Research ArticleOpen accessIn the abstractEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,013 accessesView PDFCite
