Construction of a Solar Seed Dryer

Abstract

Solar thermal systems have shown to be practical, economical, and environmentally benign when used for the preservation of agricultural goods such as fruits, vegetables, coffee, and other commodities. By drying crops and food using solar heating systems, we can improve product quality, reduce waste, and use conventional fuels less often, all of which contribute to a higher standard of living. Unfortunately, many nations that may benefit greatly from solar food processing technologies do not have enough access to trustworthy information. A solar dryer for drying maize seeds is the primary subject of this research. The solar seed drier took practicality, cost, and accessibility of materials into account throughout its design process. sun seeds dryers typically include an absorber plate, a transparent cover (glass), a drying chamber, and a sun collector. Measurements of 1000 mm x 1000 mm (1 m²) make up the solar seed drier's cross-section. The dimensions of the box's front were trimmed to a length of 1000 mm and a height of 320 mm. A 30 mm tall and 600 mm long vent was cut into the front. The solar seed drier's performance was evaluated, and it was found that in the no-load test, the heated air within the dryer was consistently hotter than the surrounding air. During the three days, a considerable quantity of moisture was removed. However, it was at its highest on day one and at its lowest on day two.
