Research about improving flowability of powder of Chinese
In this study, modification technology by surface coating was used to improve the flowability of powder of Chinese herbs extracts. Seven kinds of powder of Chinese herbs extracts were coated with 1% silica nanoparticles using an under-driven Comil.
[Improvement of Powder Flowability and Hygroscopicity
To study the improvement of powder flowability and hygroscopicity of traditional Chinese medicine extract by surface coating modification technology. The 1% hydrophobic silica nanoparticles were used as surface modifier, and andrographis extract powder was taken as a model drug.
Improving Powder Flow During Pharmaceutical Operations | Rx
Therefore, a more accurate definition of powder flowability is the ability of a powder to flow in a desired manner in a specific piece of equipment. The specific properties of a powder that affect its flow are known as flow properties. Examples of flow properties include bulk density, permeability, cohesive strength, and wall friction.
Dry Particle Coating for Improving the Flowability
The decrease in the flowability of the 2 h ball-milled powder compared to the Ti-6Al-4V powder was attributed to the mechanical interlocking and the entangling caused by the B4C particles fully
[Improvement of powder flowability and hygroscopicity
The percentage of Si element on the powder surface was measured by energy dispersive spectrometer. The hygroscopicity of powder was determined by Chinese pharmacopoeia method. All of the three techniques can improve the flowability of powder extract. In particular, hygroscopicity of extract powder can also be improved by dispersion and then
Experimental investigation on the flowability properties
The flowability properties of two carbonaceous powers (anthracite coal and petroleum coke), including angle of repose (AOR), Hausner ratio (HR) and powder compressibility (C), etc., were determined. The effects of particle size, external moisture content (MC) and power type on powder flowability properties were investigated.

Shelf life and storage stability of spray-dried bovine
The colour values of powder samples were measured as CIE parameters L, a, and b using a colour difference meter (Model WSC-S, Shanghai precision & scientific instrument co., Ltd, Shanghai, China). The L, a, and b values of the stored powder were measured and the net (total) colour difference ( E) was calculated using Eq.
