In this work, an analytical solution of a mass transfer equation for drying considering both
shrinkage and variable diffusivity was proposed. Experimental drying kinetics for mango …

Hot air drying is an energy intensive process and can affect bioactive components. A
common method of food drying is in a fixed bed. The application of high-intensity ultrasound …

Theoretical moisture and temperature evolution during cacao fixed bed drying were
estimated with non-steady heat and mass transfer equation both in particle and bed. The …

This study evaluated drying barley in a fixed bed dryer either reversing the airflow every 10
min or with a conventional airflow input, with no reversal, and investigated the moisture …

The global behaviour of a deep bed dyer is studied. The system is considered as a porous
media at the macroscopic scale. A model based on heat and mass balance is applied to the …

A heat and mass transfer model in prolate spheroidal coordinates system was proposed to
describe the drying of green coffee beans. The model describes the 3D moisture and …

A simple combined model involving semi-infinite slab geometry with Fickian diffusion and
the Harkin-Jura adsorption isotherm, adjusted to the final equilibrium experimental moisture …

A mathematical model based on the heat and mass transfer mechanisms between the air
and the product was developed in order to simulate the fixed bed drying process of foods …

Habanero pepper (Capsicum chinense) is a source of phytochemicals or bioactive
compounds that have shown benefits in human health. For phytochemicals extraction …

Most dryer design programs or dryer simulators use “thin layer equations” to predict mass
transfer rates in each subdivision of grain beds in dryers. These equations work well under …
