DESIGN AND FABRICATION OF MAIZE CORN-ON-COB TRAY DRYER

This study was carried out to generate a design data, design and fabricate a maize corn-on-cob tray dryer used by maize farmers. Ripped maize corns with husks were bought from the market and preserved to retained its moisture content, dehusked and thereafter, dried to a given percentage moisture content of 15%. This was done by laboratory dryer.
