System for treating food products and corresponding method

A method for controlling processing of a food product, comprising the following steps:

• providing:
• a machine comprising:
• a first container configured for receiving and processing a liquid or semi-liquid base product into the food product;
• a stirrer positioned inside the first container for mixing the food product contained in the first container;
• a thermal system comprising a heat exchanger thermally connected with the first container, a further heat exchanger, a compressor, and a pressure reducing unit;
• a drive unit connected to the stirrer and configured for rotatably driving the stirrer;
• a dispenser connected to the first container and configured to allow the food product to be extracted from the first container;
• a temperature sensor adapted to detect a temperature inside the first container;
• a processing and control unit, operatively connected to the temperature sensor to receive the detected temperature and comprising a receiving and transmitting module for receiving and transmitting the detected temperature;
• a user interface comprising a user-activable control and connected to the processing and control unit, the user interface comprising at least one chosen from user-activable activation and selection controls, and pushbuttons;
• a plurality of processing nodes defining an information write module configured to write information to a distributed ledger architecture database, the information indicating the detected temperature received from the receiving and transmitting module;
• a memory containing data which indicates a set of temperature intervals conforming to one or more standards according to HACCP procedures;
• wherein the processing and control unit is configured to extract one or more temperature intervals from the set of temperature intervals, chosen as a function of a state and settings of the machine, and to check whether the detected temperature received from the temperature sensor falls within the one or more intervals extracted, and, if the detected temperature is outside the one or more intervals extracted, to generate an alarm message;
• detecting the detected temperature inside the first container with the temperature sensor;
• transmitting, through the receiving and transmitting module, the detected temperature;
• and
• writing, through the plurality of processing nodes, the detected temperature received from the receiving and transmitting module to the distributed ledger architecture database.
