Abstract

The effects of freeze-thaw processing on the characteristics of hot-air drying and the coefficients of moisture diffusion in Malus domeri (Bois) chev were investigated. The results showed that the freeze-thaw pre-treatments had significant effects on drying characteristics. It was found that freeze-thaw pre-treatments could significantly shorten the drying period and increasing the drying rate. Logarithmic model provided better simulation of drying curves for freeze-thaw M. domeri (Bois) chev. at different drying conditions. The results indicated that Deff increased with the increasing of times of freeze-thaw.
