| Abstract | Rough rice and soybeans were tested for their
resistance to airflow in both vertical and horizontal
airflow directions and resulting air pressure distribution
in the grain mass.
Rough rice showed higher airflow resistance than
soybeans. In both grains, the resistance to airflow
decreased with an increase in moisture content. However, an
increase in resistance to airflow was observed with an
increase in bulk density and grain depths.
Resistance to airflow in rough rice and soybeans was
found to be greater in vertical airflow direction than the
horizontal airflow direction. The resistance to airflow in
the horizontal direction was about 0.4 and 0.2 the
resistance to airflow in the vertical direction for rough
rice and soybeans, respectively.
Grain bed depth had the greatest effect on airflow
resistance in comparison with moisture content and bulk
density based on ANOVA results.
The nonlinear regression models for each grain at each
airflow direction adequately described the relationship
between the static pressure drop, airflow rate, bulk
density, grain moisture content, and bed depth.
The pressure pattern predictions based on the equations
obtained from vertical airflow direction give about 12 and
30 percent less error for rough rice and soybeans,
respectively, compared with the predictions based on the
equations obtained from horizontal airflow direction. |
