2. Modeling and simulation the malt bed as a porous medium raises a
number of problems in terms of heat flow (hot air) through it, the more so as
malt drying involves both heat transfer and mass transfer.
3. The complexity of the mathematical model is high and the CFD
simulation was not possible, or would have taken more time without the support
graphics station of high performance.
4. The temperature profile in malt bed resulting from the CFD simulation
are presented with a high degree of accuracy since the previous simulations
were performed its calibration data obtained from experiment. The input air
temperature in the dryer were obtained experimental and functions by
temperature and time are considered as initial date in simulation.
Both experimental and simulation were unstady preformed on a 3D geometry
dryer.
5. Temperature distribution in the bed malt is very useful in futher
development of the mathematical model by introducing mass transfer depends
on the time evolution of temperature.
6. The stand designed for drying allows large variations of temperature
and humidity of hot air inlet, fitted with sensors for temperature and humidity as
well as air parameters variation.
7. The proposed model and CFD simulation can be used for drying other
grains.
