摘要
为了研究在真空干燥条件下胡萝卜的干燥特性,进而为其真空干燥确定适宜的工艺参数,选用5种真空度分别为0.05MPa、0.06MPa、0.07MPa、0.08MPa和0.09MPa,在4种干燥温度40℃、50℃、60℃和70℃条件下对鲜胡萝卜进行脱水干燥试验,测定不同干燥工艺条件下胡萝卜的干燥特性,并进行复水比较试验。试验结果表明:0.07MPa和60℃为胡萝卜真空干燥制的适宜工艺条件,复水最佳条件为温度60℃,时间为90min。
In order to study the drying characteristics of carrot vacuum drying and to determine the suitable technological parameters for drying procedure, carrot was dehydrated under 0.05, 0.06, 0.07, 0.08 and 0.09 MPa vacuum drying condition at 40, 50, 60 and 70℃ respectively. In the drying procedure the weight of test samples and the drying velocity were determined at different stage. A dehydration test was made for the dried carrot in various treatments. The results showed that the suitable vacuum drying technological parameters were 0.07MPa in combination with 60℃ and the best dehydration water temperature was 60℃ for 90 min.
