Abstract
The feature of drying kinetices of five burely tobacco were studied with an online device of heat-ing-moisture treatment for analyzing,based on investigating the effects of temperature and relative humidity of medium on drying process,it was simulated using modified Fick's model.The results showed that the effective diffusion coefficient De value increases gradually with the temperature when humidity is 0.11 kg/kg,drying temperature is within 100~160℃,the De value reduces as humidity rises gradually when temperature is 130℃,dry air humidity is 0.05~0.23 kg/kg.
