胡萝卜冷冻干燥能耗和生产率的多目标优化
Multiple optimizations of energy consumption and productivity during freeze drying process of foods
摘要
Abstract
Freeze drying experiment of carrot was carried out on a freeze drying dig. Tests were performed using quadratic orthogonal regression method. The quadratic regression equation of energy consumption per water and productivity were obtained by SAS software. In order to accomplish comprehensive optimization of energy consumption per water and productivity, the multiple optimal methods were utilized based on linear weighting and the objective function established. The optimization was carried out by MATLAB 7. 0 which executed the program. The results showed that the optimal operating conditions were as follows: thickness is 8. 896 8 mm, pressure in drying chamber is 33. 572 9 Pa, temperature of heating sheet is 63.248 5℃.关键词
