Technical Field

The invention relates to a method and a device according to claims 1 and 9 for treating a granular grinding material or a grinding material mixture by means of controlled mechanical comminution by means of a grinding mill or a combination of grinding mills.

Background

An automatic dispensing unit for dispensing a granular product, for example coffee, into a collecting unit is previously known from US 7464888B 2, which dispensing unit has a milling device for milling the product and an identification device for identifying the size of the collecting unit.

In the method for brewing a beverage with an brewing device according to US 9591862B 2, the brewing formula is called up based on the selection of the brewing formula and the pumping length is calculated based on the target fluid volume given in the brewing formula. The infusion formula specific to the identified coffee bean species is recalled from a local memory of the infusion formula or from a remote database. The identification of the kind of coffee beans can be achieved by means of a marking applied to the package.

US 2014/0263780 a1 shows a computer implemented method for controlling the brewing of a coffee beverage based on a computer readable medium.

Also US 2018/0000108 a1 and WO 2018/053436 a1 may be mentioned in relation to the prior art of automatic brewing methods for making hot beverages.

In the coffee preparation device according to DE 102016107834 a1 with the function of roasting coffee beans, the possibility exists of controlling the roasting device, the grinding device and the extraction device by means of a control device. This can be done based on external control information. The coffee making apparatus is capable of receiving external control information. RFID reading devices may be used in this regard.

Disclosure of Invention

Starting from the foregoing, the object of the invention is to provide a method and a suitable device for treating a granular grinding material or a mixture of grinding materials by means of controlled mechanical comminution by means of a grinding mill or a combination of a plurality of grinding mills, which method or device ensures: the grinding process is carried out in an optimized manner, to be precise by means of data which are preset externally or are associated with the grinding stock. Incorrect particle sizes and incorrect treatment of the grinding stock in the form of inadmissibly high-temperature heating or other damage to the grinding stock or grinding stock mixture can thereby be avoided.

The millbase is in particular a dry, granulated millbase, such as seeds, beans, cereals or spices. However, the teaching of the invention is not limited to this millbase in principle. The use in the context of oil-containing grinding stock is likewise conceivable, in which case the corresponding grinding mill according to the known prior art can be adapted or selected in connection therewith.

The object of the invention is achieved by a method according to the teaching of claim 1 and by a device with the aid of a combination of features according to claim 9, the dependent claims including at least suitable embodiments and refinements.

The method or the proposed device is preferably used for grinding granular grinding stock, such as grains, in small quantities for domestic and catering purposes.

The device for milling uses a known mill and is capable of wirelessly reading data from a data carrier, for example an RFID chip. Furthermore, the device has the possibility of using a WLAN, GSM, UMTS or other radio network in order to transmit data specific to the milling process to the cloud, but also to download data from the cloud.

An RFID reading unit is provided for identifying the packaged grinding stock or grinding stock mixture obtained. In this regard, in one embodiment of the invention, the packaging of the grinding stock, for example the packaging bag, can have an RFID chip or a similar information carrier.

The RFID chip contains data about the grinding stock and its processing, so that automatic control of the device is possible with regard to grinding duration, grinding fineness, etc. Data regarding the milling process, as well as the milling process itself permit and data regarding the manufacturer and/or seller of the milled material, may be transmitted to the cloud. On the basis of the data obtained and read, statistical analyses and settlements in the sense of approval (Linzenz) can be carried out with respect to the grinding stock obtained and ground, which has already been processed with the corresponding apparatus.

Thereafter, the respective grinding stock or the respective grinding stock mixture, which is formulated according to the formulation, is packaged in portions. Furthermore, first data for controlling the milling process as a function of the properties of the milling stock and/or the formulation relating to the milling stock mixture are stored.

In addition, second data relating to the manufacturer and/or seller of the grinding stock or grinding stock mixture are stored. In addition, third data relating to the source and/or the properties and/or the latest service or shelf life information of the grinding stock or grinding stock mixture are stored.

The data storage unit is mounted on, introduced into, applied to or connected to the packaging, is machine-readable, in particular optically or via a radio interface.

It is recalled that when a package arrives in the vicinity of the grinding mill or of said apparatus equipped with a grinding mill, the latter is automatically activated by means of a grinding mill control unit, which is able to read the respective data storage unit of the respective package.

Mechanical crushing of the abrasive is then carried out based on the read data. At this time, the first data is used while checking the material according to the third data.

The milling process is then automatically ended. At this point, a completion report is made, wherein the control unit records the corresponding milling process in the read-write memory using the second data.

The data stored in the read-write memory are designed to be retrievable via an interface and to be made available for statistical investigations and/or commercial, in particular license-based settlement.

The data of the call is transmitted to the central server via the internet.

As the packs are supplied to the grinding mill, it is possible to automatically open the packs in such a way that the amount of grinding stock to be supplied per unit of time is determined using the first data and, for this purpose, the opening size of the packs is predefined.

In one embodiment of the invention, the mill control unit is connected to an input device for manually influencing the milling process.

Furthermore, the first to third data can be visualized by means of a display, by means of which the course and the respective state of the milling process can also be displayed.

Faults, maintenance prompts and information about the third data may also be displayed to the user via the display.

The starting point of the device according to the invention for processing a granulated grinding material or grinding material mixture by means of controlled mechanical comminution by means of a grinding mill or a combination of grinding mills is that at least one grinding mill is located in a housing, in or on which a grinding material addition container and a grinding mill control unit are arranged. The mill control unit has a first interface for wirelessly reading in data from an external data memory.

Furthermore, a second interface for connection to a WLAN, a telecommunications network or the like is formed in order to transmit data to an external server.

The device also has an operating and display unit for manually inputting data and for data display and/or function display.

By means of the WLAN interface mentioned and also the possibility of a bluetooth connection being established with the mobile communication device, the milling process can be evaluated individually, the recipe can be collected, the milling stock can be evaluated or the like by means of application software that can be installed on the communication device.

In a preferred embodiment of the invention, the device for the targeted formation of the openings in the grinding stock packaging is formed on or in the grinding stock addition funnel. Such forming of the opening can involve a mechanical cutting unit which uses data specific to the recipe or the mill stock to define the opening size, so that only the amount of mill stock that can be processed per unit time passes from the package via the addition funnel into the mill, ensuring the desired quality.

In an alternative embodiment of the apparatus, the respective packaging structure is supplied to the grinding hopper in its entirety with its contents. In this embodiment, an adjustable aperture similar to an iris is present at the end of the outlet side of the associated funnel in order to control the supply flow of the grinding stock or of the respective grinding stock mixture depending on the grinding stock properties in this connection.

The device according to the invention in combination with the proposed method achieves a particularly easy-to-use solution for the comminution of granular grinding stock, wherein the success of the grinding and thus the quality of the grinding stock to be processed is ensured. The invention also avoids incorrect handling, such as processing of unsuitable or shelf-life-exceeding millbase.

In the case of a drive of the one or more mill motors, according to the invention, it is possible to record the milling process by detecting the respective effective power of the one or more mill motors.

If it is established that deviations from the predefined setpoint data, i.e. abnormal power peaks, are recorded, an abnormal milling operation can be concluded. Thus, for example, it can be recognized that the grinding stock has foreign matter or that there is a fault in the grinding mill itself. If, for example, metal foreign bodies enter the grinding stock during the supply and packaging of the grinding stock, this can be recognized and prevented from further use, in particular eating of the comminuted grinding stock, if an evaluation of the power measurement data is concerned. The same applies to the case where, for example, in a disc mill, pieces (of the grinding disc) enter the comminuted material.
