Study on Drying Kinetics of Fermented Corn Grains

Ajala A.S., Ajala F.A., Tunde-Akintunde T.Y.


Corn grains were fermented for three days and later drained and dried at 600C, 650C and 700C in a convective hot air dryer. Kinetics of drying was investigated using Fick’s second law. Drying pattern was observed to be in the falling rate period. Non linear regression analysis software (SPSS), was used to fit in the experimental data and the coefficient of determination was found to be greater than 0.90 for all the models except Midilli. The values of R2, RMSE, MBE and reduced chi square showed that Logarithm model best described the drying behaviour of the samples.
