The influence of pretreatment methods like physical, chemical, combined and hybrid treatments on the Turkey berry (Solanum torvum) fruits to enhance water diffusion during drying was assessed due removing a waxy layer peel. Pretreated untreated samples were dried at 70 ?C 4 m/s air flow in fluidized bed dryer. Fruits pretreated with abrasion blanching have lowest time good vitamin C content ret...

Sago is an essential source of starch for some regions in the third and developing world. However, sago processing industry has been producing a large amount waste, untreated waste usually disposed to nearest river. It not only leads environmental problem, but it illegal under Environmental Quality Act 1974. Since still high content, which 58%, can be converted value-added products such as poul...

Fluidized beds have been widely used in power generation and in the chemical, biochemical, and petroleum industries. The 3D simulation of commercial scale fluidized beds has been computationally impractical due to the required memory and processor speeds. However, in this study, 3D Computational Fluid Dynamics simulation of a gas-solid bubbling fluidized bed is performed to investigate the effe...

The hydrodynamics in a 152 mm ID bubbling fluidized bed filled with 500-600 μm glass beads have been simulated using the computational fluid dynamics (CFD) code Fluent 6.3, and the results are compared to experimental data obtained using pressure measurements and 3D X-ray computed tomography. The grids in a Cartesian coordinate system used in simulations are made by 2D (8×8 mm, 4×4 mm, 2×2 mm, ...

the present research surveyed the effect of five factors including: microwaves power, air temperatures and its flow rates, microwaving time onset and amount of substances on the requested time and energy for combined fluidized bed- microwaves drying of black raspberry into 50% dry base wet content. response surface methodology and central composite was used as experimental design. multiple line...

In this study, a two-fluid nozzle, as, e.g., used in fluidized-bed or spray drying applications, is comprehensively characterized regarding the pattern and droplet size. To analyze cone, cone angle radial mass distribution of nozzle were measured at varied liquid flow rate, air pressure, insert bore diameter, cap position. Additionally, size distributions recorded different settings. general, o...
