Abstract

The invention relates to a roasting and grinding apparatus for coffee beans comprising a roasting device ( 50 ) and an associated grinding device ( 60 ); the roasting device ( 50 ) being configured for receiving coffee beans of a certain type that will be roasted, the roasting device ( 50 ) comprising reading means ( 53 ) to identify the characteristics of the coffee beans dispensed to it, the roasting device ( 50 ) further comprising a control unit configuring the roasting profile of the beans according to the characteristics retrieved from the reading means ( 53 ) and/or from the characteristics of the beans in a database ( 51 ) in this control unit and/or according to the user's input; the roasted coffee beans being dispensed into a beans container ( 10, 20 ), the beans container ( 10, 20 ) comprising programmable identification means where product parameters of the roasted coffee beans of a certain type are encoded on it by an encoder ( 52 ) in the roasting device; the grinding device ( 60 ) comprising one or more housings for receiving one or more beans containers ( 10, 20 ); the grinding device ( 60 ) comprising a reader ( 62 ) to obtain the information of the product parameters of the roasted coffee beans of the one or more beans containers ( 10, 20 ); the grinding device ( 60 ) further comprising a control unit configured to adapt the grinding size and the quantity of roasted coffee beans to be delivered from the coffee beans containers ( 10, 20 ) for obtaining a certain coffee quantity and/or a certain coffee blend quantity from each beans container to be grinded according to these product parameters and/or according to a recipes database ( 64 ), and/or according to the user's input. The invention further relates to a method for roasting and grinding coffee beans using a roasting and grinding apparatus as the ones described, and to the use of such a roasting and grinding apparatus.

First claim

The invention claimed is:

1. A roasting and grinding system for coffee beans comprising:
a roasting device configured for receiving coffee beans from a first container and roasting the coffee beans, the roasting device comprising a first reader configured to read an optical or electromagnetically readable code of the first container to identify a characteristics of the coffee beans, the roasting device further comprising a roasting device control unit to configure a roasting profile of the coffee beans, wherein the roasting profile is configured according to;
(a) the characteristics identified by the first reader,
(b) an additional characteristics of the coffee beans in a database in the roasting device control unit,
(c) a user input, or
(d) any combination of (a), (b), and/or (c),

wherein the roasting device is further configured to dispense roasted coffee beans into one or more beans containers, wherein the roasting device further comprises an encoder configured to encode a product parameter of the roasted coffee beans on a programmable identification means of the one or more beans containers;
the one or more beans containers configured to receive the roasted coffee beans from the roasting device, wherein the one or more beans containers comprise the programmable identification means;
a grinding device comprising one or more housings for receiving the one or more beans containers, the grinding device comprising a second reader to obtain the product parameter of the roasted coffee beans from the programmable identification means of the one or more beans containers, the grinding device further comprising a grinding device control unit configured to adapt a grinding size and a quantity of roasted coffee beans to be delivered from the one or more beans containers for obtaining a certain coffee quantity and/or a certain coffee blend quantity from each of the one or more beans containers to be grinded according to:
(e) the product parameters,
(f) a recipes database,
(g) an additional user input, or
(h) any combination of (e), (f), and/or (g).

2. The system of claim 1 wherein the characteristics of the coffee beans is selected from the group consisting of: coffee beans type, coffee beans origin, batch volume, recommended roasting level or levels, date of harvest, date of production, production data, farmer data, date of expiration, company and marketing info, and combinations thereof.

3. The system of claim 1 wherein the coffee beans are green before being roasted by the roasting device.

4. The system of claim 1 wherein the optical or electromagnetically readable code of the first container comprises an OID, a barcode, a QR code, a RFID tag, or a combination thereof.

5. The system of claim 1 wherein the product parameter comprises the characteristics of the coffee beans and one or a plurality of the following: roasting level, roasting profile, CTn, aroma profile chart, adequate beverage recommendation, roasting date, best limit consumption date.

6. The system of claim 1 wherein the programmable identification means comprises a RFID tag.

7. The system of claim 1 , wherein the quantity of the roasted coffee beans to be grinded, the grinding size and the blend in the grinding device are adapted as a function of the type of beverage to be prepared from the roasted and grinded coffee beans in combination with the product parameters of the roasted coffee beans of obtained from the programmable identification means of the one or more beans containers connected to the grinding device.

8. The system of claim 1 wherein the one or more beans containers have an embedded doser to dose a dose of roasted coffee beans in the grinding device.

9. The system of claim 8 wherein the grinding device comprises a motor and a drive to control the embedded doser of the one or more beans containers to dose the dose of roasted coffee beans to the grinding device.

10. The system of claim 1 wherein the one or more beans containers comprise a plug to be plugged onto the grinding device so that the one or more beans containers are freely exchangeable.

11. The system of claim 10 wherein the one or more beans containers are lockable on top of the grinding device to allow the one or more beans containers to be fixed during the grinding operation.

12. The system of claim 10 wherein the plug is selected from the group consisting of: bayonet connection, magnetic connection, electromagnetic connection, and clutch system.

13. The system of claim 1 wherein the encoder comprises a RFID tag encoder.

14. The system of claim 1 wherein the second reader comprises a RFID tag reader.

15. A method for roasting and grinding coffee beans using a roasting and grinding system comprising the following steps:
dispensing a quantity of coffee beans from a first container into a roasting device comprising a first reader;
reading an optical or electromagnetically readable code of the first container using the first reader to identify a characteristics of the coffee beans dispensed into the roasting device;
carrying out a roasting process according to: (a) the characteristic identified using the first reader, (b) a database information, (c) a user's choice or selection, or (d) any combination of (a), (b), and/or (c);
delivering the roasted coffee beans into a beans container;
encoding a product parameters into a programmable identification means of the beans container using an encoder of the roasting device;
attaching the beans container into a grinding device;
