AbstractThe performance of a mixed mode solar banana dryer consisting of a drying cabinet covered by 12 m2 of transparent glass and 31.7 m2 of flat plate solar air heater was evaluated. In operation, warm air was drawn by a fan from the solar collector and was blown through a heat exchanger before entering the drying cabinet where solar radiation was absorbed by the drying product. -- Experimental results showed that the first law efficiency of the solar dryer increased linearly with the mean moisture content of bananas and decreased linearly with the specific air flow rate (the ratio of mass flow rate of air to the dry mass of bananas). The maximum efficiency was about 30%. Drying time was 6 days for continuous drying. From the financial analysis, it was found that pay-back period varied form 1.5-5.4 years when the difference in price between direct sun drying and cabinet drying varied form US$ 0.28-US$ 0.08 per kilogram of bananas.
