Sažetak
Th is paper presents a mathematical model describing convective drying of corn kernels of different hybrids. The convective drying process was examined at four air temperatures (70, 90, 110 and 130º ; C) using hybrids ‘ Bc 462’ , ‘ Bc 4982’ , ‘ Bc Jumbo 48’ , ‘ Florencia’ and ‘ Stefania’ The drying process was able to be described by a model based on exponential equations. Activation energy necessary for the onset of the drying process, namely water activation in kernel, was determined using the Arrhenius equation. Results show that activation energy is in the ranges from 10.39 kJ/mol (hybrid Bc Jumbo 48) to 15.56 kJ/mol (hybrid Stefania). Data and analysis together indicate that the increase in energy necessary to induce the water release process from corn kernel is proportional to the increase in the activation energy of drying.
