Title
Experimental determination of effective moisture diffusivities of whole- and cut-rosehips in convective drying
Abstract

Average effective moisture diffusivities for both the whole- and cut-rosehips were obtained during convective drying. The effects of process variables such as air temperature, air velocity and air absolute humidity on effective moisture diffusivity were studied. The average effective moisture diffusivity in rosehip ranged between 1.45 × 10−10 and 10.3 × 10−10 m2/s for whole-rosehip and between 1.44 × 10−9 and 5.13 × 10−9 m2/s for cut-rosehip at the temperatures studied. Activation energies for convective drying were found to be 62 kJ/mol for whole-rosehips and 58 kJ/mol for cut-rosehips.
