In order to compare and optimize powders regarding flowability and to design powder handling equipment like silos, feeders, and flow promoting devices, it is necessary to know the mechanical properties – the so-called flow properties. In the present paper it is outlined which physical parameters describe the flow properties of a powder or a bulk solid, and how these parameters are determined ex...

This work evaluates the physical properties affecting the flowability of the commercial rice flour. This flour/ powder were selected because of the flow issues encountered by the mills/ industries during bulk handling. A number of powder physical properties, including moisture content, particle size distribution, bulk density, compressibility index, angle of repose and co-efficient of friction ...

The intensive production of various biomedical composites made from different biomaterials showed a huge volume of information on properties of composite materials for appropriate research field. The matrix of composite materials is very important but the reinforcement materials known as fillers play an important role for the final properties of biomedical composites like mechanical properties ...

OBJECTIVES To use computational fluid dynamics (CFD) for evaluating and understanding the performance of the high-dose disposable Twincer™ dry powder inhaler, as well as to learn the effect of design modifications on dose entrainment, powder dispersion and retention behaviour. METHODS Comparison of predicted flow and particle behaviour from CFD computations with experimental data obtained wit...

In this research, an industrial spray dryer was used and the effects of atomizer speed on the physicochemical properties of milk powder, the textural and sensory characteristics of white cheese made from this milk powder were evaluated. For this purpose, whole milk was converted into powder by using three different speeds (10,000, 11,000, and 12,000 rpm). The results showed that by increasing a...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

Peripheral nerve injuries (PNI) can lead to lifetime loss of function and disfigurement. Different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. Designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. Utilization of absorbable and non-absorb...
