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...

A dynamic kiln-wide wood drying model was developed previously to solve the integral form of the unsteady-state mass, momentum and energy balance equations in the air side. For the wood side, an empirical model, characteristic drying curve, for the internal moisture movement is used, which was obtained for low and medium temperature drying of Pinus radiata, with a medium velocity of 1.44.1 m s....

HE limitation in the penetrating power of electrons is one of the most T serious obstacles in the study of chromosomes by electron microscopy. Chromosomes are generally larger than 0.2p in diameter and are nearly opaque to electron penetration. At various stages of the nuclear cycle, however, chromosomes change their size and shape. Dividing chromosomes are generally largest and “resting” chrom...

In this paper, the results of an experimental study on textile thermal drying after wet processing pretreatments are presented. The mass variation of the studied samples as a function of drying time was determined using the gravimetric method at three different temperatures: 100°C, 110°C and 120°C. A polynomial model was found and established to follow the drying phenomenon of wet textile fabri...

Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrared lamps were also pla...

Supercritical carbon dioxide has replaced many liquid organic solvents in industry due to its tunable solvent properties, environmental friendliness, and easily achievable critical parameters. The unique properties of supercritical fluids in general, such as gas-like diffusivity and zero surface tension, make them particularly applicable to the field of conservation. This presentation reports o...

A forced convection solar drier is designed with evacuated tube collector and a blower. The performance of the designed drier is evaluated by carrying drying experiments at Thanjavur District, Tamilnadu, India with amla. Solar drying of amla is carried at different air velocity flow rates – 4m/s, 4.25m/s and 4.5m/s and is compared with natural sun drying. The temperature of the drying chamber r...
