The rice drying process in a rotary dryer gives the benefit of producing uniformly dried rice in a short drying time. This work investigated a rotary dryer's efficiency and heat consumption at various temperatures (40, 50, and 60 °C) and capacities (10, 20, 30, and 40 kg). When loaded with 10 to 30 kg of rough rice and operated at 60 °C, the dryer produced dry rice with 14% w.b. moisture content for less than 3 hours. The energy efficiency and consumption were evaluated based on the experiment and theoretical analysis. According to the observation, a high temperature significantly shortened drying time. Thus, the total energy and fuel consumption decreased even at the higher capacity. The lowest carbon dioxide emission was achieved at the highest temperature and capacity.

Keywords: energy consumption; energy efficiency; fuel consumption; moisture content
