Abstract
Abstract The purpose of this study was to determine the amount of heat energy in the paddy drying process using a fluidized bed dryer. The method used in this research was an experimental method using an energy balance. This test was carried out using a fluidized beds dryer, with paddy material, where the paddy was dried at a certain temperature with 3 mass treatments, namely 5, 6 kg, and 7 kg with an air velocity of 21 m/s. The results showed that the total energy that enters the drying chamber for a mass of 5 kg material is 1,022 kJ with a useful energy of 1.339 kJ. The energy that enters the drying chamber for a mass of 6 kg is 1,043 kJ with a useful energy of 2.192 kJ. For a mass of 7 kg of material, the energy that enters the drying chamber is 1,187 kJ with a useful energy of 3.578 kJ.
