Design and fabrication of solar dryer A Review

The Solar Dryer project demonstrates a simple, low-cost, and eco-friendly solution for drying agricultural products using renewable solar energy. The cabinet-type design with brown outer plywood surface and black inner coating improved heat absorption and insulation.  The integration of a 12V solar panel, battery, and charge    controller ensured independent operation without grid electricity. The inclusion of a DC fan enhanced airflow, resulting in faster and more uniform drying compared to natural sun drying methods.  The system successfully achieved the main objectives: Utilization of renewable energy Reduction in drying time Hygienic drying environment Portable and user-friendly design Low operational cost  This project proves that small-scale solar dryers can effectively reduce post-harvest losses and support rural farmers. The design is simple enough to be replicated and commercially developed for small food processing units. Overall, the developed Solar Dryer is efficient, economical, environmentally friendly, and suitable for small-scale agricultural use.
