Abstract

A maize-on-cob dryer was designed, fabricated and evaluated at the Agricultural and Biosystems Engineering department, Landmark University, Omu-Aran, Kwara state. The main objective of this research was to utilize maize residues as source of heat for maize drying and ensure continuous availability of maize during off season. The dryer consists of a drying chamber, chimney, five trays, electric motor and fan and corn waste container. The dryer contains five trays; each tray in the maize dryer was loaded with 2 kg of maize cobs and was dried at the interval of an hour with a maize residue consumption rate of 1.5 kg/hr. It was evaluated for 7 hours within 3days to dry maize on cob from the moisture content of 76.80% (wet basis) to 13.32% (wet basis) which is the safe storage moisture content for maize. Results of the evaluation showed that drying temperature was within the range of 42°C - 73°C.
