The solar drying system utilizes solar energy to heat up air and to dry any food substance loaded, which is beneficial in reducing wastage of agricultural product and helps in preservation of agricultural product. Based on the limitations of the natural sun drying e.g. exposure to direct sunlight, liability to pests and rodents lack of proper monitoring, and the escalated cost of the mechanical dryer, a solar is therefore developed to cater for this limitation. This paper presents the design and construction of solar dryer for potato. The dryer is composed of solar collector (air heater) and a solar drying chamber constraining rack of single trays. The air allowed in through air inlet is heated up in the solar collector and channeled through the drying chamber where it is utilized in drying. The design was based on the geographical location and meteorological data were obtained for proper design specification. The dimensions of the dryer are 71 cm x 35.5 cm x 100 cm (length x width x height). Locally available material were used for the construction, chiefly comprising of wood, glass, aluminum metal sheet, copper rod for collector and tray. The optimum temperature of the dryer is 49.33 OC with a corresponding ambient temperature of 36.5 oC.
