Abstract

The drying mechanism and diffusion coefficient of water in spherical droplets (1.73 - 2.08 mm diameter) of tomato concentrates were successfully interpreted and modelled by using Fick's law. Solids content of the initial concentrate (5-15% w/w), and drying temperature (60-degrees - 100-degrees-C) were varied but the drying air was kept at constant velocity and humidity.
