Study on Drying Experiment of Potato on High Electric Field

Abstract

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.

Key words: high electric field, potato, drying
