Energy consumption performance evaluation of an industrial grain dryer is an essential step to check its current status and to put forward suggestions for more effective operation. The present work proposed a combined IRCC dryer with drying capacity of 4.2 t/h that uses a novel drying technology. Moreover, the existing energy–exergy methodology was applied to evaluate the performance of the dryer on the basis of energy efficiency, heat loss characteristics, energy recovery, exergy flow and exegetic efficiency. The results demonstrated that the average drying rate of the present drying system was 1.1 gwater/gwet matter h. The energy efficiency of the whole drying system varied from 2.16% to 35.21% during the drying process. The overall recovered radiant energy and the average radiant exergy rate were 674,339.3 kJ and 3.54 kW, respectively. However, the average heat-loss rate of 3145.26 MJ/h indicated that measures should be put in place to improve its performance. Concerning the exergy aspect, the average exergy rate for dehydration was 462 kW and the exergy efficiency of the whole drying system ranged from 5.16% to 38.21%. Additionally, the exergy analysis of the components indicated that the combustion chamber should be primarily optimized among the whole drying system. The main conclusions of the present work may provide theoretical basis for the optimum design of the industrial drying process from the viewpoint of energetics.

In this research, a comprehensive thermodynamic investigation through energy and exergy analyses is conducted to assess the performance of malt and mixtures of malt - inert add drying process. In this regard, energy and exergy efficiencies are evaluated with the experimental thermodynamic data for different techniques of malt drying (fixed, fluidized and modified fluidized bed with inert add). For all drying techniques analyzed, the study evidenced that energy utilization increases with drying agent velocity, drying time and temperature, meanwhile the energy utilization ratio decreases with this parameters. On the other hand, exergy loss and exergy efficiency increases with air velocity and drying temperature, but they have an antagonist behavior regarding with drying time: exergy loss decreasing in time, meanwhile the exergetic efficiency increases in time. The energetic values of the parameters for the fluidized bed are considerable smaller than those of fixed bed, which recommends the fluidization as intensification technique for malt drying. Also, the study evidenced the good influence on the energetic behavior of the fluidized bed, if the malt particle are mixed with a porous, hygroscopic inert add.
