A system for extracting a liquid by pressing a humid mass, said system comprising at least one extraction channel, which extraction channel being provided with at least one inlet allowing to feed the extraction channel with the humid mass to be treated; with walls provided with holes allowing the flow of the liquid contained in the humid mass being pressed; and with at least one outlet allowing the discharge of the dehydrated mass obtained by pressing in the extraction channel, wherein said system is characterized in that the outlet of said channel, positioned between the walls provided with holes and the exterior, is free of constraints or only comprises weak constraints whose level is controlled as a function of physical parameters. This system is suitable for the efficient continuous dewatering treatment of a feeding source with a composition, consistency and nature of the solid particles present in the feeding source susceptible to vary during the processing.
L'invention concerne un système permettant d'extraire un liquide par une pression exercée sur une masse humide, ledit système comprenant au moins un canal d'extraction, lequel est pourvu d'au moins un orifice d'entrée permettant d'alimenter le canal d'extraction avec la masse humide à traiter; de parois à trous permettant au liquide contenu dans la masse humide pressée de s'écouler; et d'au moins un orifice de sortie permettant de décharger la masse déshydratée obtenue par pression dans le canal d'extraction. Le système selon l'invention se caractérise en ce que l'orifice de sortie dudit canal, disposé entre les parois à trous et l'extérieur, est exempt de contraintes ou présente seulement de faibles contraintes dont le niveau est régulé en fonction de paramètres physiques. Ce système convient pour un traitement de déshydratation continue efficace de source d'alimentation au moyen d'une composition, la consistance et la nature des particules solides présentes dans la source d'alimentation étant susceptibles de varier pendant le traitement.
