摘  要:
以新疆地区红枣为研究对象,采用变温压差膨化干燥,在前期单因素试验的基础上,采用三因子二次回归正交旋转组合设计,分析预干燥时间、膨化温度和抽空时间对产品水分含量、膨化度和色泽的影响。通过响应面优化工艺,得出红枣变温压差膨化干燥的最佳工艺是:预干燥时间4 h,膨化温度72.10℃,抽空时间84.69 min。

摘  要:
Based on the anterior monofactorial tests for explosion puffing drying of Xinjiang red date at variable temperature and pressure difference,the effects of predrying time,puffing temperature and vacuum drying time on the product' s water content,puffing degree and color were analyzed by means of a central composite rotatable design(CCRD).The optimization of the drying process by response surface methodology showed that the optimal drying process was predrying for 4 h,puffing at 72.10 ℃ and vacuum drying for 84.69 min.
