Experimental characterisation and modelling of thin layer direct solar drying of Amelie and Brooks mangoes

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 10 March 2011brA.O., Dissa , D.J., Bathiebo , H., Desmorieux , O., Coulibaly , J., KoulidiatibrDirect solar drying characteristics of Amelie and Brooks mangoes were experimentally determined using a solar dryer made up of four trays and used under weather conditions of fruit harvest period. Direct solar drying curves were established, fitted using 10 mathematical models and simulated with a direct solar drying model. Effective diffusivity, drying rates and drying efficiency were estimated for each drying day and each variety. Results showed that at least four days were necessary to reach the range of preservation water contents. Drying curves depended on variety and were suitably fitted by “two-term” and “Approximation of diffusion” models (with R2≥0.9888,…br Highlights: ►Direct solar drying of “Amelie” and “Brooks” mangoes was investigated. ►The study was carried out under weather conditions of mango harvest period. ►Direct solar drying curves were established and simulated with a suitable direct solar drying model. ►Water diffusivity, drying rates and drying efficiency were estimated for each drying day. ►Drying curves were well fitted by the solar drying model and “Amelie” was the best variety for direct solar drying.
