Description

The objective of this study was to describes the development of a three-dimensional (3-D) mathematical model, which was used to during drying of germinated parboiled Thunya-sirin glutinous rice product under dryer. The three-dimensional mathematical models were solved numerically using the finite element method; additionally the mathematical model was validated by comparing the simulated results with the experimental. In this study, the following drying parameters were set for investigation: Far infrared intensities at 3 to 5 kW/m^2 were combined with a 40oC temperature and 1 m/s air velocity. The results showed that the mathematical model can be satisfied to predict the evolutions of germinated parboiled Thunya-sirin glutinous rice product. An increase of the applied intensity from 3 kW/m^2 to 5 kW/m^2 resulted in the shorter drying time and the reduced energy consumption by 70 min and 5.29 kWh/kg water removed, respectively. The average effective moisture diffusivities of the germinated parboiled rice were in the ranges 1.25 x10^10 – 3.48x10^10 m^2/s.
