“…Such liquid bridges have been reported in spray‐dried SMP and WMP (Palzer & Sommer, 2011). The moisture on particulate surfaces interacts with solids in powder leading to interparticle forces and formation of liquid bridges (Salehi et al, 2021). The liquid bridges between adjacent particles were reported to occur at A w above 0.85, causing stickiness and caking (Pushpadass et al, 2021).…”

The physical and flow properties of milk blended barnyard and foxtail millet powders were evaluated at different moisture contents. Particle‐size distribution and span decreased considerably as moisture increased. The d0.5 increased from 24.769 to 38.642 μm in milk‐barnyard millet powder and from 27.942 to 41.063 μm in milk‐foxtail millet powder as moisture increased from 3 to 9%. The dynamic flow and shear tests revealed the hygroscopic nature of both millet powders, wherein moisture and particle size were found to influence flowability. The basic flow energy and shear tests proved that both millet powders would flow easily at 9% moisture content than at 3% due to agglomeration and reduction in contact surface area of the particles and the magnitude of their interactions. Compressibility and wall friction tests also corroborated the fact that milk‐millet powders were relatively more cohesive at 3% moisture, manifesting difficulties in flow. Between milk‐foxtail millet and milk‐barnyard millet powders, the former had better flowability due to its larger particle size and narrower span than the latter.Practical ApplicationsPowders are dynamic systems whose behavior changes drastically with minor changes in the environment or moisture. In this study, the influence of moisture on physical and flow properties of milk‐millet powders were evaluated. The physical and flow properties of milk blended barnyard and foxtail millet powders were influenced by particle size and moisture content. The flow properties could be useful in understanding their behavior during handling, processing, and storage, and thus help in the design and optimization of processing and storage operations.

“…Experiments performed at the bulk level confirmed the conclusions of force analysis at the particle level. In fact, powder cohesion varied only for air humidity values higher than a critical value by analysing the results of shear tests (Elbirli et al, 1982;Karde and Ghoroi, 2015;Landi et al, 2011;Salehi et al, 2021;Stevens et al, 2009;Teunou and Fitzpatrick, 1999), torque and energy measurements in rheometers (Groen et al, 2020;Landi et al, 2012;Lu et al, 2017;Marchetti et al, 2022), and flowability indices in rotating drums (Lumay et al, 2016).…”

In several industrial units and applications, particulate solids are exposed to peculiar process conditions that significantly affect their flowability. Accurate characterisation and prediction of these effects are crucial for proper design and operation control of the processes. Liquid content, environmental humidity, and temperature can directly modify the type and magnitude of the interparticle forces and, thus, the cohesive behaviour at the bulk scale. This paper reports a critical review of experimental and modelling studies regarding the quantitative assessment of the effect of powder liquid content, environmental gas humidity and temperature on the mechanics of dense particle assemblies. Particular attention is paid to novel setups and experimental protocols that aim to go beyond the limits of standard and commercial instruments. A multiscale approach is followed from the particle level to the bulk level.

“…The effect of moisture content on powder flow properties has been extensively studied [22,23]. We conducted sensitivity flow function experiments for Aspen 10 and 12 (dry matter of 52% ± 1 and 49% ± 1) as well as Pine 10 and 12 (dry matter of 44% ± 1 and 48 ± 1%) to investigate the effect of the added moisture content on the flow properties of the tested biomass.…”
