EXPERIMENTAL APPROACH TO THE DRYING KINET ICS OF FOOD AGRICULTURAL PRODUCTS - APPLICATION FOR ORANGE PEELS AND BEET PULP

An experimental study of the convective drying of thin layer of two fo od agricultural products (oranges peels and beet pulp) has been carrie d out with a blower in air controlled conditions. This study has permi tted to determined the reactions of these products under different dry ing conditions and to establish the empirical correlations giving the drying rate for each product. The sorption isotherms of these products have been obtained experimentally by equilibrium method with sulfuric acid solutions or with saturated salt solutions.
