drying Photovoltaic blower

This study focuses on the design, fabrication, and performance evaluation of a solar thermal dryer developed using locally available materials to enhance the drying of agricultural products in both rural and urban environments. Traditional open-air drying methods commonly practiced in Nigeria are fraught with challenges such as contamination, theft, unfavorable weather, and inconsistent drying rates, leading to significant post-harvest losses. To mitigate these limitations, a solarpowered thermal drying system was developed to harness the abundant solar energy available in tropical regions. The research methodology involved a comprehensive review of literature on solar energy utilization, the development of suitable design concepts, determination of relevant design and environmental parameters, material selection, fabrication, and experimental testing. The solar dryer design integrates a photovoltaic-powered air blower and a thermally heated chamber, providing controlled airflow and consistent heat distribution for effective moisture removal. Findings from related studies and prototype evaluations revealed that solar thermal dryers offer improved drying efficiency, reduced drying time, and enhanced product quality compared to conventional methods. The project demonstrates the potential for affordable, energy-efficient, and environmentally sustainable drying technology adaptable for small-scale farmers and households. Furthermore, the design can be scaled up for commercial use, promoting local manufacturing, job creation, and the wider adoption of renewable energy technologies in Nigeria.
