Evaluation Of Page Model On Drying Kinetics Of Red Chillies
Subject area: Agriculture and Veterinary Sciences · Area of research: Agriculture
Abstract
The thin layer drying kinetics of chillies (Capsicum annuum L) at different layers were experimentally investigated in a natural convective solar dryer with layer thicknesses of 1cm, 2cm and 3cm. The chillies were dried from an initial moisture content of about 81. 23% (w.b) to a moisture content of 7. 13% (w.b) and the moisture content of chillies were determined at 3 hours interval. The drying data were fitted with Page model. The values of the drying constants for the model was determined. The performance of the model was investigated by comparing the correlation coefficient (r), chi-square and root mean square error (RMSE) between the observed and predicted moisture ratios. The effects of layer thickness of chillies on the drying characteristics and drying time of drying process were evaluated. The results have shown that an increase in the drying layer thickness causes longer drying times. According to the results, Page model was found to be suitable for drying chillies with 1 cm layer thickness. The model satisfactorily described the drying curve of chillies with correlation coefficient of 0.814 and 0.022 and 0.132 for chi square and RMSE respectively
