Title
(EN) METHOD OF CONTINUOUS EXTRACTION OF CRUDE WAX AND APPARATUS THEREFOR
(FR) PROCEDE ET DISPOSITIF D'EXTRACTION CONTINUE DE CIRE BRUTE
Abstract
(EN)
A method of continuous solvent extraction of waxes contained in the solid residue separated from squeezed sugar cane juices at a high extraction efficiency in a substantially uniform extraction time, which method comprises mixing the solid residue with an organic extractant under shear and conducting the extraction under the flow condition where a sufficient kneading is effected in a direction perpendicular to the direction of flow while substantially a plug flow is formed in the direction of flow.
(FR)
Procédé d'extraction continue au solvant de cires contenues dans les résidus solides séparés de jus de canne à sucre pressée. Ce procédé présente une efficacité d'extraction élevée en un temps d'extraction sensiblement uniforme et consiste à mélanger les résidus solides avec un agent d'extraction organique dans des conditions de cisaillement et à effectuer l'extraction dans des conditions d'écoulement, un malaxage suffisant étant effectué dans un sens perpendiculaire au sens de l'écoulement, tandis qu'un écoulement sensiblement idéal se constitue dans le sens de l'écoulement.
