Method for Producing a Powder Containing Xylitol Crystal Particles with Another Polyol

A method for manufacturing a powder containing crystalline particles of xylitol and of another polyol, comprising the continuous mixing of a syrup of xylitol and of another polyol, having a solids content of at least 95 wt %, having a xylitol content of 85 to 97.5 wt % and a content of the other polyol of at least 15 to 2.5 wt % based on the solids content, said mixing being carried out by simultaneously dispersing the syrup of xylitol and of the other polyol with seeds containing xylitol in an open rotary container that contains xylitol-based granules, with which the syrup of xylitol and of the other polyol and the seeds containing xylitol are mixed at the surface of the xylitol-based granules contained in the container, the recovery of the granules based on xylitol and on the other polyol from the container, and the crystallization of the xylitol and of the other polyol contained in said granules, the granules based on xylitol and on the other polyol in the container being kept moving by the rotation of the container.
