| 摘 要： | 为提高漂白紫胶产品质量及生产效率,采用微波-真空干燥漂白紫胶研究了不同压强、微波功率和干燥时间对漂白紫胶产品颜色指数和含水率的影响,用响应曲面法（RSM）设计试验并建立了该工艺条件的拟合方程。结果表明,拟合方程的拟合度较高,所建立的数学模型可以用于描述漂白紫胶的微波-真空干燥。漂白紫胶微波-真空干燥的最优条件：干燥压强为3.0 kPa,微波功率为795 W,干燥时间为30 min。在优化条件下进行了验证实验,得到了颜色指数为0.9、含水率为0.028 9kg水/kg干料的产品。

| Abstract: | In order to improve product quality and production efficiency,effect of different pressure,microwave power and drying time on color index and moisture content of the products were studied by microwave-vacuum drying process of bleached shellac.Fitting equation of the process conditions was set up by response surface method（RSM） experimental design.Results showed that the equation was well fitting and the established mathematical model can be used to describe microwave-vacuum drying of bleached shellac.The optimal process may be taken at the pressure of 3 kPa with 795 W microwave power for 30 min drying.Under the optimal conditions,it can be achieved products with color index of 0.9 and moisture content of 0.028 9 kg water/kg dry materials. |
