• Glass transition
• Relative humidity
• Single pass
• Tempering

The objective was to study the drying characteristics and milling quality of rough rice subjected to single-pass drying while controlling kernel material states. Drying experiments were conducted at 60, 70, and 80 degrees C and relative humidities ranging from 13 to 83%. For all drying air temperatures and tempering conditions, milling quality was not significantly different from the controls when the relative humidity of the drying air was maintained above 63% (kernel core and surface maintained in a rubbery state) and rice was tempered immediately after drying, in sealed plastic bags and at the drying air temperature, for at least 60 min.
