,采用L9(34)设计对进风温度,进料速度以及干物质含量进行优化探讨。结果表明:最佳喷雾干燥条件为进风温度为170℃,进料速度为10.4m L/min,干物质含量为8.7g/100g;进风温度对牦牛奶粉的出粉率影响显著(P<0.05)。To investigate spray drying conditions of Yak Milk Powder, orthogonal test（L9 （3^4） ）was adopted to study the key parameters of inlet air temperature, feed flow rate and total solids effect on the optimization of the process. The results indicated that the optimum conditions for the flour yield rate of Yak Milk Powder to be ： inlet air temperature of 170℃, feed flow rate of 10.4ml/min and total solids of 8.7g/100g. Inlet air temperature has significant influence on yak milk yield （ P 〈 0.05 ）.
