Patent ID: 8007850

Claim:
A method for making a powder containing crystalline particles of glucopyranosyl-alditols, comprising: preparing a mixture consisting essentially of glucopyranosyl-alditol syrup, germs containing glucopyranosyl-alditols and (glucopyranosyl-alditol)-based granules by continuous mixing of the glucopyranosyl-alditol syrup having a dry matter content of at least 80% by weight and a glucopyranosyl-alditol content of at least 95% by weight, based on dry matter, the mixing being carried out by simultaneously dispersing the glucopyranosyl-alditol syrup and the germs containing glucopyranosyl-alditols in an open rotary container containing the (glucopyranosyl-alditol)-based granules, whereby the glucopyranosyl-alditol syrup and the germs containing glucopyranosyl-alditols are mixed at a surface of the (glucopyranosyl-alditol)-based granules contained in the container; recovering the (glucopyranosyl-alditol)-based granules from the container; and crystallizing the glucopyranosyl-alditols contained in said granules, the (glucopyranosyl-alditol)-based granules in the container being kept in motion by rotating the container.
