Abstract

L'invention concerne la détermination rapide des diverses valeurs d'une caractéristique d'une matière en cours de traitement, et l'obtention d'une valeur moyenne servant à commander l'appareillage de production de cette matière. Sur un nombre choisi d'échantillons, on effectue des mesures rapides d'une caractéristique, on identifie une valeur moyenne courante apparente que l'on traite comme étant la mesure correspondant à une distribution finale plus régulière de cette caractéristique dans la matière. Application : réglage de la teneur en humidité d'une poudre de lait.The invention relates to the rapid determination of the various values of a characteristic of a material being processed, and to obtaining an average value for controlling the equipment for the production of that material. On a chosen number of samples, rapid measurements of a characteristic are made, an apparent current mean value is identified which is treated as being the measurement corresponding to a final more regular distribution of this characteristic in the material. Application: adjustment of the moisture content of a milk powder.
