The invention concerns a method and a device for rapid testing of the quality of cereals, grits and flours by measuring the aggregation of gluten, whereby the sample to be tested in aqueous solution/suspension containing mineral salts and/or acids and/or liquors in a specific amount in a sample cup is stirred with an electrically driven stirring paddle and the resistance opposed to the paddle by the sample during the stirring process is measured, the torque loads acting on the rotatably mounted electric drive motor being measured from the beginning of the stirring process by means of extensometric gauges, the measurement being completed once the maximum rotating torque is reached and the measuring process being monitored, controlled and analyzed by software.
L'invention concerne un procédé pour tester rapidement la qualité de céréales, de gruaux et de farines en mesurant l'agrégation du gluten, procédé selon lequel l'échantillon à tester en solution/suspension aqueuse contenant des sels minéraux et/ou des acides et/ou des lessives en quantité définie dans un godet à échantillons est agité au moyen d'une palette agitatrice à commande électrique et la résistance opposée à la palette par l'échantillon pendant le processus d'agitation est mesurée, les forces de torsion agissant sur le moteur électrique de la commande, monté de manière rotative, étant mesurées à partir du début du processus d'agitation au moyen de jauges extensométriques, la mesure étant terminée une fois le couple de rotation maximal atteint et le processus de mesure étant surveillé, piloté et analysé par un logiciel.
