Abstract :

A solar cassava dryer with subsidiary heating source has been designed, constructed and tested. The performance was evaluated as follows: using a load of 60kg, the average efficiency is 41.74% for solar with subsidiary heating and 25.77% for solar drying respectively; using a load of 50kg the solar with subsidiary heating source has an average efficiency of 35.79%, and 29.35% for solar drying. The average drying rates using 60kg load is 2.01x10-3kg/s, 1.56x10-3kg/s and 1.09x10-3kg/s for both solar with subsidiary heating solar drying and open air drying respectively; using 50kg load the average drying rates are 1.44x10-3kg/s, 0.89x10-3kg/s and 0.54x10-3kg/s for solar with subsidiary heating solar drying and open air drying respectively. The results shows that the method of drying using solar with a subsidiary heating had a higher drying rate with higher efficiency, higher initial moisture loss, higher temperatures and less drying time.
