Performance Evaluation of Paddy Rice Pneumatic Dryer

Abstract

This research was carried out to study the drying of paddy using a developed pneumatic dryer by the cyclone and without cyclone installation. In this study, Thai jasmine rice 105 variety was selected as a sample in the experiment. The effect of drying behavior, specific energy consumption (SEC), drying rate (DR) and percent of head rice yield were evaluated as the performance. For drying experiment, 40 kg of paddy was dried at drying temperature of 80C. The result shown that the drying system without cyclone gives a higher rate of moisture reduction than the cyclone installation. Based only on energy utilization during the process, the highest SEC of 7.25 MJ/kgwater occurs on the drying at airflow rate of drying 0.0512 m3/s (50 Hz on blower motor invertor) by without cyclone. For the dried product quality, the highest head rice yield of 36.84% on the drying at air flow rate of drying 0.0631 m3/s (55 Hz on blower motor invertor). Breakeven at a production level of 1.6 ton/year
