Groundnut Roasting Machine using Induction Heating

Traditional groundnut roasting methods that use firewood and gas contribute significantly to deforestation, carbon emissions, and health risks for street vendors. To address these issues, this project proposes a solar-powered induction heating groundnut roaster that is energy-efficient and environmentally friendly. The system incorporates a Zero Voltage Switching (ZVS) converter for improved efficiency and reduced switching losses [1][2][7]. An Arduino microcontroller automates temperature monitoring and control, enabling precise roasting and minimizing human intervention [3][11]. A motor-driven stirrer ensures uniform heat distribution, enhancing the overall roasting quality [5][6]. The system is powered by a solar photovoltaic panel with a battery backup to ensure uninterrupted operation even during low sunlight periods [4][12]. This innovative solution supports clean energy use, reduces operational costs, and improves the livelihood of street vendors by providing a safer and more reliable roasting method.
