On coix seed kernel,red beans,Chinese wolfberry leaf tea and milk as main raw materials,the best formula of process parameters was determined by using orthogonal test,formula milk which has different tastes and healthy function was made. Coix seed kernel,for example,the results showed that the best formula were found as follow:skim milk powder 4%,coix seed kernel juice 25%,sugar 8%,citric acid 0.4%and stabilizer 0.3%. Formula which has instant and optimal quality was achieved by the spray drying and orthogonal test. Ex-perimental results showed that the best technology parameters of the coix seed kernel formula were 130℃for in-let air temperature, 40℃for the outlet air temperature,150 mL/h for the feeding speed.%分别以薏米仁、红豆、枸杞叶茶与鲜奶为主要原料，通过正交试验确定各个工艺参数的最佳配方，制成不同口味且具有保健功效的配方奶，以薏米仁为例，试验结果表明，薏米仁奶最佳配方为脱脂奶粉4%，薏米仁汁25%，白砂糖8%，柠檬酸0.4%，稳定剂0.3%。后根据喷雾干燥设备进行喷雾干燥，通过正交试验确定各个工艺参数，以得到速溶性、品质优的配方奶粉。试验结果表明，薏米仁配方奶粉最佳工艺参数为进风温度130℃，出风温度40℃，进料速度为150 mL/h。
