Abstract: 1. A method for optimising process management and process control in an arrangement for producing, especially short and long, farinaceous products in which dough is kneaded intensively in a mixing kneader and farinaceous pre products leaving a press head in the form of damply and platelet test braids are fed to final drying via differently heated and/or moist climatic zones and cooled and stabilized in shape with a final moisture content of at least 14%, automatic, self-controlling product quality regulation is to be used by means of intelligent software technologies and on-line sensors for producing farinaceous products, characterized in that the process control is performed in all production steps by recording product moisture and/or farinaceous products weight loss in real time and between process parameters and product properties setting up models using statistical and intelligent software technologies, comprising, at least, one of the following means: neural network, fuzzy system, expert system, analytical models, the first data of recipe values are input for specific product properties as a target value, optimize initial values when the process is started. modeling interrelation between deviation of the target value and change of adjustable value, which is a climatic characteristic in a drier, and regulate said climatic characteristic according to modeled interrelation. 2. The method according to claim 1, characterized in that the predetermined optimum characteristics of the product moisture and drying characteristics are controlled. 3. The method according to any one of claims 1-2, characterized in that hybrid model is used for modeling, optimizing and regulating. 4. The method according to claim 3, characterized in that the hybrid models use combinations of technologies given in claim 1. 5. The method according to any one of claims 1-4, characterized in that genetic algorithms or other optimization algorithms are used for modeling, optimizing and regulating. 6. The method according to claim 1, characterized in that virtual sensors are used instead of on-line sensors. 7. The method according to claim 6, characterized in that a press for producing farinaceous products is used as a virtual sensor of product properties such as moisture content and dough consistency. 8. The method according to any one of claims 1-7, characterized in that first receipt data valued are input when new products are introduced. 9. A device for optimizing process management and process control in an arrangement for producing, especially short and long, farinaceous products comprising a dosing unit (1), a mixing kneader (2), a press head (3), a dryer/cooler (5,6,7,8), on-line sensors (9) for recording weight loss and moisture content of farinaceous products are provided in the press head (3), dryer (5,6,7) and cooler (8), wherein a diffuser (4) is provided working, at least, with one on-line sensor (9), characterized in that said on-line sensors are connected to the process control means. 10. The device according to claim 9, characterized in that the process control means is means for regulating the automatic correction of process management in real time.
