DRYING KINETICS AND MATHEMATICAL MODELING OF FAR-INFRA RED VACUUM DRYING OF SOME VEGETABLES AND FRUITS

Abstract

In this paper the drying kinetics of far-infrared vacuum drying of some vegetables and fruits are presented. The experimental data of drying kinetics were obtained on experimental drying setup designed to imitate industrial dryer. Two well-known thin layer drying models from scientific literature were used to approximate the experimental data of drying kinetics in terms of moisture ratio. The performed statistical analysis shows that the model of Aghbashlo gives the best results for approximation of experimental drying data.
