The effect of proportion of maltodextrin and gum arabic as carrier material and the percentage of nutmeg essential oil as flavor load on microencapsulation by spray drying was studied. The proportions of 0, 20, 40 and 60 percent gum arabic (w/w) in the carrier blend and 10, 20 and 30 percent nutmeg oil (w/w) as flavor load were studied. Emulsions were microencapsulated in a vertical co-current ...

The effect of proportion of maltodextrin and gum arabic as carrier material and the percentage of nutmeg oleoresin as flavor load on microencapsulation by spray drying was studied. The proportions of 0, 20, 40 and 60 percent gum arabic (w/w) in the carrier blend and 10, 20 and 30 percent nutmeg oleoresin (w/w) as flavor load were studied. Emulsions were microencapsulated in a vertical co-curren...

Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...

A wheelchair with omni-directional wheel is introduced in this article. Two kinds of omni-directional wheel, Mecanum wheel and Trans wheel, are illustrated and their motion principles were analyzed. Virtual Reality Modeling Language (VRML) is adopted to implement the real-time customization and motion simulation. In the realtime customization process, the color of some parts of the wheelchair c...

the performance of the electric submersible pump (esp) significantly affected by gas void fraction (gvf). thus, using of a rotary gas separator (rgs) is a suitable solution for this issue. the performance of the rgs is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and gvf. in this study, the influences of gvf, viscosity, and ...
