摘要
为探究间歇微波—热风耦合干燥花生的最佳工艺参数,借助响应面优化分析方法,以花生干燥速率和干燥能效的综合评分为响应值,确定了花生间歇微波—热风耦合干燥的最佳工艺参数为:热风温度45℃,微波强度1.25W/g,微波间歇比1.10。该条件下,花生间歇微波—热风耦合干燥速率为0.517g/min,能效为0.433 MJ/g,干燥综合评分0.710,模型误差小于5%。基于此工艺参数探究该干燥方式对花生脂肪酶活动度、硬度、颜色和脂肪酸组成的影响。结果显示,间歇微波—热风耦合干燥是一种高效的干燥技术,能保证花生的品质。
In order to explore the optimal process parameters of intermittent microwave-hot air coupled peanut drying,the optimal process parameters of peanut intermittent microwave-hot air coupled drying were determined using the response surface optimization analysis method.The comprehensive score of peanut drying rate and drying energy efficiency as response values.The optimal conditions were as followed:hot air temperature 45℃,microwave intensity 1.25 W/g,microwave intermittent ratio 1.10.Under these conditions,it was verified that the peanut intermittent microwave-hot air coupling drying rate was 0.517 g/min,the energy efficiency was 0.433 MJ/g,the comprehensive drying score was 0.710,and the model error was less than 5%.Based on this process parameter,the effects of this drying method on peanut lipase activity,hardness,color and fatty acid composition were explored.The results show that intermittent microwave-hot air coupling drying is an efficient drying technology,which can guarantee the quality of peanuts.
