Abstract

One of the stages of post-harvest handling is drying rice. The rice drying process for this is still done by direct drying under the sun. The drying process depends on the amount of solar radiation, especially the rainy winter weather. The results showed that the air flow rate and the number of heating pipes are very influential on the energy supplied air to evaporate the water in the grain. Where the highest energy 3.948.7353,979 Watt blower, wind speed 13 m / s with variations of two heating pipes, while the lowest energy 469,041.223 Watt blower, wind speed 13 m / s with variations of three heating pipes. The air flow rate and the number of heating pipes also affect the thermal energy which can be used for drying grain. Where the highest energy 85968.800 Watt at a speed of 13 m / s with variations of three pieces of pipe, while the lowest energy 31426.867 Watt at a speed of 13 m / s with variations of the pieces of pipe. The efficiency is very dependent on a hot air flow rate and the number of heating pipes, if the energy received high grain, the higher efficiency is obtained. Where the highest efficiency 98.73% at a wind speed blower 13 m / s with two heating pipes, while the low efficiency of 2.81% at a wind speed blower 7 m / s with a single heating pipe
