摘要：Drying behavior of furfural residues was studied in a laboratory type dryer. The effect of drying temperature, initial material load, particles size and heating rate on the drying characteristics of furfural residue was investigated. The results show that the increase in drying temperature resulted in a decrease in the drying time, the drying rate increases with the decrease of moisture content. The optimum drying temperature may be 130 degrees C. Higher initial material load induced longer drying time, and the moisture content decreases gradually. Constant drying rate period was not found in all runs. The drying rate of larger particle size is lower than that of small size, and the maximum drying rate occurred with furfural residues of 20 mesh. The drying rate of rapid heating rate is greater than the slow one as the moisture content below 48.2%. The experimental drying results of furfural residues obtained were fitted to several models. The accuracy of the models was estimated with the root mean square error analysis (RMSE), sum of squared errors (SSE), correlation coefficients (R-2) and reduced chi-square (chi(2)). The results of Page model were better than other models. The parameters of page model were estimated with multiple regression analysis.
