Abstract
Abstract Process for hard coating with sorbitol. On the one hand, a sorbitol syrup having a concentration of 60 to 85% by weight is supplied on a moving bed of cores to be coated and, on the other hand, the temperature prevailing in the bed is kept at a value comprised between 50° and 10° C. The present coating process applies conveniently to cores of the "without sugar" type in the field of confectionery and pharmaceutical products.

Total Claims: 23
Claim 1
Independent Claim
121 words
Process for hard coating with sorbitol of cores of confectionery and pharmaceutical products, comprising: applying the sorbitol by addition, on a moving bed of cores to be coated, of a syrup having a concentration of dry matter comprised between 60 and 85% by weight and a richness in D-sorbitol higher than 80%, maintaining the temperature existing in the moving bed of cores to be coated at a value below 55° C., selecting these conditions within the limits indicated in such a way that, when the sorbitol syrup arrives in contact with the cores to be coated, that is to say at the temperature maintained in the moving bed, the said sorbitol is at a saturation level comprised between 0.65 and 1.25.
Claim 2
