DESIGN AND IMPLEMENTATION OF HOME DRYER MACHINE USING SOLAR ENERGY BASED AUTOMATION SYSTEM

Abstract

Among the many difficulties the agriculture industry encounters are post-harvest losses brought on by labour-intensive and inefficient traditional drying techniques. Open sun drying exposes items to environmental risks like rain, dust, and bugs, which lowers quality and increases spoiling in many rural regions. Additionally, using gasoline dryers raises issues with environmental impact, high operating costs, and mechanical failure. In order to address these problems, this study suggests creating and implementing an automated solar dryer that makes use of cutting-edge technologies. To improve the efficiency of the drying process, the research combines automated technology with solar energy. The dryer considerably improves product quality by ensuring steady and ideal drying conditions through the integration of phase change materials and thermal storage. Automation characteristics enable continuous functioning without human supervision by reducing the need for manpower. This study is anticipated to produce better drying efficiency, higher production, and better local community food security. The solar dryer will be made of easily obtained materials, guaranteeing its affordability and practicality in remote areas. This automated solar dryer uses the following technologies: a thermocouple PT100 temperature sensor accurately monitors the internal temperature, providing real-time feedback for adjustments; a charger controller manages the battery charge, ensuring that energy is stored efficiently for use during non sunny periods, thereby enhancing the system's reliability; a thermostat temperature controller precisely regulates the temperature, ensuring ideal drying conditions; a PTC heater provides efficient heating; and a cooling fan maintains airflow and temperature stability within the drying chamber. This project intends to decrease agricultural waste while simultaneously increasing the use of renewable energy, sustainable development, and environmental preservation. The study's findings demonstrate the potential of automated solar dryers as a game-changing tool for the agricultural industry that will improve post-harvest management while lowering expenses and having a less negative impact on the environment. Ultimately, the introduction of such systems could benefit the livelihoods of farmers and promote food security in rural areas.
