Abstract

A Solar dryer has been designed, constructed, and tested to dry casava and raw banana slicedwith 2 mm thickness. The dryer was equipped with a cabinet type collector to amplify heat forthe drying chamber. The collector cover was made in angle and using plastic and transparentglass sheets. The drying chamber was also equipped with an aluminium ventilator to let airflowing from the collector sides to the chamber. Data collection was performed from 9.00 a.m to13.00 p.m with one hour interval for three days. The research results showed that the averagemass of the dried banana and casava resulted when using glass and plastic cover, respectively,were 138.93 gr and 163.26 gr. The average dried masses for banana and casava samples whendried using only plastic cover were 146.13 gr and 173.06 gr. As comparison the dried masses forbanana and cassava resulted using a conventional method were 167.33 gr and 185.23 grrespectively for all of each measurement the masses of wet banana and casava were made thesame is 500 gr.
