Drying of licorice root by novel radiative methods

In this study, licorice root was successfully dried using two different radiative dryers (Carbon fiber-assisted cabin drying-CFACD and infrared drying-ID), and their effects on some drying characteristics, quality properties, and energy-exergy efficiency were investigated. Page and Verma models were the best models describing the drying behavior of licorice root for CFACD and ID methods, respectively. ID protected total phenolic content (TPC) better than CFACD while the changes of color properties were higher for ID. Energy and exergy efficiencies of CFACD were 40.20 +/- 0.20% and 31.87 +/- 0.10%, respectively, while these values were 10.39 +/- 0.33% and 9.99 +/- 0.27% for ID, respectively.
