Abstract

Un procédé et un dispositif sont utilisés pour prélever des échantillons de mesure dans un courant de matières en vrac, en particuler des denrées alimentaires et du fourrage, afin de déterminer des valeurs caractéristiques telles que la teneur en protéines, l'humidité, la couleur, les cendres, la granulation, etc. Au moins un premier courant partiel est dérivé du courant de matières en vrac et au moins ce courant partiel rejoint le courant de matières en vrac. Le premier courant partiel ou un autre courant partiel dérivé du premier est au moins temporairement endigué, un petit pourcentage du courant partiel endigué est prélevé au moins en partie en continu comme échantillon de mesure, puis cet échantillon de mesure est conduit à travers un dispositif de mesure, de préférence par résonance magnétique ou ionique nucléaire, afin de déterminer les valeurs caractéristiques des matières en vrac.
