Abstract
La présente invention concerne un procédé d'extraction à partir d'un stock en vrac. Le procédé selon l'invention consiste à mettre en oeuvre trois surfaces perforées les unes sur les autres, mises en mouvements relatifs les unes par rapport aux autres de telle manière que le produit provenant d'un stock de vrac contenu dans une trémie soit, par les mouvements relatifs desdites surfaces, extrait en quantités précises. Le procédé selon l'invention et les dispositifs de mise en oeuvre sont particulièrement applicables à l'extraction des produits pulvérulents colorants.
