A new flexible screw conveyor for bulk foods, pharmaceuticals, dairy products and other contamination-sensitive materials meets 3-A sanitary standards. An innovative coupling design specific to the 3-A unit, that is positioned beyond the point at which material exits the discharge spout, virtually eliminates the potential of contamination, while allowing quick disconnection of the screw from the motor drive for washdown. The only moving part contacting material is a flexible inner screw that self-centers as it rotates, providing clearance between itself and the tube wall and creating a gentle, rolling action said to prevent separation of blended materials.
