Abstract
A method for producing a powder containing xylitol crystal particles and another polyol including 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. The method includes: obtaining the mixture by simultaneously dispersing the xylitol and the other polyol syrup and xylitol-containing germs in an open rotating vessel containing xylitol-based granules, mixing the xylitol and the other polyol syrup and xylitol-containing germs on the surface of the xylitol-containing germs contained in the vessel, removing the xylitol-based granules and the other polyol from the vessel and crystallizing the xylitol and other polyol contained in the granules.
