摘　　要：为研究不同热泵干燥条件对生姜品质的影响,以大姜块为原料,以干燥速率、姜粉色泽、复水性和姜辣素提取率为指标,通过单因素试验和响应面试验研究了干燥温度、切片厚度和装载量对干燥后生姜的品质和姜粉品质的影响。试验结果表明,生姜热泵干燥的最优条件为温度74℃,切片厚度5 mm,装载量4.85 kg/m2,在这个条件下的干姜片姜辣素含量最高,姜片复水性较好,姜粉色泽鲜亮,干燥速率较快。In order to obtain high quality dried ginger,the optimal drying technology of ginger by heat pump was studied.Using ginger as raw material,the effects of drying temperature,slice thickness and loading volume on the drying of ginger by heat pump were analyzed through single factor experiment and response surface test.The quality of dried ginger and ginger powder was studied using drying rate,ginger powder color,rehydration and gingerol content as indexes.The results showed that the optimal conditions for ginger heat pump drying were temperature of 74℃,slice thickness of 5 mm,and loading capacity of 4.85 kg/m2.Under these conditions,the content of gingerol in dried ginger slices was the highest,the rehydration of ginger slices was better,the color of ginger powder was brighter,and the drying rate was faster.
