【摘要】 为了简化计算和便于理论分析,食品物料湿含量平衡的动力学模型往往建立在等温条件下,而食品的实际加工处理过程中湿含量的平衡受到环境相对湿度的影响,等温是相对的.因而提出一种半经验非等温吸附平衡数学表达式,比较理想地预测了实际过程,其计算值与实验值吻合较好.更多还原

【Abstract】 Modeling the kinetics of moisture equilibration for food material is being often considered at the isothermal conditions to simplify calculation and theoretical analysis.However,the equilebration is affected by relative humidity.Isotherms is comparative,about which only few case is reported in the literature.A semi empirical math expression which can predict the actual process successfully is presented,both experimental and calculated data are acceptable.更多还原
