1. A hot-melt coating method, in which disperse material, dispersed in a gas or gas mixture and being provided as a fluidized bed, is coated with a coating material by spraying the disperse material with the coating material to form a product from individual surface stable parts,
characterized in that
the coating material consists of a composition with at least 98 percent by weight on one or more polyglycerol fatty acid esters each obtainable by complete or partial esterification of a linear or branched polyglycerol containing two to eight glycerol units with one or more fatty acid, each containing 6 to 22 carbon atoms, as the main constituent by weight, wherein the gas or gas mixture has a temperature during the spraying which is only 1° C. to 3° C. below the solidification temperature of the coating material.
