System for producing a plurality of types of food products, which differ from each other, for example, in their shape and/or their composition, particularly chocolate-based products and the like, comprising: a plurality of moulds having each a plurality of housings adapted to form correspondingly moulded products; a conveyor for conveying in sequence a plurality of said moulds along a predetermined production path on which is located a plurality of stations (S1-S16), each of which can execute at least one corresponding operation; each mould carrying a corresponding electronic identification device including memory devices from and to which information or data can be read and written without contact, by means of an associated antenna or the like; each station (S1-S16) being provided with at least one corresponding electronic unit (A-E) including a processor, having associated memory devices and at least one antenna or the like, and designed to read and/or write information or data from or to the memory devices of a mould passing through the station (S1-S16); the system comprising at least one initial input station, and at least one intermediate station (S3, S6,...) adapted to be controlled selectively in a plurality of predetermined modes for the forming of a corresponding plurality of different product types in the housings of said moulds, the electronic unit of this station being capable of selectively modifying the mode of execution of at least one of its operations, in accordance with operating information read from the memory devices associated with each mould passing therethrough; and the electronic unit of said initial input station being designed to transfer or write to the memory devices of each mould passing therethrough operating information identifying the products to be formed in the mould and relating to the corresponding forming operations, the system being characterised in that at least some of the moulds allow different products to be formed in predetermined specific areas thereof, and in that said input station is adapted to transcribe into the memory devices associated with said at least some moulds information indicating the specific products to be formed in each of said areas and the corresponding forming operations. a plurality of moulds having each a plurality of housings adapted to form correspondingly moulded products; a conveyor for conveying in sequence a plurality of said moulds along a predetermined production path on which is located a plurality of stations (S1-S16), each of which can execute at least one corresponding operation; each mould carrying a corresponding electronic identification device including memory devices from and to which information or data can be read and written without contact, by means of an associated antenna or the like; each station (S1-S16) being provided with at least one corresponding electronic unit (A-E) including a processor, having associated memory devices and at least one antenna or the like, and designed to read and/or write information or data from or to the memory devices of a mould passing through the station (S1-S16); the system comprising at least one initial input station, and at least one intermediate station (S3, S6,...) adapted to be controlled selectively in a plurality of predetermined modes for the forming of a corresponding plurality of different product types in the housings of said moulds, the electronic unit of this station being capable of selectively modifying the mode of execution of at least one of its operations, in accordance with operating information read from the memory devices associated with each mould passing therethrough; and the electronic unit of said initial input station being designed to transfer or write to the memory devices of each mould passing therethrough operating information identifying the products to be formed in the mould and relating to the corresponding forming operations, the system being characterised in that at least some of the moulds allow different products to be formed in predetermined specific areas thereof, and in that said input station is adapted to transcribe into the memory devices associated with said at least some moulds information indicating the specific products to be formed in each of said areas and the corresponding forming operations.
