Abstract

A process and apparatus for processing polyvinylacetate and other similar ingredients of a gum base or chewing gum product are disclosed. The ingredient materials are separated into individual pieces by a lump breaker and conveyed through a pneumatic conveying system to a cyclone receiver and holding bin. A volumetric feeder feeds the material into a side feeder which in turn introduces and feeds the material to the main continuous extruder used for making the final gum base or gum product. A unique adapter connects the side feeder to the main extruder which allows repair and/or modification of the side feeder without separating it from the main extruder.
