A continuous coating process for chewing gum and bubble gum materials. Smallcores or pieces of gum material are introduced into inclined rotating drums inwhich heated air is circulated and a coating solution is applied (liquid orpowder). The coating material is dried on the pieces of material, and aplurality of thin layers are formed on each of the cores or small pieces ofmaterial. A series of rotating drums can be provided to provide the requisitenumber or thickness of coating layers. In an alternate embodiment, initialcoatings of material can be provided on the cores by a batch-type processbefore the materials are introduced into the continuous coating drums. Theformulas for the coating solution can also be adjusted at different stages ofthe coating process in order to provide a more consistent and uniform coating.
