This study is an extension of the previous work done with ARS-680
Environmental Chamber. Drying is a complex operation that demands much energy
and time. Drying is essentially important for preservation of ginger rhizome.
Drying of ginger was modeled, and then the effective diffusion coefficient and
activation energy were determined. For this purpose, the experiments were done at six levels of varied
temperatures: 10°C, 20°C, 30°C, 40°C, 50°C and 60°C. The values of effective
diffusion coefficients obtained in this work for the variously treated ginger
rhizomes closely agreed with the average effective diffusion coefficients of
other notable authors who determined the drying kinetics and convective heat
transfer coefficients of ginger slices.
