Abstract

The physical and aerodynamic properties of grain are very necessary in the development of pneumatic grain handling. These properties are influenced by moisture content and grain type. This study aimed to investigate the effect of moisture content and grain type on the physical and aerodynamic properties of rough rice and corn. In this study, three types of rough rice and corn, each in three levels of moisture contents were investigated. A completely randomized design, factorial 3 x 3 was used in the research. It was found that moisture content, grain type, and the interaction of these two factors significantly influenced most of the physical and aerodynamic properties of rough rice and corn. The relationships between these two properties with moisture content mostly could be expressed as the linear equations. There was no single equation that could be used to predict terminal velocity accurately within the range of moisture content studied.
