CONTINUOUS COATING OF GUM MATERIALS

摘要

A continuous coating process for chewing gum and bubble gum materials. Small cores or pieces of gum material are introduced into inclined rotating drums in which heated air is circulated and a coating solution is applied (liquid or powder). The coating material is dried on the pieces of material, and a plurality of thin layers are formed on each of the cores or small pieces of material. A series of rotating drums can be provided to provide the requisit e number or thickness of coating layers. In an alternate embodiment, initial coatings of material can be provided on the cores by a batch-type process before the materials are introduced into the continuous coating drums. The formulas for the coating solution can also be adjusted at different stages o f the coating process in order to provide a more consistent and uniform coatin g.
