Intelligent, self-adaptive control apparatus for the automated optimization and control of the grinding line of a roller system, and corresponding method

Abstract

The invention relates to a product processing installation and a corresponding method for the grinding and / or crushing of granular fruits or the like, in particular an intelligent, self-adaptive closed-loop and open-loop control method and a corresponding closed-loop and open-loop control apparatus for the self-optimised control of a mill installation and a grinding line of a roller system of themill installation. The grinding line comprises a plurality of processing units that, based on operative process parameters, are each individually actuatable by means of the closed-loop and open-loop control apparatus and have individually regulable operation. A batch controller having a defined processing sequence in the processing units is regulable by means of an operative process recipe, wherein a defined amount of an end product is producible from one or more starting materials by means of the operative process recipe. The processing units are controlled based on, specifically, operative batch process parameters associated with the operative process recipe.

Description

technical field [0001] The present invention generally relates to an intelligent adaptive regulation and control device for the automatic regulation and control of grinding systems and roller systems, in particular grinding plants with roller mills, but also mill systems and grinding plants . The invention relates in particular to regulating devices for grain mills and other equipment for the processing and comminution of cereals, in particular for comminuting, transporting, sieving and conditioning of cereals, and to Regulation and control method and regulation device for self-optimizing control and monitoring of such plants. For process monitoring (measuring, monitoring) as well as for plant or for example measurements such as moisture content, protein content, starch damage, ash content (minerals) of flour (or ground intermediate products), residual starch content, fineness of grind, etc. For the purpose of process control and / or regulation, possible applications of the d...

Problems solved by technology

It is known that the provision and automation of such control and regulation systems is complex, since a plurality of at least partially interdependent parameters, ie associated parameters, have to be taken into account (eg EP0013023B1, DE2730166A1)

The operation of the milling device is influenced by various parameters, such as by selection of the type of grain or grain mixture and growing area, harvest time, desired quality standard, specific gravity and / or moisture or grain mixture ratio of individual types of grain, air temperature, relative Air humidity, technical data of the installed elements used in the mill system and / or desired flour quality as specified process variables and selection of distances, grinding pressure, temperature and / or power intake of the motors of the grinding rollers, all The flow rate and / or moisture content of the obtained ground material and / or the quality of the flour in relation to the mixture ratio complicates the differential control of the grinding process in grain milling plants

Often enough that some of these process variables and operating process parameters are outside their tolerance ranges to have a dramatic effect on the operation of the mill

Due to this complexity of the process, despite all efforts to automate the equipment, the main miller still exists, because as a "human expert" he has to decide whether the control signal assigned to the input signal variable appears to be desired The change
