ABSTRACT

In the present study two local cultivars of paddy (long and medium grain size) were dried in thin layer by three different methods included indirect active solar dryer, mixed-mode active solar dryer and continuous dryer, at three temperature levels of 35, 45, and 55℃. Also, paddy was dried by sundry method as the traditional and common used method (control treatment). Energy consumption for different parts of aforementioned dryers was practically determined. Total drying energy per kilogram of dry mass of head rice yield (specific energy consumption) was calculated. Results indicated that medium size grains result more head rice yield than longer ones. No significant difference was observed for head rice yield form indirect and mixed-mode solar drying. Drying temperature significantly influenced on head rice yield and the specific energy consumption, so that the lowest ratio was obtained at 35℃. Considering low specific energy consumption and drying time duration, continuous dryer acted more efficient than others.
