Abstract

A compacting auger for ground coffee has an automatic cut off that responds to either timing signals or to the torque resistance to the augur offered by the coffee that has been compacted. The automation of the cut off increases the consistency of compaction and reduces the amount of skill required to compact ground coffee for making espresso.
