A new flexible screw conveyor for bulk foods, pharmaceuticals, dairy products and other contamination-sensitive materials meets 3-A sanitary standards, according to David Boger, sales manager, Flexicon Corporation.

An innovative coupling design specific to the 3-A unit 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 drive motor for wash down.

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 the separation of

blended materials. Numerous standard and custom-engineered screws are offered to move bulk materials ranging from large pellets to sub-micron powders, including products that pack, cake, smear, break-apart, seize or fluidize, with no separation of blended products.

Mobile units are also available, as well as high-capacity models.
