| Paddy grains (rough rice) are categorized into two groups, awned and awnless paddies.The awn is a needle-like appendage that extends from the lemmas of the florets and is important domestication and agronomic traits in paddy. The aerodynamic properties of paddy grains and understanding the effect of awn on the aerodynamic properties of paddy are important information for grain harvest and postharvest process like cleaning, handling and for designing related systems. So in this research, aerodynamic properties of two local varieties of paddy (Hashemi and Gilaneh) and effect of awn as specific traits on aerodynamic properties were investigated in different moisture content. Terminal velocities were measured for awned and de-awned paddy grains using the... |

| Operation of a rotary dyer (RD) was compared with conventional fixed bed dryer (FBD). Drying time, trends of moisture content and specific energy consumption for water evaporation were investigated for drying of Iranian paddy cultivar., rice milling quality such as husking, milling recovery (MR) and head rice yield (HRY), were studied. Result showed that, using FBD decreased drying time and saved energy 8 and 6.78 percent, respectively. Specific energy consumption in NRD was 10.48 MJ per one kilogram of removed water and it was 6.82 percent more than FBD. Paddy moisture contents and temperatures differences at top and bottom layers of FBD were 2 percent and 6°C, respectively. High thermal stress in low layers of FBD increased grains cracking chance in... |
