Storing food for long periods of time is difficult in many areas of the world due to a lack of electricity, particularly in developing regions. People that depend on pre-packaged meals, such employees, students, and tourists, are especially affected by this problem. sun tiffin warmers, which use sun energy to keep food at a constant temperature, are one answer to this problem. An efficient heating element, thermal storage, a solar reflecting mirror, a phase change material (PCM), and a small, portable tiffin make up the system. In order to maintain a constant temperature regardless of the weather, the system makes use of thermal storage materials to store any surplus heat energy generated during the sun's peak hours. This creative method not only helps the environment by reducing our dependence on traditional energy sources, but it also offers a long-term solution for keeping food warm. The goal of this project is to provide a green, efficient, and cost-effective way to heat meals when traditional energy sources are unavailable. Solar tiffin warmers with thermal storage could help people in off-grid locations live better lives while also decreasing their environmental impact and boosting sustainability.

Introduction Keeping home-cooked meals warm and fresh during transit is a constant issue in today's fast-paced world, when individuals are often on the move [1-3]. In every household, cooking plays a significant role. Animal manure and firewood are major sources of cooking energy in rural India, where almost 70% of the population resides [4-7]. Even while they work well for storing food, traditional tiffin carriers don't always manage to keep it at the right temperature for long periods of time. This is particularly true in areas where power isn't always consistent. The solar tiffin warmer with thermal storage is a new idea that this study presents to solve this problem [8–11]. A small and portable tiffin warmer with thermal storage capabilities may be powered by solar energy and kept heated for hours using this revolutionary device. An effective and ecological approach for retaining food temperature during transit has been proposed, which blends sophisticated technologies including solar radiation and phase change material (PCM) [12]. An efficient method to offer a consistent supply of solar heat is to incorporate a thermal storage. Potential thermal energy storage materials, phase change materials are known for their high latent heat and consent charging/discharging temperature. Using a thermal reservoir to store the sun's abundant energy, this technology provides a sustainable and dependable substitute for traditional tiffin carriers. This introduction sets the stage for exploring the design, functionality and potential applications of the solar tiffin warmer with thermal storage [13]. By conducting this research, we hope to promote sustainability and energy efficiency while simultaneously improving the lives of those who are always on the move.
