DRYING KINETICS STUDY OF PARBOILED RICE BY USING ARTIFICIAL NEURAL NETWORK MODEL
The objective of this research was to predict hot air, infrared radiation and hybrid hot air-infrared radiation drying kinetics of leb nok pattani parboiled rice using an mathematical model and an artificial neural network model.Drying kinetics of parboiled rice was investigated considering different drying conditions.The drying experiments were performed at five levels of drying air temperatures of 60–110℃, two levels of infrared intensity of 5,118 and 7,678 w/m2, air velocity was fixed at 1 ± 0.2 m/s.Ten different mathematical models available in the literature were fitted to the experimental data.Among the considered mathematical drying models, page model, was found to be more suitable for predicting drying of parboiled rice.In addition, a feed-forward artificial neural network was employed to determine the relationship between the moisture ratio of the material to be dried and the input parameters of the drying air temperature and infrared intensity.A selected neural network structure was used for studying the influence of transfer function, different feed-forward propagation training algorithms and the number of hidden neurones.The results between mathematical model and artificial neural network model were compared with the experimental data.In this research, it was obviously found that the prediction results of feed-forward levenberg-maqurdt’s propagation are good agreement with experimental results than others.Thus, it was concluded that the artificial neural network could be effective for modelling of the grain drying process.
