Chemical Engineering Science, 2016 Lysine, an important nutrient in dairy formulations, is easily damaged during spray drying. The quality of spray dried dairy powders can be enhanced when lysine loss kinetics are coupled with drying kinetics and computational fluid dynamics of spray ...

The drying kinetics of ginger (Zingiber officiate Roscoe) slices of thickness 2.5 mm and diameter of 25 mm was studied at 40, 45, 50 and 55oC and air flow of 1m/s. Results show that drying proceeded faster at higher than at lower temperatures. Drying took place only in the falling rate period mainly by diffusion.

ABSTRACT The kinetics of sausage drying were described in terms of a rate equation and of the diffusivity for moisture in a sausage. The rate equation developed is: dx/dt = ‐k[(x ‐ c)/x] 2 , where k is the rate constant, t is time, x is percent yield at any time, and c is ...

EFFECT OF DRYING MODE ON DRYING KINETICS OF ONION
Drying Technology, 1998ABSTRACT Onion slices 3 mm thick were dried in different modes. Drying at 60°C by convection was taken as a reference process." reviseddate="It has been shown that increase in air temperature increases the rate of drying. Effective diffusivity increases with increasing temperature, but it is strongly dependent on water content. Energy of activation for

Kinetics of Atmospheric Freeze-drying of Apple
Transport in Porous Media, 2006We present investigations of the effect of Atmospheric Freeze-Drying kinetics on the quality (dehydration rate, shrinkage, color, and antioxidant properties) of apple cubes. The experimental data are compared with the result of convective and vacuum freeze-drying processes, and suitable operating parameters are determined.

Microwave drying kinetics of a clay-plate
Ceramics International, 1995This study presents the development of an exponential model for the description of kinetics in the drying process of a porous material under the condition of dielectric heating. The model describes the changes in moisture content and in the rate of drying related to the duration of the process, as well as the moisture content in the material to be ...

Death kinetics of yeast in spray drying
Biotechnology and Bioengineering, 1974AbstractThe death kinetics of a strain of Saccharomyces cerevisiae were studied in an industrial scale spray drier. In solution studies, the death kinetics of yeast was found to be comparable to pathogen destruction. From the studies in drying of yeast a prediction of a 4 log cycle decrease in viable cells of pathogens could be made for normal ...

DESCRIPTION AND ANALYSIS OF TIMBER DRYING KINETICS
Drying Technology, 1993ABSTRACT In this paper an experimental and semi-analytical technique is described that provides a method of estimating a macroscopic drying kinetics curve and internal moisture content profiles is described. Moisture gradients and the time evolution of these gradients are analysed as a function of the air drying parameters (dry-bulb, wet-bulb ...

In order to predict the rate at which moisture leaves a rough-sawn board, the drying kinetics of the lumber need to be considered. The drying of wood involves the movement of water molecules, either as vapour or liquid (fluids), through a complex biological structure, with changes in phase such as thawing and evaporation.
