Abstract
Abstract. The main goal of this research was to study the effects the utilization of heated rice husk (20oC to 107oC), residence time (0 h to 5 h) and rice husk to rough rice ratios (1:2, 1:4, 1:6, 1:8 and 1:10 kg kg-1) on the moisture reduction and drying rate. Heated rice husk, in the present study, was used as a solid heat transfer medium and a moisture adsorbent during the drying process. Increasing the rice husk to rice ratio showed a lower temperature during the first hour of the cooling stage, particularly with the higher temperatures levels greater than 40°C. The highest temperature range was very clear at the husk temperature level of 107°C. A 4.0% moisture reduction of rough rice could be achieved by employing heated rice husk at 107oC and mixing the rice husk to rough rice by 1:2 weight basis. Increasing the husk to rough rice ratio decreased the rough rice-drying rate. The highest drying rate of 3.87%/h was achieved during the first hour after the mixing process under the husk temperature of 97oC and the husk to rice ratio of 1:2. The first hour of the drying process proven to be the most effective duration as evident by the highest drying rate.
