ABSTRACT:
This invention relates to an on-line instrument that is able to sample the contents of a dense paste-like material, isolate the material, measure the material's rheological properties by extruding it under pressure and perform a self-cleaning operation. Such structures of this type, generally, provide precise measurements of the material's rheological properties (deformation and flow under pressure) such as yield stress, yield pressure, viscosity or Bingham number.
