2. The method according to claim 1, characterized in that the data filed in the random-access memory is retrieved via an interface and is used for statistical surveys and/or for license-based, commercial billing.

3. The method according to claim 2, characterized in that the retrieved data is transferred into a central server via the Internet.

4. The method according to claim 1, characterized in that in supplying the package to the grinding mill, an automatic opening of the package is performed, such that the quantity of the grinding stock to be supplied per temporal unit is determined and the opening size is predefined by means of the first data.

5. The method according to claim 1, characterized in that the grinding mill control unit is in intercommunication with an input device for manually influencing the grinding process.

6. The method according to claim 1, characterized in that by means of a display, the first to third data is optionally visualizable, wherein the course and the respective state of the grinding process is represented via the display.

7. The method according to claim 6, characterized in that via the display, disturbances, service instructions and information regarding the third data are displayed to the user.

8. The method according to claim 1, characterized in that the grinding stock or the respective grinding stock mixture contains seeds, pulses, cereals, spices, nuts or the like.

9. A device for treating granular grinding stock or grinding stock mixtures by way of controlled mechanical size reduction by means of a grinding mill or a combination of several grinding mills, characterized in that the at least one grinding mill is located in a housing, wherein within or at the housing, a grinding stock feeding funnel and a grinding mill control unit are provided, the grinding mill control unit has a first interface for reading in data in a wireless manner from an external data memory, furthermore, a second interface is formed for an interconnection with a WLAN, a telecommunication network or the like for transmitting data to a server.

10. The device according to claim 9, characterized in that an operating and display unit is provided for manually inputting data as well as for displaying data and functions.

11. The device according to claim 9, characterized in that at or within the grinding stock funnel, a means for forming an opening in a targeted manner is formed for feeding the grinding stock per temporal unit.

12. The device according to claim 11, characterized in that the means for forming an opening comprises a cutting mill or similar means, which is capable of creating an opening in the supplied grinding stock package.

Description

[0026] The device according to the invention for the treatment of granular grinding stock or grinding stock mixtures by way of controlled mechanical size reduction by means of a grinding mill or a combination of grinding mills assumes that the at least one grinding mill is located in a housing, wherein within or at the housing, a grinding stock feeding container and a grinding mill control unit are provided. The grinding mill control unit has a first interface for reading in data in a wireless manner from an external data memory.

[0027] Furthermore, a second interface is formed for an interconnection with a WLAN, a telecommunication network or the like for transmitting data to an external server.

[0028] The device also has an operating and display unit for manually inputting data as well as for displaying data and/or functions.

[0029] Via the mentioned WLAN interface, but also the possibility of establishing a Bluetooth connection to a mobile telecommunication device, an individual evaluation of grinding processes, a collection of recipes, an assessment of the grinding stock or the like may be made via an application software that may be installed there.

[0030] In a preferred configuration of the invention, a means for forming an opening in a grinding stock package in a targeted manner is formed at or in the grinding stock feeding funnel. This opening may be a mechanical cutting unit defining the opening size while resorting to recipe-specific or grinding stock-specific data, so that only that quantity of grinding stock reaches the grinding mill from the package via the feeding funnel which can be processed per temporal unit at the desired quality.

[0031] In an alternative embodiment of the device, the corresponding package container including its content is completely supplied to the grinding stock feeding funnel. At the output side end of the relevant funnel, an adjustable, shutter-like opening is present in this embodiment so as to control the inflow of the grinding stock or the respective grinding stock mixture according to the grinding stock properties in this respect.

[0032] The device according to the invention results in conjunction with the presented method in a particularly user-friendly solution in crushing granular grinding stock, wherein the grinding success and thus the quality of the treated grinding stock is secured. Operating errors are likewise excluded according to the invention as is the processing of unsuitable materials or such materials the shelf life of which is exceeded.

[0033] In the case that the grinding mill/s is/are driven electromotively, there is the possibility according to the invention to log the grinding process via an acquisition of the respective effective power of the grinding mill motor/s.

[0034] If it is determined here that deviations from predefined set point data, i.e. abnormal power peaks have to be recorded, an abnormal grinding process may be concluded. Thus, for example, it is recognizable when the grinding stock includes third-party products or when there are disturbances in the grinding mill itself. If during the provision and packaging of grinding stock, for example, metallic foreign bodies get into the grinding stock, this can be recognized while observing the evaluation of effective power measurement data, and a further utilization, in particular a consumption of the crushed grinding stock can be prevented. The same applies in the event that in a grinding mill including a grinding stone, for example, fragments of it get into the crushed stock.
