Definitions
- the present invention relates to a method for operating a coffee machine for preparing a coffee drink.
- the invention also relates to a coffee machine with a device for carrying out such a method and a corresponding computer program product.
- a method for the user-controlled production of a particularly liquid food product in which gustatory, olfactory and/or haptically perceptible pleasure substances are extracted from a precursor product by an automatic machine and transferred into the food product.
- the extraction of the pleasure substances is influenced by a user-controlled setting of at least two technical parameters of the machine in order to be able to produce the desired quality of the food product.
- the technical parameters required for this are set by a user-controlled electronic translation circuit, which controls the technical parameters during production based on user-selected values of the human sensory attributes and on the basis of a previously determined sensory profile of the preliminary product. This should make it possible to set a desired taste, smell or texture of the food product more precisely.
- an automatic coffee machine for preparing coffee drinks by pouring coffee powder which has a control and monitoring device which is configured in such a way that it adapts at least one operating parameter of a pre-infusion step and selects it from: A throughput of the Pre-infusion water, a quantity of the pre-infusion water and a duration of the pause at the end of the pre-infusion step and this depending on a granulometry of the coffee powder.
- some coffee machines have a corresponding device through which the grinding degree can be adjusted manually by a user.
- a device for adjusting the grinding degree of the coffee powder is of no use to him or even leads to the wrong grinding degree being selected for the desired coffee drink, in some cases a coarse grinding degree setting for an espresso.
- the present invention therefore deals with the problem of specifying a method by means of which, in particular, comfortable coffee preparation can be significantly increased, even for users with little or no coffee preparation knowledge.
- the present invention is based on the general idea of automatically selecting a grinding level of coffee powder for producing a coffee drink and thereby making it easy for users with little or no knowledge of coffee to prepare tasty coffee drinks.
- a desired coffee drink is selected by a user during the automated setting of the grinding degree, whereupon a device determines a grinding degree associated with the selected coffee beverage and transmits it to a grinder, which then produces the coffee with the transmitted grinding degree , that is, grinds with a predefined fineness.
- the he- The method according to the invention can be provided to the user, for example, by means of a so-called aroma boost function, which, when activated by the user, automatically selects the grinding degree corresponding to the method according to the invention and thus optimally adapted to the desired coffee drink.
- a so-called aroma boost function which, when activated by the user, automatically selects the grinding degree corresponding to the method according to the invention and thus optimally adapted to the desired coffee drink.
- This not only makes it possible to use a coffee machine extremely conveniently, but also allows for a better coffee taste and thus higher customer satisfaction.
- a particular advantage is that a user can obtain the optimal grinding level for their desired coffee drink even without detailed coffee knowledge.
- a coffee machine carrying out this method according to the invention can only offer the aroma boost function as an option, so that the user can also or alternatively set the grinding level manually, in order to enable, in particular, experienced users with at least little barista knowledge to individually prepare their coffee drinks make possible.
- the device takes the grinding degree associated with the selected coffee drink from a stored characteristic map.
- a stored characteristic map for example, each coffee drink that can be prepared by a coffee machine, for example an espresso or a cafe crema, can be assigned a specific grinding degree, so that by selecting the desired coffee beverage and activating the method according to the invention, the desired coffee drink is produced with the optimal grinding degree for it becomes.
- other parameters for the desired coffee drink can also be stored in this map, such as the amount of coffee, amount of water, brewing time, etc.
- the grinding level associated with the respective selected coffee drink can be determined, for example, using appropriate evaluations and stored in the map.
- the device determines the degree of grinding associated with the selected coffee drink based on the amount of drink to be dispensed. This is done against the background that, for example, for large-volume coffee drinks, such as a cafe crema, in which there is a longer contact time between a brewing water and the ground coffee powder, a coarser grind is selected in order to avoid undesirable loosening Avoid bitter substances from the ground coffee powder.
- a coarser grind is selected in order to avoid undesirable loosening Avoid bitter substances from the ground coffee powder.
- the grinding level can be set correspondingly finer, i.e. the coffee powder is ground correspondingly finer, since the contact time between the brewing water and the coffee powder is shorter and therefore the surface area of the ground coffee powder should be larger if possible, so that the espresso can absorb as many aromas as possible.
- the device determines the degree of grinding associated with the selected coffee beverage based on a brewing temperature associated with the selected coffee beverage.
- a brewing temperature associated with the selected coffee beverage.
- an espresso usually requires a brewing temperature between 92 and 96 °C, while other types of coffee drinks, such as a cafe crema, require a lower brewing temperature. If the brewing water is very hot, the coffee made from it often tastes bitter because the higher brewing temperature releases many bitter substances from the ground coffee. If the brewing temperature is too low, the coffee drink produced tastes slightly sour or watered down, since in this case not enough aromatic substances are released from the ground coffee powder, but rather acids, which are the first to be extracted from the ground coffee powder during the extraction process.
- the brewing temperature usually also correlates with the selected coffee drink or the associated amount of drink.
- the device determines the degree of grinding associated with the selected coffee beverage based on a brewing time associated with the selected coffee beverage.
- a long brewing time requires a coarser grind, otherwise too many bitter substances are released from the ground coffee powder and can give the coffee drink a bitter taste.
- the brewing time is significantly shorter, such as for an espresso, the method according to the invention selects a finer grind and thus a higher grinding fineness of the coffee powder to be ground in order to provide the brewing water with a sufficiently large surface area for extracting the aromatics required for an optimal coffee taste .
- the device determines the degree of grinding associated with the selected coffee drink based on an amount of powder associated with the selected coffee drink.
- the grinding level can also be adjusted depending on the amount of powder. Specifically, this means that a higher grinding fineness is selected with a smaller amount of powder than with a larger amount of powder.
- the device determines the degree of grinding of the coffee powder associated with the selected coffee drink based on a brewing pause associated with the selected coffee drink.
- a brewing pause takes place between a pre-brewing phase and a main brewing phase, with such a brewing pause meaning an extension of the contact time of the brewing water in contact with the ground coffee powder.
- the brewing pause can depend on the coffee drink you want.
- the grinding degree is manually adjusted by the user in a comfort mode, in particular fine, medium or coarse. If the user then activates the aroma boost function, the device increases the grinding level, for example for all coffee drinks containing espresso, compared to the manually set grinding level. This gives the user the opportunity to adjust the grinding level themselves in comfort mode and supports them with the aroma boost function.
- the present invention is further based on the general idea of specifying a coffee machine for preparing a coffee drink, with an input device, a grinder and a device designed to carry out the method according to the previous paragraphs.
- a coffee machine for preparing a coffee drink, with an input device, a grinder and a device designed to carry out the method according to the previous paragraphs.
- a coffee machine even inexperienced users can produce a wide variety of tasty coffee drinks, such as espressos or cafe crema, relatively easily, since the optimal grinding level associated with the respective coffee drink is automatically preset by operating the device or the aroma boost function.
- a corresponding input device for example a Display
- a grinding level can be selected automatically, for example fine, medium or coarse, especially if the respective user is familiar with the preparation of coffee drinks and therefore has a certain knowledge of coffee.
- the coffee machine according to the invention it is therefore possible for all users, regardless of whether they have special coffee knowledge or not, to produce coffee drinks with optimal taste.
- Fig. 1 shows a coffee machine according to the invention.
- a coffee machine 1 has an input device 2, via which a user can select individual coffee drinks. These are then produced within the coffee machine 1 and dispensed via a drinks outlet 3. Arranged within the coffee machine 1 are also a grinder 4 and a device 5 with which a grinding degree of the grinder 4 can be adjusted.
- the coffee machine 1 according to the invention is designed to carry out a method according to the invention, in which a grinding degree of coffee beans can be adjusted automatically.
- the user first selects a desired coffee drink, for example an espresso or a cafe crema, via the input device 2.
- different touch panels 6 can be provided on the input device 2, for example, whereby the input device 2 can generally be designed as a touchscreen.
- push buttons are of course also conceivable.
- the user has selected the desired coffee drink using one of the touch panels 6, he can then decide whether he wants to select a grinding level himself using a comfort button 7 or whether he wants to leave the setting of the grinding level to the device 5 using an aroma boost button 8. If the user presses the aroma boost button 8 after selecting the desired coffee drink via the respective keypad 6, the grinding level is automatically adjusted using the device 5 depending on the selected coffee drink.
- the selection of the aroma boost function can also be generally available in the settings menu for all drinks. It is possible that the function can only be activated for espresso drinks and/or for larger coffee drinks.
- the user can first set the grinding level themselves, in particular fine, medium or coarse, by pressing the comfort button 7. If the user then presses the aroma boost button 8, the device 5 can increase the grinding level, for example for all coffee drinks containing espresso, compared to the manually set grinding level. This can support the user.
- the aroma boost button 8 automatically determines the fineness of the grind, ie the degree of grinding, of the cafe used to produce the desired coffee drink. This can result in a grind that is too fine, for example with a cafe crema or a grind that is too coarse, for example with an espresso, can be reliably avoided.
- the device 5 can take the degree of grinding associated with the selected coffee drink from a stored map, it being additionally or alternatively also conceivable that the device 5 determines the degree of grinding associated with the selected coffee beverage based on a quantity of beverage to be dispensed. For example, if the amount of drink to be dispensed is less than 100 ml, the device 5 assumes that it is, for example, an espresso, in which the grinding level must be set much finer than with a larger-volume coffee drink, such as a cafe crema.
- the device 5 can also determine the degree of grinding associated with the selected coffee drink based on a brewing temperature associated with the selected coffee drink, since such a brewing temperature is usually also dependent on the selected coffee drink.
- the device 5 can determine the degree of grinding associated with the selected coffee beverage based on a brewing pause, brewing time and/or amount of powder associated with the selected coffee beverage. These parameters also determine the taste of the coffee drink to be produced, since, for example, an espresso has a significantly shorter brewing time than a cafe crema and therefore requires an increased degree of grinding in order to provide the larger surface area required for the short brewing time in order to release a sufficient amount of aromatic substances from the coffee This allows us to produce a tasty coffee drink.
- the coffee machine 1 according to the invention it is of course also possible by pressing the comfort button 7 for the respective user to set the grinding level themselves, so that the coffee machine 1 according to the invention is available to all users, ie both those with little or no knowledge of coffee, as well as those users offers a significant increase in comfort with coffee knowledge.
- the method according to the invention can particularly benefit users with little or no knowledge of coffee, since they can achieve an optimal grinding level for the desired coffee drink using the aroma boost button 8 according to the invention.
