| 摘 要： | 采用太阳能与西北干燥空气资源合理结合的方式,对苹果切片进行脱水干燥实验研究,对果片厚度、装载量、风速对苹果的干燥速率和生产能力的影响进行试验,得出最佳工艺参数。结果表明,果片厚度和装载量对干燥速率和生产能力均有显著影响,而风速对干燥速率和生产能力影响不显著。采用切片厚度5mm的苹果片,装载量5kg/m2,风速1.5m/s的太阳能干燥工艺,可以使干燥速率和生产能力的综合效果较好。将500kg的苹果进行太阳能干燥,84h后,得到终水分为15%的干果片44.3kg,成品率为8.8%。与传统热风干燥相比具有明显的节能效果,节能率为69.2%。

| Abstract: | The drying process of fresh apple slices with solar energy combined with abundant dry air resource in northwest China was investigated. The effects of apple slices thickness and loadage as well as air flow rate on water loss rate in apple slices were analyzed in single factor experiments. Based on this, the optimal value of three parameters were determined using orthogonal array design for reaching a good compromise between drying rate and productivity. Results indicated that both thickness and loadage of a... |
