In this paper a pressure gradient on a bean seed layer in dependence on a bed height and an airflow velocity in a cylindrical dryer research are presented. A hydraulic resistance along the bed was described by Ergun equation. An airflow resistant coefficient through the bean seed bed was determined.

Keywords: bean seed, pressure gradient along a bed, flow resistant coefficient
