“…Generally the model predlcted temperatures better in a high temperature drying than in a low temperature drying, and with respect to grain type, better for wheat than for canola. Mathematica/ modeling The literature contains a number of studies on airflow distribution in graln bins either experimentally (Brooker, 1959) or mathematically (Brooker, 1961;Segerlind, 1982;Miketinac & Sokhansanj, 1985;Gu et a/., 1996). These studies were focused on air pressures within the grain mass.…”

This paper discusses recent advances in cereal drying. It focuses on mathematical modeling of convective heat and mass transfer using air as the drying medium. The mathematical modeling of air distribution follows conservation of momentum and a constituent equation relatinng the velocity of air to its static pressure. The paper presents data obtained from a series of detailed wheat drying experiments. It is shown that the existing simulation models can be improved once the thin layer drying equation is uplated spatially and temporally within the bulk grain. The use of variable properties in calculating transient moisture contents and temperatures also improves the accuracy of mathematical simulations.
