DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] This disclosure therefore refers to a machine 1 for treating food products. Machine 1 may include any machine for treating / processing food products. However, in the following, for the sake of simplicity and ease of understanding, and without loss of generality, machine 1 will be described as a machine adapted to (thermally) treat liquid or semi-liquid products, suitable for carrying out a thermal treatment such as pasteurization, or as a machine for making ice cream products.

[0009] The machine 1 for producing liquid or semi-liquid products shown in FIG. 1 is preferably adapted to produce ice cream (handmade gelato or soft serve ice cream) or other products of the ice cream industry (granita, sorbet, etc.), confectionery, etc. (milkshakes, yogurt, frozen desserts, chilled dessert creams, as non-limiting examples).

[0010] The machine 1 for producing liquid or semi-liquid food products is a first processing container 2 for processing the food product and defining a processing chamber 3 (e.g. a first container 2 for processing a liquid or semi-liquid based product); one or more temperature sensors 50 adapted to detect the temperature within the container 2; and a processing and control unit 7 operatively connected to the one or more temperature sensors 50 to receive the detected temperatures.

[0011] process and control The unit 7 is preferably a HW element (or is defined by a number of interconnected HW elements).

[0012] The processing and control unit 7 also comprises a module for transmitting and receiving data 8 (coupled to the sensor 50) for transmitting at least the detected temperature.

[0013] The module 8 for transmitting and receiving data preferably comprises a data communication interface.

[0014] Preferably, the module 8 for transmitting and receiving data is configured for connection to the Internet network.

[0015] Preferably, the machine 1 comprises an agitator 4 (preferably located inside the first processing vessel 2) for mixing the product contained in the first processing vessel 2.

[0016] Preferably, the machine 1 comprises a thermal system 5 including a heat exchanger 6 associated with the first processing vessel 2 .

[0017] As shown in the attached figures, the machine 1 comprises a drive unit connected to the agitator 4 for driving the latter in rotation.

[0018] Preferably, the drive unit is connected to a processing and control unit 7 .

[0019] According to another embodiment, the thermal system 5 comprises a heat exchanger 6 associated with the first processing vessel 2 (as described above), a further heat exchanger 20 , a compressor 21 and a pressure reduction unit 22 .

[0020] It is noted that the heat exchanger 6, the further heat exchanger 20, the compressor 21 and the pressure reduction unit 22 define a circuit containing a heat exchanger fluid.

[0021] In other words, the thermal system 5 is a thermodynamic system (configured to operate according to a thermodynamic cycle using a heat exchanger fluid).

[0022] The thermal system 5 is configured to cool and / or heat the product in the first container 2 .

[0023] According to another embodiment, the machine 1 comprises a user interface 13 including at least one user-activatable control (preferably a plurality of controls) and connected to the processing and control unit 7. Preferably, the interface 13 includes user-activatable activation and selection controls and / or push buttons.

[0024] According to yet another embodiment, the machine 1 comprises a dispenser 14. The dispenser is connected to a first processing vessel 2 for processing a liquid or semi-liquid base product and makes it possible to extract the product from the vessel 2.

[0025] The dispenser 14 preferably includes a user-actuable lever to enable dispensing of a liquid or semi-liquid base product.

[0026] The machine 1 forms part of a system 100 for processing food products.

[0027] In addition to the machine 1, the system includes a number of processing nodes 16 defining an information writing module 80 configured to write, in response to the data received from the transceiver module 8, information indicative of at least the temperature received from the transceiver module 8 into a distributed ledger-type distributed architecture database DB.

[0028] In fact, according to one embodiment, these processing nodes are also storage nodes of the distributed ledger-based distributed architecture database DB. Thus, information received from the data transceiver module 8 can be stored in these storage nodes of the distributed ledger-based distributed architecture database DB.

[0029] According to another aspect, the distributed architecture database DB is of the blockchain ledger type and contains information grouped into a number of interconnected blocks (B1, B2, Bn), each of which is associated with a timestamp such that each temperature written in the database DB is authenticated by the timestamp.

[0030] According to one aspect of the present invention, the distributed ledger type distributed architecture database DB may be an authenticated electronic register.

[0031] "Authenticated" (with respect to electronic registers) means that the data stored in the distributed ledger-based distributed architecture database DB (e.g. temperature linked to a timestamp) is protected by the database so that unregistered and / or unauthorised tampering or changes to the data are not possible. In this way, information on the storage / processing of products can be obtained with the assurance that each retrieved data item is identical to the data item originally stored, since the data cannot be modified after it has been stored in the database.

[0032] In this sense, the use of a distributed architecture database guarantees transparency, reliability and security of the data stored in the database DB.

[0033] Preferably, the database DB is at least partially accessible between one or more of the following: the manufacturer of the machine 1, the manufacturer of the food product of the machine 1, and / or the end user of the machine.

[0036] The processing and control unit 7 may be a distributed unit, ie a unit with distributed HW and SW elements, or it may be a single unit.

[0037] According to another embodiment, the processing and control unit 7 may also define processing (storage) nodes of a distributed architecture database DB of the “blockchain” type, which contains information grouped into a number of interconnected blocks B1, B2, ... Bn.

[0042] In one or more embodiments, the processing and control unit 7 may optionally be configured to extract one or more temperature intervals from a set of temperature intervals, selected depending on the state and settings of the machine for processing food products. For example, if the machine 1 is a machine for liquid or semi-liquid products designed to perform a pasteurization process, the memory 10 may include temperature intervals including temperatures at which heat sterilization is effective. Additionally or alternatively, if the machine 1 is a device for storing food products, the memory 10 may include temperature intervals including temperatures at which correct storage can be ensured.

[0043] Further, the processing and control unit 7 may, optionally, be configured to check whether the temperature received from the sensor / sensors 50 is within the extracted interval or intervals and to generate an alarm message if the temperature is outside the extracted interval or intervals.

[0044] The alarm message may be transmitted to and displayed on the user interface 13. Additionally or alternatively, the alarm message may be transmitted to multiple processing nodes 16 along with the detected temperature.

[0045] According to an aspect of the invention, the machine 1 may optionally be equipped with a code reader (e.g. a QR code reader or a barcode reader). The reader may be configured to scan a code associated with a food product placed on the machine 1. A module 8 of the processing and control unit 7 (coupled to the code reader) may be configured to transmit the information read by the code reader to an information writing module 80 configured to write the information in the distributed database DB. It is thus possible to automatically store information related to the entry of a new product, associated with an authenticated timestamp, in the database.

[0048] In this manner, the second set of processing nodes may advantageously incorporate simpler and less memory than the first set of processing nodes.

[0049] Preferably, each information block of the plurality of blocks B1, B2, Bn has a time stamp associated with it.

[0050] According to one embodiment, the processing nodes are configured to define nodes of a distributed architecture database operating with a (consensus) protocol that is of one of the following types: - Proof of Work, - Proof of Stake, - The Corda consensus protocol (designed to reach consensus on certain "state objects"); - Crash-fault-tolerant (CFT), preferably implemented with Kafka and / or Zookeeper; - Solo, - BFT (Byzantine Fault Tolerance), - PBFT (Practical Byzantine Fault Tolerance), - SBFT (Simple Byzantine Fault Tolerance), - Raft, - Sumeragi, - PoET (Proof of Elapsed Time), - Permissioned or Voting-based.
