Design and Implementation of an Automatic Indirect Hybrid Solar Dryer for Households and Small Industries

The use of heat exchangers for the process of energy conversion from rice husks to thermal as an alternative to replacing sun drying. Drying with rice husk energy and heat exchanger does not depend on the weather. To determine the effectiveness of this dryer, a thermal evaluation was carried out on the heat exchanger and drying chamber with a sample of 4 kg of shelled corn. The test results showed an increase in the drying temperature of 112.31%. The increase occurred from an average environmental temperature of 30.30oC to an average drying room temperature of 64.33oC. The temperature increased significantly by 34.03oC. This increase in temperature is a result of the use of a black steel pipe heat exchanger, rice husks, and the number of holes in the furnace wall that function as air circulation to help the process of burning rice husks. The distribution of the average temperature on each shelf in the drying room is rack 1 (Ts1) 76.79oC, shelf 2 (Ts2) 65.24oC, shelf 3 (Ts3) 59.77oC, and shelf 4 (Ts4) 55. 52oC.
