FOOD SYSTEM MODEL DRYING:TEMPERATURE AND MOISTURE PROFILES

摘要：

　　This work consists in mathematical modeling,by forced convection,of drying on food models,considering mass and heat transfers,shrinkage and variable transport coefficients.Using spherical coordinates,mathematical representations were developed to simulate temperature and moisture profiles,being the equations of the model based on Fick and Fourier Laws.Spatial derivatives were approximated by Finite Difference Method and the resulted equation system was solved using Runge Kuttas method.Matlab was used for numerical solution and simulation.The mathematical model,that includes the global Biot number,had a good adjustment to the experimental results,simulating radial temperature and moisture profiles.
