The present work deals with a study on the physical characteristics of stoichiometric hydroxyapatite microspheres produced by spray-drying process through different operating conditions. Obtained are intended to be used as powder feedstock in bed selective laser processing additive manufacturing technologies where flowability and particle size distribution special importance. powders at paramet...

The objective of this work was to evaluate the influence of inlet air temperature and emulsion composition (total solid content and oil concentration), as well as its associated properties (viscosity and droplet size), on the microencapsulation of flaxseed oil by spray drying, using gum Arabic as wall material. Coarse emulsions were prepared by blending the flaxseed oil and the gum Arabic solut...

This study evaluated the chemical properties (polyphenol and genistein contents) of soybean extracts obtained by biotransformation and dried by spray dryer at different conditions and their in vivo ability to inhibit 12-O-tetradecanoylphorbol-13-acetate- (TPA-) induced biochemical alterations in the skin of hairless mice. By comparing the obtained data with that of the well-known active soybean...

Abstract A solar drum dryer was designed and constructed for paddy drying, including a fixed outer inner perforated drum, which rotated at the desired rotational speed inside drum. The maximum capacity of 10 000 g. controlled. thermal energy required provided by absorber plate. performance examined three levels (0.21, 0.42 0.84 r.p.m.), slope (1°, 1.5° 2°) air velocity (1.7, 1.8 1.9 m.s−1). dia...

-A stochastic model based on the Boltzmann kinetic equation and employing the comprehensive treatment of the dynamics of binary droplet collisions is suggested to describe the droplet size and spatial distribution in dense spray. The model is valid for highly non-equilibrium impinging sprays in which the inertia of the droplets is very high and dynamic coupling with the gas is low. A Monte Carl...

Diabetes is considered one of the main threats to global public health in this era. It is increasing rapidly in every part of the world; the prevalence of the disease will grow to the point where 366 million people will be affected by 2030. The prevalence of diabetes mellitus (DM) in the Saudi population is high, and the majority of patients suffer from type 2 DM. Marketed oral antidiabetic dru...
