Abstract

The objective of this research was to study the drying characteristics of powdered agricultural residues. Drying experiments of wheat straw (Triticum aestivum) were conducted at four temperatures of 50, 60, 70, and 80oC by a thermogravimetric analyzer. Drying temperature had a significant effect on the moisture change and drying time. There was no constant drying rate period, but a short rising rate period was evident for all drying process due to increasing temperature of the sample at the beginning of drying. Six mathematical models were selected to describe the drying characteristics of wheat straw. The goodness of fit was evaluated by the coefficient of determination (R2), the reduced chi-square ( c2), and the root mean square error (RMSE). Midilli et al. model was found to be the best for modeling the experimental data. The values of EFFECTIVE MOISTURE DIFFUSIVITY of wheat straw dried at 50, 60, 70, and 80oC were calculated to be 1.13×10-8, 1.48×10-8, 1.66×10-8, and 2.29×10-8 m2 s-1, respectively.
