Abstract: A zero contact double screw and ergonomic double screw housing combination for foodstuff mixers and portioning devices. The system includes a multi-prong support segment at the discharge end of the double screw and double screw housing which connects and secures the double screw to the double screw housing to support and space the double screw apart from the surrounding double screw housing in a configuration which eliminates contact between the outer surface of the double screw and the inner surface of the double screw housing. The housing has an exterior portion with scooped out portions providing for substantially reduced thickness, volume, and mass, while remaining configured to provide durability and longevity of use similar to that of a screw housing that is substantially fully cylindrical throughout its diameter.
