It becomes the mixing container steadily liquid and powdery substance, the latter either continuously or discontinuously fed, and it is continuously discharged from the mixing vessel, a mixed product according to the supplied amounts of liquid and powdered material. Stirring and / or mixing or shearing and homogenization ensure that the theoretical postulate is that the mixed product has the same composition (eg dry matter concentration) at every point and that no temperature differences occur. The dry matter concentration in the discharged mixed product remains constant over the duration of the mixing process.
  • the present invention is exclusively concerned with mixing processes, which are operated in the batch process and here in all possible forms.

Only when deviations from the permissible current exceeding or current undershooting ⁇ 1, ⁇ 2 occur, the control mechanisms, as described in the first method in connection with FIGS. 3 and 4, apply mutatis mutandis.
  • control devices 30 with a variable time-to-time ratio V require the control device 30 to be able to shorten or lengthen the duration of the metering pulse At1 with an unchanging interval of adjacent metering pulses At2 or, if the metering pulse At1 is not changed, the time interval adjacent Adequately lengthen or shorten dosing pulses At2.
  • control measures according to the invention thus consist essentially in both embodiments of the method in that the time duration of the metering pulse At1 and the time interval of adjacent metering pulses At2 are selected such that the time-dependent determined current consumption I (t) at the respective end of the time interval of adjacent metering pulses At2 Stirring and / or shearing and homogenizing of the temporarily present mixed product M * to the time-dependent course of a reference current absorption l 0 (t), which is required for the relevant treatment of the homogenized mixed product M, approximates within a practically acceptable tolerance.

Abstract

L'invention concerne un procédé pour la régulation de l'introduction d'une substance sous forme de poudre (P) dans un liquide (F) constitué par au moins un composant pour un procédé de mélange par lots selon le préambule de la revendication 1 ainsi qu'un dispositif de mélange pour la réalisation du procédé en question, qui assurent que les inconvénients de l'état de la technique rendus publics jusqu'à présent soient évités. Ce problème est résolu, d'un point de vue technique de procédé, par un premier procédé, entre autres, • en ce que l'introduction discontinue de la substance sous forme de poudre (P) a lieu par impulsions par une succession temporelle d'impulsions de dosage (i), qui sont à chaque fois caractérisées par un flux massique de la substance sous forme de poudre (ṁP), par une durée de l'impulsion de dosage (Δt1) et par un intervalle temporel entre des impulsions de dosage adjacentes (Δt2), • en ce qu'une consommation de courant dépendant du temps (l(t)) est déterminée, qui est proportionnelle à une puissance d'agitation et/ou de cisaillement et d'homogénéisation nécessaire pour un produit de mélange existant temporairement (M*) et • en ce que, à la fin de l'intervalle temporel entre des impulsions de dosage adjacentes (Δt2) et lors de la déviation de la consommation de courant en fonction du temps (l(t)) par rapport à la valeur à chaque fois associée dans l'allure en fonction du temps d'une consommation de courant de référence (lo) de plus d'une tolérance prédéfinie, et ce soit vers le haut, soit vers le bas, la durée de l'impulsion de dosage (Δt1) pour l'impulsion de dosage suivante (i) est raccourcie dans le premier cas et allongée dans le deuxième cas.
