Abstract

Cette invention concerne une méthode de dosage de l'alimentation en produit détergent d'une machine à laver industrielle qui fait appel à la détermination d'une propriété de l'eau de lavage fonction de la concentration de détergent dans l'eau et qui commande l'ajout de détergent lorsque la valeur de la propriété mesurée correspond à une concentration de détergent inférieure à une valeur de consigne, la propriété mesurée étant la conductivité électrique de l'eau de lavage et l'instrument de mesure, une cellule comportant une ou plusieurs électrodes (3, 4). La méthode comporte une étape a) d'ajout à l'eau fraîche de remplissage initial de la machine d'une quantité de détergent propre à réaliser la concentration de consigne, suivi du brassage de l'eau additionnée de détergent; une étape b) de mesurage de la conductivité de la liqueur de lavage après moins de deux minutes de brassage et une étape c) d'entrée de la valeur de conductivité mesurée et de la concentration de détergent correspondante dans la mémoire d'un contrôleur (1) pour servir de valeurs de consigne en fonction desquelles régler l'ajout de détergent au besoin.
