Abstract:Pleurotus eryngii slices were dried as thin-layers with thickness of 2 mm and 4 mm in the ranges of 70℃-90℃of drying hot-air temperature in a convective dryer.The effect of drying hot-air temperature and slice thickness on the drying characteristics was analyzed.Resultsindicated that drying took place in the falling rate period.Moisture transfer from Pleurotus eryngii slices was described by applying the Fick'sdiffusion model. A non-linear regression procedure was used to fit eight thin-layer drying models available in the literature to the experimental moisture loss data.The mathematical models comparedaccording to the three statistical parameters such as the coefficient of determination（R2），reduced chi-square（Χ2）and root means squareerror（RMSE）between the observed and predicted moisture ratios.In conclusion，the Pagemodel satisfactorilydescribed the drying characteristics of Pleurotus eryngii slices.
