In this study, the influence of air temperature, velocity and humidity on the thin-layer drying of rosehip was investigated. A laboratory air drier was designed and used for drying experiments. The system was operated in an air temperature range of 50-80°C, air velocity range of 1·67-3·10 m s -1 and air absolute humidity range of 0·005-0·08 kg [vapour] kg -1 [dry air]. Six mathematical models available in the literature were fitted to the experimental data. By statistical comparison of the values for the six models, it was concluded that the logarithmic model represents drying characteristics better than the other equations. © 2004 Silsoe Research Institute.
