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. The drying rate data was generated
and the high rate of 2.0g/hr was used afterwards to design and fabricate the
corn-on-cob dryer. From the results, drying of a sample of maize corn-on-cob
by the laboratory dryer took a period of three days and six hours to reach the
15% moisture content (wet basis) needed. A test run was carried out on the
fabricated dryer and seventeen hours was used to dry a sample of maize corn-
on-cob to the same 15% moisture content. This implies that design data is
satisfactory as its application in the fabrication of the dryer resulted in an
increased flow rate of air in the dryer thereby increasing the rate of drying at the
same drying temperature of 40oC.
