LOCAL MOISTURE PROFILE TO DRYING OF FOOD MODELS SYSTEMS

摘要：

　　The mathematical modeling of drying,by forced convection,to food systems models,considering shrinkage,was studied.Representations to drying kinetics,assuming the mass effective diffusivity as a function of local moisture were considered.Acceptable fittings were obtained when considered the Biot number overall mass models in which the mass effective diffusivity varied linearly and potentially with moisture.The equation was obtained from Ficks model.The mathematical formulation was discretized by finite difference method and Runge Kutta,being solved with the Matlab? program.Thus,through modeling and simulation,the best representations for moisture profiles could be obtained for the geometry studied.
