Airflow resistance of marigold flowers dried in an experimental rotary dryer was determined by measuring pressure drop versus airflow through a bed of flowers for depths ranging from 0.15 to 1.0 m and flower moisture contents ranging from 10% to 85% (wet basis). A single power relationship adequately described pressure drop for a broad range of flower moisture conditions and airflow. Bulk density varied from 118 to 276 kg/m3 for bed depths and flower moisture contents ranging from 0.15 to 1.0 m and 10% to 85%, respectively. Moisture content had the most effect on bulk density.
