Influence of water activity on the compressibility and mechanical properties of cocoa products
TL;DR: In this paper, the influence of content (cocoa, crystal and sugar powders, milk powder and maltodextrin) and water activity (at three levels of 0, 0.34 and 0.65) on compressibility and mechanical properties of cocoa products were determined according to the Jenike test.

TL;DR: Investigation of the compaction properties of both wet and jet milled powder blends revealed that both jet and wet milled material produced robust tablets at the drug loadings used, and showed clear trends in flow functions based on API particle size.

Effect of Passive Inserts on the Granular Flow from Silos Using Numerical Solutions
Abstract: Experimental investigations indicate that placing a passive insert in a silo is a method for influencing the discharging flow pattern. These inserts have consisted of an inverted cone, a cone-in-cone, and a double cone. However, providing unequivocal guidelines on where those inserts should be placed for an optimum effect has not been possible experimentally. A numerical approach was therefore developed to predict material flow in the presence of such inserts in silos. Simulation results showed that all these inserts could make a funnel-flow silo perform in mass flow under certain circumstances if positioned correctly. The inserts should be installed at higher levels close to the transition rather than at lower positions close to the outlet, especially with the cone-in-cone insert and the inverted inserts; the maximum diameter of the inverted cone and the double cone should, however, be below the transition of the silo. Among the three inserts investigated, the double cone appeared to be the best, althoug...

Model tests of silo discharge in a geotechnical centrifuge
J.C. Mathews,Wei Wu +1 more
TL;DR: In this paper, the effects of gravity on silo discharge and internal flow patterns are investigated with reference to the widely used Beverloo correlation, and it is shown that the width of the flow channel at any given height above the outlet is independent of gravity and the local velocity of discharging material is proportional to the square root of gravitational acceleration.
