The present work is developed as a response to the priority needs for small local farm crops that are not financially supported by government royalties, in a tropical country located in South America. The solar dehydrator described here is a modular unit to be used in non electrically interconnected zones (NIZ), and built with local materials, that makes use of convective heat to remove the moisture of previously sliced farm products. This way, this study covers the development of a simple agroindustrial process focused on the upgrading
