Title (EN) METHOD FOR PRODUCING A POWDER CONTAINING XYLITOL CRYSTAL PARTICLES WITH ANOTHER POLYOL
(FR) PROCEDE DE PRODUCTION D'UNE POUDRE CONTENANT DES PARTICULES CRISTALLINES DE XYLITOL AVEC UN AUTRE POLYOL
Abstract:
(EN) The invention relates to a method for producing a powder containing xylitol crystal particles and another polyol comprising a mixture containing a xylitol syrup and another polyol, whose dry material content is equal to or greater than 95 % by weight, xylitol content ranges from 85 to 97.5 % by weight and the other polyol content ranges at least from 15 to 2.5 % by weight with respects to the dry material, wherein the inventive method consists in obtaining said mixture by simultaneously dispersing the xylitol and the other polyol syrup and xylitol-containing germs in an open rotating vessel containing xylitol-based granules, in mixing the xylitol and the other polyol syrup and xylitol-containing germs on the surface of the xylitol-containing germs contained in the vessel, in removing the xylitol-based granules and the other polyol from the vessel and in crystallising the xylitol and other polyol contained in said granules, wherein the xylitol-based granules and the other polyol in the vessel are movable by the vessel rotation.
(FR) L'invention concerne un procédé, de fabrication d'une poudre contenant des particules cristallines de xylitol et d'un autre polyol, comprenant le mélange continu d'un sirop de xylitol et d'un autre polyol présentant une teneur en matière sèche d'au moins 95 % en poids, et ayant une teneur en xylitol de 85 à 97,5 % en poids et en l'autre polyol d'au moins 15 à 2,5 % en poids sur la base de la matière sèche, le mélange étant effectué en dispersant simultanément le sirop de xylitol et de l'autre polyol et des germes contenant du xylitol dans 'un récipient rotatif ouvert contenant des granulés à base de xylitol, ce par quoi le sirop de xylitol et de l'autre polyol et les germes contenant du xylitol sont mélangés à la surface des granulés à base de xylitol contenus dans le récipient, la récupération des granulés à base de xylitol et de l'autre polyol depuis le récipient et la cristallisation du xylitol et de l'autre polyol contenus dans lesdits granulés, les granulés à base de xylitol et de l'autre polyol dans le récipient étant maintenus en mouvement par la rotation du récipient .
