Verma, R.C. | Prasad, S.
Moisture diffusion during soaking of Kisan maize in water at temperatures ranging from 30 to 90 degrees C was studied. The soaking data were fitted in Becker's model to determine the moisture diffusivity. The moisture diffusivity was found to vary from 3.994x l0(-8) to 40.967x10(-8) m2/h. The energy of activation of maize was found to be 35069.55 kJ/kg mol K. The relationship between moisture diffusivity and reciprocal of absolute temperature followed the Arrhenius equation as D = 0.040107 e-4217.96/Tw. A mathematical model for prediction of moisture content in maize with time, during hot water soaking was developed for known initial moisture content and water temperature as (...).
