摘要: 对马铃薯进行高压电场干燥和热风干燥对比实验,及对其干燥后的维生素C含量的检测。结果表明:高压电场能够加速马铃薯的干燥,且能够很好的保留维生素C,高压电场的马铃薯干燥样品的维生素C含量比热风干燥样品高43.5%。分析了高压电场干燥机制,认为是电场中载能离子注入、非均匀电场和离子风外部吹动三部分合一的过程,即“电场能传质”。

Abstract: The parallel drying experiments of potato were made with both High Electric Drying(HED) and Heat Drying. Thevitamin C retained in experiments were assayed. The results indicated that the drying rate of potato was higher on high electricdying and the vitamin C could be retained more than on heat drying(43.5%) more. The mechanism of high electric drying wasenvisaped. And it was thought that the drying mechanism on high electric field produced the injecting of ion, the effect of unevenelectric field and the formation of ion wind.
