Abstract
In a coffee brewing apparatus, a milling assembly produces coffee powder which is filled into a brewing chamber. Then the brewing chamber is closed by a displaceable piston in order to exert a preselected pressure on the coffee powder in the brewing chamber, and hot water is forced through the compressed coffee powder. If it is recognized after several subsequent preparation cycles that too much or too less coffee powder has been filled into the brewing chamber, the operation period of the milling assembly is shortened or extended automatically under the influence of a programmed control unit. Simultaneously or additionally, a flow rate detector measures the amount of water flowing through the compressed coffee powder and the control unit measures the time required by the water to pass through the coffee powder in the brewing chamber. If a deviation of the measured time from a reference value is detected, the milling rate is adjusted to produce finer or coarser coffee powder in one of the subsequent preparation cycles. Minor deviations within normal tolerances are ignored.
