Abstract
Fruit drying is a very important process that has as one of its main objectives to avoid waste, helping to preserve quality and increase their storage time. Traditional drying methods such as using kilns can be expensive and using alternative methods such as using a solar dryer is a more sustainable and affordable alternative. Thus, in the present work an indirect exposure solar fruit dryer was developed and tested in the drying of bananas. The dryer was built with low-cost materials, such as wood, zinc, expanded polystyrene, alveolar polycarbonate and reused metals. The development of the dryer had the differential of providing an increase in the temperature of the drying air in the solar collector, by passing it through a metal pipe to the oven. The drying of the bananas in the lasted 8 hours and the drying parameters obtained indicate the viability of the technique used, considering the drying efficiency values of more than 80% and the humidity values on a wet basis close to those recommended by ANVISA. At the end of the research, it was verified that the fruits were successfully preserved and it can be considered that the use of such techniques will contribute to the profitability of small-scale farmers/rural producers
