Abstract
A method and device for producing a beverage from a capsule containing at least one beverage ingredient are disclosed. The device is configured to carry out the method by feeding a first volume of water into the capsule for prewetting the at least one beverage ingredient, interrupting the flow of water into the capsule for a predetermined waiting time, feeding a second volume of water into the capsule for extracting the at least one beverage ingredient, and dispensing the produced beverage.
Claims16
A method for producing a beverage from a capsule containing at least one beverage ingredient, the method comprising:
- feeding a first volume of water into the capsule for prewetting the at least one beverage ingredient;
- interrupting the flow of water into the capsule for a predetermined waiting time;
- feeding a second volume of water into the capsule for extracting the at least one beverage ingredient;
- and
- dispensing the produced beverage;
- and
- wherein a time point of interrupting the flow of water into the capsule is determined by evaluating a measurement signal output by a flow meter that measures the flow of water into the capsule, and wherein the time point is determined at least based on a gradient of a flow rate gradient evaluated from the measurement signal of the flow meter.
A device for producing a beverage from a capsule containing at least one beverage ingredient, the device comprising:
- a pump for feeding water from a water reservoir into the capsule;
- a flow meter for measuring the flow of water into the capsule and for outputting a measurement signal to a control unit, wherein the measurement signal is evaluated by a moving window averaging method calculated on a predetermined number of samples and with a predetermined filter time, the control unit being configured to:
- control the pump to feed a first volume of water into the capsule for prewetting the at least one beverage ingredient,
- interrupt the flow of water into the capsule for a predetermined waiting time, and
- control the pump to feed a second volume of water into the capsule for extracting the at least one beverage ingredient,
- dispensing means for dispensing the produced beverage from the capsule, and
- wherein the control unit is configured to determine the time point of interrupting the flow of water into the capsule by evaluating a measurement signal of the flow meter.

- feeding a first volume of water into the capsule for prewetting the at least one beverage ingredient;
- interrupting the flow of water into the capsule for a predetermined waiting time;
- feeding a second volume of water into the capsule for extracting the at least one beverage ingredient;
- and
- dispensing the produced beverage;
- and
- wherein a time point of interrupting the flow of water into the capsule is determined by evaluating a measurement signal output by a flow meter that measures the flow of water into the capsule, and wherein the measurement signal of the flow meter is evaluated by a moving window averaging method calculated on a predetermined number of samples and with a predetermined filter time.
