Flow Properties of Spices Measured with Powder Flow Tester and Ring Shear Tester-XS

A Numerical Method for the Calculation of the Powder Flow Properties Obtained with the Jenike Flow Factor Tester

In this equation (T and 7 are the normal and shear stresses respectively, C and T the cohesion and tension, and N a curvature parameter constant for one material. Based on this equation and assuming a constant ratio K = C/T, several partly graphical, partly numerical solution methods are known. The pure numerical method described in this article has several advantages over the graphical methods...

Data flow within an open architecture tester

An open architecture tester allows a third party to develop its own instrument. Such a tester must be open in the sense that it needs to be able to integrate this instrument with minimal or no impact on the overall performance and cost. It is therefore fundamental that the data flow and synchronization among all the instruments in an open architecture tester be efficient. One of these two key t...
