abstract = {Bambara groundnuts is an indigenous, underutilized African
legume grown primarily for its seeds which are eaten fresh when semi ripe as
a pulse when dry and mature or ground into a flour. In this study, the experimental
dehydration behavior of two different varieties of of bambara groundnuts, Black
variety (BB) of moisture content 0.88 g g-1 and White variety (WB)
of moisture content 0.90 g g-1 was investigated and the experiments
were carried out under isothermal conditions using convection air-forced dryer
at 50, 60 and 70°C. The drying data were fitted to the different mathematical
models such as Lewis, Henderson and Pabis, Logarithmic and two-term models.
The performance of these models was investigated by comparing the determination
of coefficient (R2), reduced Chi-square (χ2) and
Standard Estimate Error (SEE) between the observed and predicted moisture ratios.
The results obtained showed that the logarithmic and the two term models successfully
described the drying behaviour of the seeds. Generally, the moisture diffusivity
constants derived from the Ficks
law of diffusion increased with increase in temperature according to the Arrhenius
type equation with BB variety exhibiting low values (5.97x10-11 to
8.51x10-11 m2 sec-1) and WB high values (1.44x10-11
to 2.78 x10-10 m2 sec-1).}
