ISMAIL, O  y  BEYRIBEY, B. Open-air sun drying in thrace region of greece: the experimental investigation of thyme and mint leaves. Lat. Am. appl. res. [online]. 2013, vol.43, n.2, pp. 137-142. ISSN 1851-8796.

In this work, open-air sun drying of thyme (Thymus Vulgaris) and mint (Mentha Spicata)leaves was investigated. A falling rate period was occurred in drying thyme and mint leaves, starting from the initial moisture content (%73.80 for thyme and %84.70 for mint) to the final moisture content (%7.6 for thyme and %4.85 for mint). Drying times were obtained as 440 for thyme and 420 minutes for mint. L values of fresh and dried herbs were respectively found as 40.25 and 35.70 for thyme and as 44.01 and 33.08 for mint. The effective diffusivities were determined as 2.2571*10^-10 m²s^-1 for thyme and as 1.2768*10^-10 m²s^-1 for mint
