Analysis of a Solar Dryer Box with Ray Tracing

A growing preservation technique in western part of Nigeria is the use of solar dryer box. Conventionally, exposure to direct sun light has been the practice to preserving farm produce because majority of the farmers cannot afford advanced techniques that may depend on electricity supply from the national grid. Recent studies have shown that alternatives to direct exposure to the sun are preferable for vitamin preservation. A simulation of a solar box design for such purpose is presented for temperature distribution based on sun direct solar irradiation of 1423W/m 2 of Akure (5.304o Latitude 7.258o Longitude). Results compare well with experiment.
