Resumo:
The search for optimized and profitable processes is constant in the industrial sector. The use of a classical approach, based on mass, heat and motion transfers, is usually the option used to perform systems analysis, but in recent years, in addition to usual
concepts, the use of thermodynamic concepts, fluid mechanics and techniques of thermodynamic process optimization are also being used in order to determine optimal
parameters for system operation. This tool has been explored known as Entropy
Generation Rate Minimization (MGE). Its use has shown good optimization results
when applied to reactive and non-reactive systems. The industrial plants that have the
drying process have tried to make it a more profitable operation since this operation
consists of high energy consumption and consequently high operating cost. The work in
question is the application of the MGE methodology in a grain drying system using
rotary dryers. The application resulted in a temperature profile curve with less
pronounced behavior when compared to the usual profile determined from the energy
balance. The profile obtained with the use of MGE may lead to a lower energy cost in
the drying process. Moreover, the use of the method in the design calculations of rotary
dryers in the drying of corn kernels can lead to equipment with more economic
dimensions, with reduced length without interference in the efficiency of the process.
