摘要
采用基于中心组合设计的响应曲面法,考察了干燥温度、时间和物料量的交互作用对单宁锗相对脱水率的影响,结果表明:实验因子与单宁锗相对脱水率的关系符合二次方程模型。在分析了各个因子的显著性和交互作用后,得到的最优化工艺条件为:干燥温度90℃、时间7min、物料量12 g,在此条件下,单宁锗实际相对脱水率为96.42%,与预测值基本吻合。
Microwave drying temperature,time and sample weight as experimental variables were investigated to test the effects on relative dehydration rate using response surface methodology（RSM） based on the central composite design（CCD）.The results showed the relation between variables to the relative dehydration rate agree with the quadratic model.According to analysis of the significance and the interaction of each factor,the optimum condition was found as follows：microwave drying temperature is 90℃,time is 7min and sample weight is12g.Under the optimum condition,the relative dehydration rate of tannins germanium acid was 96.42%,the results indicated that the experimental data basically agreement with the predicted values.
