Abstract
A steam venting extruder feeder is provided for gravity feeding of flowable solid materials into a food extruder downstream of the first normal first zone feed port. The steam venting extruder feeder feeds the material down a tube while simultaneously venting steam from within the extruder around the periphery of the feed tube inside an outer tube in which compressed air is forced to assist in the flow of steam and pulls air in with the feed material preventing steam condensation and build-up in the feed tube.
