Resumo: | The Brazilian Northeast stands out, among other things, for its fruit production and the availability of solar energy. However, the production of dried fruit in this region of the country is still not expressive. Studies on food drying have been developed around the world, since the traditional drying process in an oven requires large investments and high electricity consumption, increasing the cost of the final product. Solar drying in equipment built with low-cost materials and whose operation and maintenance can be performed without the need for highly complex actions, becomes an appropriate technology for family farming. The objective of this work was to compare the performance of an indirect exposure solar dryer in different climates and meteorological conditions. For that, experimental drying tests were carried out, in the drying of silver bananas, in the cities of Campina Grande, PB and Pombal, PB, in periods of greater and lesser intensity of solar radiation. It was possible to observe the influence of the temperature and relative humidity conditions of the ambient air and the incidence of solar radiation on the drying time. Average thermal yield of 30,04% and average drying time of 13,5 hours were obtained, results similar to those reported in the literature. |

Sin embargo, la producción de frutos secos en esta región del país aún no es expresiva. Se han desarrollado estudios sobre el secado de alimentos en todo el mundo, ya que el proceso tradicional de secado en horno requiere grandes inversiones y un alto consumo eléctrico, aumentando el costo del producto final. El secado solar en equipos construidos con materiales de bajo costo y cuya operación y mantenimiento se puede realizar sin necesidad de acciones de alta complejidad, se convierte en una tecnología apropiada para la agricultura familiar. El objetivo de este trabajo fue comparar el desempeño de un secador solar de exposición indirecta en diferentes climas y condiciones meteorológicas. Para ello, se realizaron pruebas experimentales de secado, en el secado de banano plateado, en las ciudades de Campina Grande, PB y Pombal, PB, en períodos de mayor y menor intensidad de radiación solar. Se pudo observar la influencia de las condiciones de temperatura y humedad relativa del aire ambiente y la incidencia de la radiación solar en el tiempo de secado. Se obtuvieron rendimiento térmico promedio de 30,04% y tiempo de secado promedio de 13,5 horas, resultados similares a los reportados en la literatura.O Nordeste brasileiro destaca-se, entre outros aspectos, pela produção de frutas e pela disponibilidade de energia solar.
