Abstract: The main objective pursued in this paper is to investigate the
single layer drying behavior of fish slices experimentally in an
electrohydrodynamic (EHD) dryer and also to perform mathematical modeling.
Drying experiments of fish slices were studied at 10, 15, 20, 25 and
30°C, relative humidity of 30%, 40%, 50%,
60% and 70%, drying voltage from 5 kV to a maximum voltage of 50 kV in
increments of 5 kV, the moisture content of fish slice for constant sample
thickness (8 mm), and the samples thicknesses from 2 mm to a maximum 16 mm in
increments of 2 mm in a EHD dryer. Sample weight, drying rate were measured
during drying and drying rate curves were obtained for each experimental data.
The drying rate data were performed using seven different mathematical models
to estimate a suitable model according to their correlation coefficient (R),
determination coefficient (R^{2}) and standard error (S),
which were predicted by linear and non-linear regression analysis using SPSS
computer program. It was deduced that the quadratic model were found to
satisfactorily describe the drying rate of fish with the drying voltage,
ambient temperature and drying time, respectively. However, the exponential
model was the most suitable model to describe the drying rate of fish with the
relative humidity, the moisture content and the thickness of fish slices,
respectively.
