Single-Pass Drying Of Rough Rice Using Glass Transition Principles, George Owira Ondier
Graduate Theses and Dissertations
The objective of this research was to study the drying characteristics, milling quality, and functional properties of rough rice subjected to single-pass drying while controlling kernel material states. Drying experiments were conducted at 60, 70, and 80C and relative humidities ranging from 13 to 83%. High drying air relative humidities (greater than 63%) maintained both the kernel surface and core in a rubbery state during drying, whereas low drying air relative humidities caused rapid transitioning of the surface layers from a rubbery to a glassy state. Long-grain pureline cultivar, Wells, medium-grain pureline cultivar, Jupiter, and long-grain hybrid cultivar, CL XL729, …

Harvest moisture contents (HMCs) have been proven to play a role in rice quality, especially affecting head rice yield (HRY) due to fissuring or immature kernels. Differences in milling characteristics between samples having high and low level milling quality were studied in this experiment. Two hybrid, long-grain cultivars (CL XL729 and CL XL745) and two pureline, long-grain cultivars (CL 181 and Wells) were harvested at near optimal and low HMCs, representing high and low milling quality, respectively. Lots were dried to approximately 12.5 ± 0.5% and milled in triplicate for durations of 10, 20, 30, and 40 s. Results showed …
