“…The shape of the paddy considered during mathematical modelling is mostly spherical [11] and cylindrical [4] . However, it was reported that compared to other simpler-shaped models, ellipsoid closely resembles the geometry of rice [15] . Therefore, in this study, an ellipsoid shape of the paddy was considered to solve the model.…”

“…The advancement form of moisture gradient throughout drying in this research was similar to the work reported by Prakash and Pan. [34] But, the occurrence of maximum moisture gradient in the fluidized bed was significantly shorter. These simulations indicated that the maximum moisture gradient occurred in a very short drying time in the fluidized bed drying for which the moisture content of sample was still high.…”

A study of stress distribution inside a germinated brown rice (GBR) kernel during drying is important to understand the fissure formation of GBR and hence control the drying process in order to improve the quality of GBR. In this study, a finite element method performed in three dimensions in conjunction with the heat and mass balance of the drying system was developed to describe moisture, temperature and stress distributions inside GBR kernels during fluidized bed drying. The modelling was carried out using the couple of heat and mass transfer and validated with the experimental data at 90-150C.The results of moisture and temperature predictions agreed well with the experiments.During drying, tensile stress occurred at the layers close to surface while compressive stress occurred at the inner portion of a kernel. The tensile and compressive stresses increased to the highest value at about 30 s of drying, corresponding to the highest moisture gradient, and then decreased afterwards. The tensile and compressive stresses were higher at a higher drying temperature. These stress prediction results corresponded Downloaded by [New York University] at 01:36 31 July 2015 2 to the experiments which show more severity of GBR fissuring at higher drying temperatures.

The objective of this study was to determine the influence of temperature, air velocity and ultrasound application on the drying kinetics of grape seeds. The drying kinetics were determined at 1.0, 1.5, 2.0 and 3.0 m/s and at 40, 50, 60 and 70ºC. At 1.0 and 1.5 m/s, the experiments were carried out with and without ultrasound application. To establish the influence of the variables on the drying kinetics, the results were modeled by means of both the Peleg and a diffusion model. The activation energy was determined (Arrhenius' equation). For an air velocity of over 1.5 m/s, it was determined that the external resistance to mass transfer was negligible. No influence of ultrasound application was observed, probably due to the fact that grape seeds are very hard and have a low level of porosity.
