| Abstract | Thin layer rewetting equations were developed for rough
rice. Experiments we re carried out under dynamic conditions at
d:ifferent combinations of air temperature-relative humidity-grain
initial moisture content. Temperatures ranged from 30°C to 45°C,
while the relative humilities ranged from 70 % to 95 %. The
initial moisture contents of the grain varied from 9% wb to 15%
wb. Various models were fitted to the experimental data and the
best fitting model was selected. Modified exponential model,
also cal1eel as Page is model Wf.IR found as the best to fit the
overall range of data .
A computer simulation program was developed to simulate the
grain rewetting, after adding the rewetting equation to the~
program. The simulation estimated the the moisture profile in a
bed of rough rice reasonably well . The estimated values werc3
found to be well within the practical range.
Another approach of direct estimation of moisture profile
from the rewetting equation was tried and found to be equally
well, if not better, than the computer simulation. Added
advantage with this method is the considerable saving of time as
it does not have to go through the iterative process like the
computer simulation. |
