FIELD: machine building.SUBSTANCE: invention relates to a compaction auger for ground coffee. Auger has an automatic switch responding either to synchronisation signals or torque resistance, created by compacted coffee. Auger has a motor which drives a first shaft connected by means of coupling with a second shaft. Angular displacement between shafts provides activation of automatic switch.EFFECT: thus, automatic switch increases uniformity of compressing and reduces requirements for training compaction of ground coffee preparation, in particular, espresso.18 cl, 17 dwg |
