Notes:
The compaction behavior of two dehydrated potato granule materials has been studied in a cylindrical geometry. the effect of moisture content and the addition of dehydrated potato flake and potato starches has also been considered. the coefficient of friction and the stress anisotropy factor have been calculated from the pressure transmission measurements using a semi-particulate analysis previously used for polymer powders. the two granule types behaved more similarly under those conditions than their Brabender consistencies implied. the stress anisotropy factor tended to unity with increasing moisture content. the presence of other potato materials had a considerable effect on the compaction of the granules. These results indicate that the performance of processes that involve compaction of these materials, such as extrusion, will vary considerably with composition and moisture content.
