Abstract
The drying methods of paddy dryers had shifted from a bed type to a circulation type, and now its mainstream is on the intermittent drying method using the tempering period. To improve the performance of paddy dryers maintaining the quality of rice, it is important to understand the moisture transportation process between the husk and brown rice and apply this knowledge to the development of new paddy dryers. In this study, various drying characteristics were examined by using test equipment and then the drying performance was confirmed with a prototype dryer. The test results cleared the methods of improvement in paddy drying speed and energy saving.
