On the Analysis of Drying Process

Kinetics of spouted-bed drying of barley: Diffusivities for sphere and ellipsoid

“…Igathinathane and Chattopadhyay (1999) and Hacihafizoglu et al (2008) applied geometry of oblate spheroid to derive moisture diffusivity of rough rice. Despite this, most of the moisture diffusivity data described in the literature have been derived using the technique of curve fitting to the experimental data under the assumption of the spherical shape of a single kernel and that moisture diffusivity of grain does not depend on its moisture content and temperature (Kundu et al, 2005).…”

Post-harvest technology of pulses

“…There are different methods of artificial drying with hot air such as fixed/movingbed drying, fluidized-bed drying, spouted-bed drying, thin-layer drying, etc. (Kundu et al, 2005). General food grain dryers can also be used for drying of pulses.…”

“…The equilibrium moisture content is the final moisture content of the grain at a certain temperature and relative humidity. The important factors influencing drying of grains are temperature and moisture content of the grain and, to some extent, relative humidity and air velocity (Kundu et al, 2005).…”

“…Statistical models can be developed by using an appropriate equilibrium moisture content based on a multiple regression method for constant drying rate as a function of drying air temperature (Kundu et al, 2005) using the Arrhenius relationship. Knowledge of the drying kinetics of biological materials under various process conditions is extremely important for both the design of dryers and modeling of drying processes (Mathioulakis et al, 1998;Xia and Sun, 2002;Barrozo et al, 2004).…”

Modeling Equilibrium Moisture Content of γ-Ray Irradiated Rough Rice

“…These models are still widely used in latest studies of drying technologies. [3][4][5] For a specified rice variety, EMC depends mainly on the relative humidity and temperature conditions of the environment. [6,7] The values of EMC decrease with increasing temperature at the same relative humidity and increase with increasing relative humidity at the same temperature.…”
