- this global rate shows how long it takes to reach a target which relates to how much is left in the ingredients, which can be useful information in the case of multiple and successive brewings using the same initial ingredients.
- system according to the invention further comprises a system connected to said second unit for separating, upon the generation of said signal, the ingredients from the solvent.
- the first unit is further adapted to measure a subsequent change of the electro-conductivity of the solvent, said subsequent change of the electro-conductivity being defined as the difference between the electro-conductivity of the solvent at the time of separating the ingredients from the solvent, and the electro-conductivity of the solvent at a subsequent time; and wherein said second unit is further adapted to compare said subsequent change of the electro-conductivity with an additional predetermined threshold, to generate a signal indicating that a property of the solvent reflecting the solvent quality has changed.

- Fig.16 depicts a method according of the invention of preparing a beverage by brewing ingredients in a solvent.
- Fig. l depicts a system 1 for brewing ingredients 2 in a solvent 3.
- ingredients 2 in a solvent 3 are placed in a container 4.
- ingredients may correspond to tea leaves, coffee, herbs, roots, fruits, or a mix of those ingredients...
- the solvent may correspond to water, mineral water, tap water, salted water, alcohol, or a mix of those solvents.
- the system comprises: - a first unit 5 for measuring a change of the electro-conductivity AEC of said solvent,
- a second unit 6 for comparing said change of the electro-conductivity AEC with a predetermined threshold TH, to generate a signal S indicating that the ingredients should be separated from the solvent.
- the present invention is based on the fact that during the brewing of ingredients in the solvent, the electro-conductivity (EC) of the solvent varies linearly with the so-called degree Brix of the solvent.
- the degree Brix represents the amount of dissolved solids/compounds in the solvent, so that in the present case it can be used to quantify the amount of dissolved solids/compounds extracted from the ingredients during the brewing operation.
- the degree Brix reflects the concentration level of the solvent, i.e. the strength of the solvent in terms of taste if the solvent is intended to be drunk by a user.
- the amount of dissolved solids/compounds in the solvent is indirectly measured via measuring the EC of the solvent, by exploiting the linearity of variation between EC and degree Brix.
- Fig.2 illustrates an example of the EC variation of a solvent, according to different degree Brix values of the solvent.
- leaves of green tea are used as ingredients in water used as the solvent, with a concentration of leaves of 20 grams per litre.
- This variation shows the linearity between EC and degree Brix.
- the unit of EC is micro -Siemens/cm ( ⁇ / cm), and the unit of degree Brix is a percentage by mass of the solvent (% / weight).
- the first unit 5 for measuring a change of the electro- conductivity AEC is connected to an EC sensor 7.
- the EC sensor 7 is intended to generate the
- the first unit 5 is adapted to measure a change of the EC of solvent 3.
- the first unit 5 is adapted to make a relative measurement, not an absolute measurement.
- a relative measurement is preferred, so that solids/compounds that could already be present in the solvent at the start of the brewing operation are not taken into account in the measurement.
- this solvent may initially contain some minerals or different dissolved solids/compounds that should not be taken into account for determining the real contribution of dissolved solids/compounds extracted from the ingredients during brewing.
- the first unit 5 is adapted to measure the change of EC of solvent 3 according to different modes that may be used for different purposes.
- the first unit 5 is adapted to measure a change of the electro- conductivity AEC, defined as the difference between the electro-conductivity EC tl of the solvent at the time tl of measurement by the first unit, and the electro-conductivity EC tO of the solvent at the starting time tO of the brewing operation.
- the first unit 5 comprises a memory (not shown) to store EC tO.
- Fig.3 illustrates an example of a variation of ECl over time.
- AEC is expressed as:
- AEC (EC tl - EC tO)
- the second unit 6 makes a comparison between the measured AEC and a predetermined threshold TH.
- AEC reflects the amount of solids/compounds of the ingredients dissolved in the solvent so far
- the threshold TH corresponds to a given change of the EC value at which the brewing is considered optimal in terms of amount of solids/compounds of the ingredients dissolved in the solvent, resulting in an optimal taste of the solvent.
- the measured AEC reaches the threshold TH, it means that the materials have dissolved sufficient solids/compounds in the solvent, and that this solvent now has optimal taste/flavour.
- the second unit 6 generates signal S indicating that ingredients and solvent have to be separated, to avoid that the solids/compounds of the ingredients continue to dissolve in the solvent, which could badly affect the taste of the solvent.
- signal S may change from a low level "0" to a high level "1" to indicate that ingredients and solvent have to be separated.
- the threshold TH may be previously determined experimentally as follows. For example, during brewing, the change of AEC is regularly measured, and for each measurement of AEC, a user
- the threshold TH is thus stored in a memory (not shown) with a view to being used by the second unit 6 for a similar brewing operation.
- the first unit 5 is adapted to measure a change of the electro- conductivity AEC, defined as the ratio of:
- the first unit 5 comprises a clock (not shown) to measure the elapsed time of the brewing operation, and a memory (not shown) to store EC_t2 and time t2.
- Fig.4 illustrates an example of a variation of ECl over time.
- AEC is expressed as:
- AEC (EC_t3 - EC_t2) / (t3-t2)
- the second unit 6 makes a comparison between the measured AEC and a predetermined threshold TH.
- AEC reflects the speed of dissolution of solids/compounds of the ingredients in the solvent during a given time interval
- the threshold TH corresponds to a reference rate of the variation of EC during the same time interval.
- t3 and t2 may be such that the time difference (t3-t2) defining said time interval is in the order of minutes, for example from 1 to 10 minutes.
- the second unit 6 generates signal S indicating that ingredients and solvent have to be separated.
- signal S may change from a low level "0" to a high level "1" to indicate that ingredients and solvent have to be separated.
- the threshold TH may be previously determined experimentally as follows.
- the change of AEC is regularly measured, and for each measurement of AEC, a user (or a group of users) tastes the flavour of the solvent.
- the flavour of the solvent is considered optimal, for example in view of various criteria such as strength, bitterness, sweetness...
- the corresponding AEC is chosen as threshold TH.
- the threshold TH is thus stored in a memory (not shown) with a view to being used by the second unit 6 for a similar brewing operation.
- the first unit 5 is adapted to measure a change of the electro- conductivity AEC, defined as the ratio of:
- the first unit 5 comprises a clock (not shown) to measure the elapsed brewing time, and a memory (not shown) to store EC tO (and optionally to store time tO).
- FIG.5 illustrates an example of a variation of ECl over time.
- AEC is expressed as:
- AEC (EC_t4 - ECJO) / (t4 - tO)
- the second unit 6 makes a comparison between the measured AEC and a predetermined threshold TH. This is similar to mode 2, the difference being that the time interval is defined from the start time of the brewing operation.
- This mode can preferably be used in the case that ingredients require multiple successive brewings: the time it takes to reach the threshold TH indicates how much of the solids/compounds is left in the ingredients. If it takes too long to reach this threshold, it indicates that the raw ingredients have already dissolved most of their solids/compounds in the solvent, and that it is not relevant to perform another brewing with those ingredients.
- the system according to the invention advantageously comprises a system connected to said second unit 6 for separating, upon generation of said signal S, the ingredients from the solvent.
- This system is described in the following.
- said first unit 5 is further adapted to measure a subsequent change of the electro-conductivity AEC of the solvent.
- the subsequent change of the electro-conductivity AEC is defined as the difference between the electro-conductivity EC_t5 of the solvent at the time t5 of separating the ingredients from the solvent, and the electro-conductivity EC_t6 of the solvent at a subsequent time t6.
- the second unit 6 is further adapted to compare said subsequent change of the electro-conductivity AEC with an additional predetermined threshold TH7, to generate a signal SI indicating that a property of the solvent reflecting the solvent quality, has changed.
- the time t6 can advantageously be set periodically, for example every minute, to so that the subsequent change of the electro-conductivity AEC is measure at different successive instants over the time.
- ingredients used for brewing for example tea
- catechins can oxidize and induce deteriorate in taste and color of the solvent.
- Ascorbic acid oxidizes and subsequently reacts with amino acids to form brown colored compounds.
- Some flavour related unsaturated fatty acids oxidize and form volatile aldehydes and alcohols with the formation of aged and rancid taste. It is thus advantageous to know the change of solvent quality and warn consumers for any quality degradation of the solvent.
- the signal SI can be displayed on a user interface.
- Fig.6 depicts a first embodiment of a system for separating the ingredients from the solvent. It comprises a pipe 8 which is connected to the bottom part of container 4, and which communicates with a second container 9 via a valve 10.
- the valve 10 which may correspond to an electro valve, is controlled by signal S generated by the second unit 6.
- signal S indicates that the ingredients have to be separated from the solvent
- the valve 10 opens, so that the solvent 3 leaves container 4 via pipe 8 and fills container 9. The ingredients thus remain in the container 4, as illustrated in Fig.7.
- Fig.8 depicts a second embodiment of a system for separating the ingredients from the solvent.
- an infuser 8 is placed in the container 4, and the infuser is intended to contain the ingredients 2.
- a pump 9 is placed, and the exit of the pump is connected to a pipe 10 reaching an upper part of infuser 8.
- the pump for example an electrical pump, is intended to pump the solvent 3 from the lower part of container 4 to the upper part of infuser 8, and is controlled by signal S generated by the second unit 6.
- the solvent in infuser 8 then drops back into container 4, which is illustrated by arrows A2.
- Pumping the solvent from the container 4 into the tube 10, infusing the ingredients in the infuser 8 with solvent contained in the infuser, and subsequently the solvent from the infuser dropping back into the container, constitutes a closed brewing cycle that is continued until the second unit 6 generates signal S indicating that the ingredients have to be separated from the solvent.
- Generation of signal S is thus used to stop the pump 9, resulting in the situation that the ingredients are separated from the solvent by stopping the brewing cycle.
- Another approach could also be used to separate ingredients from the solvent. For example, in a system as described in Fig.l, when the second unit 6 generates signal S indicating that the ingredients have to be separated from the solvent, this signal could trigger a visual indication
- Fig.12 depicts a system 1 according to the invention, further comprising a third unit 1 1 adapted to generate a signal SS reflecting the progress of the brewing, based on a ratio between said change of the electro-conductivity AEC and said predetermined threshold TH.
- This signal may advantageously be used to control a set of visual indicators placed on a user interface 12.
- visual indicators L1-L2-L3-L4 for example light emitting diodes (LED)
- the visual indicators can be controlled by the third unit 1 1 as follows:

- - means SEL1 for selecting a type of ingredients to be brewed
- - means SET1 for setting the predetermined threshold TH to the value of the threshold associated with the selected type of ingredients.
- the plurality of thresholds may correspond to thresholds according to mode 1, mode 2 and/or mode 3. It is noted that only three thresholds are used in this description, but the number of thresholds could be different without departing from the scope of the invention. Thresholds are experimentally defined as previously described. For example: - TH1 is associated with the brewing of green tea as the ingredient, in water as the solvent,
- - TH2 is associated with the brewing of black tea as the ingredient, in water as the solvent,
- the means SEL1 for selecting a type of ingredients may correspond to a mechanical switch or a digital switch placed on the body (not shown) of the apparatus.
- the user can select the ingredients to be brewed, either by rotating a mechanical switch until the switch faces the desired ingredients illustrated as a pictogram or text on the apparatus body, or by scrolling in a menu displayed on an LCD display (not shown) until the desired ingredients illustrated as a pictogram or text are displayed on the display.
- the means SET1 for setting the predetermined threshold TH may correspond to a mechanical switch following the movement of the mechanical switch SEL1 (which is illustrated by dotted lines joining the means SEL1 and the means SET1). Alternatively, this can be performed digitally by converting the selection made by the user on the LCD display into an address sent directly to the memory MEM1.
