Vacuum Drying Characteristics of Some Vegetables
In this research the drying of four kinds of vegetables was investigated in a vacuum dryer. The effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °C) was studied. Six thin-layer drying models were fitted to drying data and suitable model was selected from them. Then effective moisture diffusivity and ...
متن کاملModeling of Vacuum Drying of Licorice (Glycyrrhizia glabra) Roots
Background and Objectives: Desiccation is a necessary procedure to eliminate moisture from foodstuffs in industries, especially pharmaceutical, food and tobacco industries. In the present study, a mathematical modeling was assessed for vacuum drying of the licorice roots. Materials and Methods: Fresh licorice roots were dried at 50 mbar. Temperatures included 22to 150°C and diameters of roots ...

15 صفحه اولVacuum Drying Characteristics of Salicornia herbacea L
Vacuum drying of Salicornia herbacea L. was performed at different drying temperatures (50, 60, 70, and 80°C) to evaluate the drying characteristics and the effect of drying temperatures on the quality of Salicornia. As the drying temperature increased, the drying time decreased significantly (P< 0.05). The drying rate decreased with decrease in moisture content and increase in drying time. On ...
