AB - In this study, intermittent drying process of corn was studied numerically  for various intermittent periods and drying air temperatures. An Arrhenius  type diffusion coefficient D=e(-b/T) 10-9 m2 s-1 was proposed for the  moisture diffusion inside the corn. Numerical simulations were performed by  choosing the suitable value for drying constant b that yields the best  agreement with experimental drying rates. The experimental results were  obtained via an experimental setup for intermittent periods of 30 and 60  min. and drying air temperatures of 40°C, 50°C, 60°C and 70°C. The results  show that overall agreement between the experimental and theoretical  prediction is good. On the other hand, the theoretical results overestimate  the moisture ratio at the initial stage and underestimate it at the later  stage of drying.
