Shrinkage of papaya (Carica papaya L.) during convective drying: Influence of glass transition phenomenon
The aim of the present work was to study the shrinkage phenomenon during convective drying of papaya cubes and relate its extension with glass transition. A convective tray dryer was used for the experiments, which were carried out at air temperatures of 40 and 70°C and air velocity of 1.0m/s. The shrinkage behaviour was accomplished by total area and apparent volume alterations along drying. S...
متن کاملSimulation Shrinkage and Stress Generated During Convective Drying of Carrot Slices
The moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. The aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. The effect of shrinkage on the heat and mass transfer profiles were considered. Non-constant physical and thermal properties were also incorporated in the model and th...

متن کاملa study of the shrinkage changes and mathematical modeling of garlic (allium sativuml.) during convective drying
garlic (allium sativuml.) is one of the most important allium spice. from an economic point of view, the dried garlic slices are valuable products. in this research, garlic slices as a thin layer were dried in a laboratory scale hot-air dryer, under air flow of 1.5 m/s, air temperatures of 50, 60 and 70˚c and slice thicknesses of 2, 3 and 4 mm. the mean values of shrinkage of garlic slices obta...
