Device, for dosing powdered coffee for automatic coffee machine, measures current pressings height during percolation, derives correction factor for last milling process duration for use in next process

摘要

The device has a coffee mill and a control unit connected to a memory and an arrangement for determining the height of the pressed milled coffee in the boiling chamber. The memory provides a milling duration and pressing reference height reference parameter pairs. The control unit measures the current pressings height during percolation and derives a correction factor for the actual duration of the last milling process for use in the next process.
