Physical Properties of Green Pea in an Inert Medium FBD Dryer Assisted by IR Heating
The drying behavior of green peas is investigated in a pilot scaled Fluidized Bed Dryer (FBD) with inert particles assisted by an Infra Red (IR) heat source. The variation of shrinkage and moisture diffusivity with temperature and moisture content were investigated. The experimental drying curves were adjusted to the diffusion model of Fick’s law for spherical particles. The result was that...
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 کاملmodeling apparent density of potato strips pretreated with ultrasound and drying during deep-fat frying
the aim of this study was to investigate the effect of ultrasound and drying pretreatments on apparent density as well as modeling apparent density during deep-fat frying of potato slices. ultrasound pretreatment was performed at 28 and 40 khz for 15 min and drying pretreatment were conducted at 80°c for 8 and 15 min. then, the frying process was done at 150, 170 and 190°c for 60, 120, 180 and ...
متن کاملmodeling apparent density during drying of grapes pretreated with ultrasound and carboxymethyl cellulose
drying foodstuffs can have negative effects on quantitative and qualitative characteristics of the products, including porosity and bulk density. therefore, novel technologies can be used to improve these characteristics. in this study, apparent density changes during drying grapes pretreated with ultrasound for 10, 20 and 30 minutes, and carboxymethyl cellulose (cmc) at three concentrations of...
