Household Paddy Dryer Controlled by an Electronic Circuit

Abstract

This research article presents the design and development of a household rice dryer controlled by an electronic circuit to address the challenges farmers face in drying paddy, such as the large space and time required, as well as the unpredictability of weather conditions. The developed dryer can hold up to 40 kilograms of rice and is equipped with three moisture control sensors, a moisture removal fan, and an electric motor to enhance drying efficiency. The experiment results show that the dryer can reduce the moisture content of paddy from up to 40% to approximately 7.2%-15%. Additionally, it was found that the dryer operates effectively within the weight range of 0-40 kilograms, but exceeding this limit causes an overload, resulting in the motor stopping.
