The bulk volume shrinkage was linearly related to instantaneous grain
moisture reduction. The shrinkage coefficient was found to be primaril
y a function of air relative humidity. The Bakker-Arkema's bulk grain
drying model was modified to incorporate the shrinkage equation. A cor
rection factor for thin layer drying equation was also introduced to r
educe deviation between the experimental and simulated moisture conten
t. The Bakker-Arkema model showed significant improvement due to these
modifications.
