Hot air drying characteristics and kinetic model of Boletus edulis
摘要
Abstract
In order to explore the hot air drying characteristics of Boletus edulis,different hot air temperatures(50,60,70℃)were selected to study the drying characteristic curves and internal moisture transport.The results showed that the hot air drying process of Boletus edulis consists of an increasing rate stage followed by a decreasing rate stage,and raising the temperature significantly shortened the drying time.Six thin-layer drying models were compared,with the Page and Weibull models identified as the optimal models for describing the drying kinetics(R2＞0.998,smallest χ2).Based on Fick's second law,the effective moisture diffusivity was calculated to range from 1.2159×10-10 to 2.0264×10-10 m2/s,increasing with temperature.The activation energy for the drying process,determined using the Arrhenius equation,was 23.57 kJ/mol.This study provides a reference for the industrial hot air-drying processing of Boletus edulis.关键词
