  • Effects of insect-infested kernels on bulk flow properties of wheat

    Bian, Qi   Ambrose, R.P. Kingsly   Subramanyam, Bhadriraju  

    Highlights • Moisture content had significant effect on bulk physical properties of wheat. • Presence of insect infested kernels affects the physical and flow properties of bulk wheat. • Insect infested kernels increase the angle of repose of bulk wheat. • Dust produced from insect activity increases the chances of localized compaction of wheat in grain bins. Abstract Insect damage to kernels during storage affects the processing quality of wheat and as well as bulk wheat properties, which in turn causes hopper flow problems such as funnel flow, ratholing, arching, or flushing. This study focused on kernel damage by Rhyzopertha Dominica F. (lesser grain borer), one of the most commonly found insects in wheat, and resulting changes in physical properties, such as bulk density, tapped density, true density, and angle of repose, and in flow properties, such as basic flowability energy, stability, aeration, compressibility, and permeability. Bulk and tapped densities of sound hard red winter wheat kernels and infested wheat kernels were about 720 kg/m3 and 775 kg/m3, respectively. Compressibility index (CI), Hausner ratio (HR), and angle of repose of infested wheat kernels were higher than for sound hard red winter wheat kernels, indicating decreased flowability. Grain dust and insect-infested kernels could form localized compacted areas within the grain bins, resulting in uneven flow during discharge. Results from this study indicate that the presence of insect-infested kernels could lead to arching and bridge formation in grain bins, thus affecting the flow characteristics of bulk wheat.

  • Bulk flow properties of hard and soft wheat flours

    Bian, Qi   Sittipod, Sichaya   Garg, Anubha   Ambrose, R.P. Kingsly  

    Highlights • Flour from soft wheat was cohesive than hard wheat flour. • Wheat flour do not agglomerate during handling. • Hard wheat flour has higher air permeability compared to soft wheat flour. • The tests indicated soft winter wheat flour flowability is lesser than hard red winter wheat flour. Abstract Hard red winter (HRW) and soft white winter (SWW) wheat flours are commonly used in bakeries, preparation of snacks, cereals, and ready-to-eat food. The quality of the end product depends on the wheat and flour processing conditions which, in turn, depend significantly on the flow properties of the ingredients. This study describes a comparative evaluation of the flow properties of a HRW and a SWW flour. The average particle size of HRW and SWW wheat flours was 48.77 and 48.20 μm, respectively. The bulk and tapped density of HRW flour was significantly higher than SWW flour. The aeration ratios for HRW and SWW were found to be 16.69 and 12.67, respectively. The wall friction angle for SWW flour was higher than that of HRW flour. HRW and SWW flour had distinctly different flow properties due to their difference in intrinsic physical and chemical composition. The results indicate that SWW flour had higher cohesiveness than HRW flour and has lesser flowability than HRW flour.

  • Effect of chaff on bulk flow properties of wheat

    Bian, Qi   Ambrose, R.P. Kingsly   Subramanyam, Bhadriraju  

    Highlights • Flowability of bulk wheat reduces with increase in moisture content and percent chaff. • Energy required to initiate flow of wheat with chaff is higher than for clean wheat. • Compressibility of wheat increases with chaff percentage. • During handling, there exists minimum segregation potential of chaff from clean wheat. Abstract Consistent and reliable flow of bulk wheat from hoppers and silos is vital in handling, processing, and storing wheat. The presence of impurities in bulk wheat might influence the discharge of wheat from hoppers and storage vessels. Chaff is one common impurity, amounting to about 2–7% (weight basis) in bulk wheat. This study focused on measuring the bulk and flow properties of bulk wheat in the presence of chaff at different moisture content levels. Bulk density, tapped density, and true density varied from 805.50 to 718.36 kg/m3, 831.52 to 746.31 kg/m3, and 1404.63 to 1367.13 kg/m3, respectively, with varying chaff proportions and moisture contents. The stability of bulk wheat samples remained the same, indicating that sample properties did not change during repeated handling. Compressibility ranged from 4.84 to 7.99%. The unconfined yield strength (UYS) of chaff was approximately 3 times higher than clean wheat samples. High UYS values indicate that arching could occur during bin discharge of bulk wheat containing impurities.

  • Preparation of poly{styene-co-4-(4-vinylphenoxy) phthalonitrile} nicrospheres by a new approach of “co-dissolution” and its function development

    Bian, Qi   Qiu, Kai   Liu, Jiaojian   Niu, Yancun   Liu, Yancui   Hu, Jianghuai   Zeng, Ke   Yang, Gang  

    Solid vinyl monomer with functional group “phthalonitrile” was successfully introduced into microspheres to make poly{styene-co-4-(4-vinylphenoxy) phthalonitrile} microspheres (PSPMs) with uniform (UPSPMs) and core-shell (core-shell PSPMs) structure using soap-free emulsion polymerization by the new approach of “codissolution”. The core-shell PSPMs then were used as the design platform to make metallophthalocyanine-containing microspheres. EA, FTIR, SEM, TEM, UV-vis, TGA, XPS, solid 1H NMR and XRD techniques were employed to analyze the formation and morphology of PSPMs and metallophthalocyanine-containing microspheres. The results showed that UPSPMs and core-shell PSPMs were both realized and they were regular sphericities with diameters of around 370 nm. The percentages of reacting weight of 4-(4-vinylphenoxy) phthalonitrile were close to 50%. Based on the design platform of core-shell PSPMs, metallophthalocyanine-containing microspheres could be obtained and the content of metallophthalocyanine was close to 19%.
