| Abstract: | According to experimental data and theoretical analysis, an empirical model to describe the mass transfer of convecitive drying of dahurian larch has been setup.The drying constant which is related to four main process variates is included in this model.And the mathematical relationship among them is also determined. Experiments have proved the precision of the model.And it is found in research that the air temperature. the relative humidity,and the test piece thickness all have a grater effect on the drying rates. |
