Definitions

  • the invention relates to a method for optimizing process control and process monitoring in a system for producing pasta, in particular short and long pasta, and to an apparatus for carrying out the method
  • EP-A-0 129 892 B1 describes a system and a method for drying pasta long pasta in continuous operation with controlled heating, humidification, drying and cooling of the pasta. A temperature-time regime in a turbo system is specified.
  • EP-A-0 540 699 B1 describes a further method for regulating the product moisture in order to break the pasta after drying and to be avoided when packing, temperature and humidity are regulated.This is done in the end zone of drying while the pasta is still warm, a further superficial addition of water and the temperature of the pasta is reduced to below 60 ° C immediately after the addition of water
  • the EP teaches the use of an AW value - A-0 322 053 B1.
  • Automated presses for the production of raw pasta are, for example, EP-A-0 426 766 B1 in the form of a mixing kneader which contains two working shafts which alternate between kneading screws and shear elements or DE-44 17 357 A1
  • DE-44 33 593 A1 shows a method for controlling an extruder, target values of a control system being created on the basis of test data or expert knowledge, the manipulated variables of which depend on the product quality.
  • This controller can be a process-regulating fuzzy controller.
  • controls for specific controlled systems are automatically adapted and specific controllers are generated. The latter using code generators that are integrated into the control environment.
  • an in-line viscosity sensor is installed between the nozzle and the screw tip of the extruder.
  • DE-197 34 71 1 C1 describes a controller with discrete-time, dynamic fuzzy control elements, in which nonlinearities can be introduced specifically for a desired control behavior.
  • the invention is based on the object of developing an optimization of the process control of individual sub-processes in a plant for the production of pasta, in particular short and long pasta or the like, which improves press and dryer control and process monitoring with the use of intelligent software Technologies. In particular, a simpler controller setting and a reduction in incorrect production should be achieved.
  • the problem is solved on the basis of the features of claim 1.
  • This problem is solved with the features of claim 1, by using intelligent software technologies such as a virtual sensor (also "soft sensor") for the end product moisture, with a regulation of the amount of dosing water in the press Keeping the permissible limits
  • intelligent software technologies such as a virtual sensor (also "soft sensor") for the end product moisture, with a regulation of the amount of dosing water in the press Keeping the permissible limits
  • climate sensors and product moisture curves can also be controlled using online sensors in the dryer for product moisture measurement and / or weight loss measurement
  • the invention is based on the knowledge that the individual sub-processes depend on one another and that point-by-point optimization is not very promising.
  • the interaction between product properties and machine behavior is the basis.
  • Models between the process parameters (machine settings, raw materials, recipe mixtures) and product properties (e.g. B moisture content, color, viscosity) created using statistical and intelligent software technologies
  • Intelligent software technologies include technologies such as expert systems, neural networks, fuzzy logic and genetic algorithms (evolutionary algorithms). These are described, for example, in the article “Soft Computing in Automation” by P Auer, Elektronik 34/1998
  • hybrid models are created which take into account both the existing expert knowledge (e.g. with fuzzy rules) and experimental data (which e.g. are generated by means of statistical test planning and process tests and are modeled in neural networks)
  • these models are combined with conventional, analytical models (e.g. based on physical models or regression calculation) and are also referred to as hybrid
  • Another object is then to create a device for performing the method
  • the online control enables the criteria for the final quality of the products to be kept constant over the long term during production and also in the event of process faults.
  • the product-related control variables are regulated (eg product moisture) Every standard size should be measurable and stubborn sizes should be reduced.
  • the room climate should be included in the online control of the climate of individual dryer zones, and if necessary also in product ventilation.
  • the pasta press can also be used as a virtual sensor for product properties such as Dough moisture and dough consistency can be used
  • a recipe wizard automatically gives a first indication of the recipe values required for the specific, desired product properties.Recipe start values are generated from product specifications.Learning data, expert knowledge and physical conditions are used to model and calculate the recipe values from the specifications are sufficiently similar for the new product specifications
  • a subsequent recipe optimization supports the fine adjustment of the first recipe information and a diagnosis can be used to identify and distinguish gross errors, whereby the operator should receive information on which errors he should check and remedy
  • the initial values are optimized when the recipe is run in and relationships between the target size deviation and the setting size change are modeled.
  • the operator can set the target parameters to a desired value and new setting sizes can be set automatically. Manual adjustments are also possible
  • FIG. 1 shows the schematic sequence in a pasta press device and FIG. 2 shows the schematic sequence in a dryer / cooler
  • the raw materials pass from a metering unit 1, in which powder and / or flour and water and additives are metered and mixed, into a mixing kneader 2, for example in accordance with EP-A-0 426 766 B1, where intensive mixing and kneading of the raw materials takes place to a raw dough
  • a mixing kneader 2 for example in accordance with EP-A-0 426 766 B1, where intensive mixing and kneading of the raw materials takes place to a raw dough
  • the raw dough reaches a press screw 3 of the mixing kneader 2, by means of which the raw pasta is produced.
  • a diffuser 4 follows
  • the wet raw pasta with a moisture content of approx. 30% then passes into a tumble dryer 5 and then into the pre-dryer 6 and final dryer 7 and cooler 8, in which a drying process is carried out in accordance with EP-A-129892 and / or EP-A-540699
  • the pasta leaves the cooler with a usual product moisture content of 1 1 -13%, preferably 12.5%.
  • the dry pasta is then cut and packaged in the usual way
  • the resulting climate control makes it possible to keep the product moisture very close to the optimal 12.5% and ultimately to significantly reduce the faulty production while maintaining the quality of the pasta
