CONTINUOUS DRUM-COATING OF GUM PRODUCTS

摘要

A continuous coating process for chewing gum and bubble gum materials. Small cores or pieces of gum material 20 are introduced into inclined rotating dru ms 34, 34' in which heated air 52 is circulated and a coating agent 50 is appli ed (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 piec es of material. A series of rotating drums can be provided to provide the requisite 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 drum s. The formulas for the coating solution can also be adjusted at different stag es of the coating process in order to provide a more consistent and uniform coating.
