UNITARY SCREW CONVEYOR APPARATUS ABSTRACT Screw conveyor apparatus fabricated from integrally molded plastic modules is disclosed. The apparatus includes a multiplicity of modules axially aligned and joined or bonded so as to provide a unitary plastic screw conveyor of a desired length. A plastic axial member extending the length of the screw conveyor and which defines Ann elongated aperture of a non-circular cross-section is formed by joining or bonding the individual modules. In addition, each of the modules include a flight member which individually helically encircle not more than 360°, but when bonded together result in an overall flight member encircling more than 360° and which extends the length of the joined or bonded modules. The plastic screw conveyor is driven by a drive shaft which has a non-circular cross-section and which is inserted through and cooperates with the non-circular aperture extending the length of the joined axial members. A drive or power source is connected to the drive shaft for rotating the apparatus.
