Tubular screw Easy Clean

Easyclean tubular screw conveyor - ECD

Easy clean Design Palamatic

Quick and efficient cleaning

The total removal of the screw flight from Easyclean screw conveyors allows rapid and efficient cleaning of the whole device. The reduced amount of residual material is due to the small gap (flight clearance) between the helicoil and the tube (less than 5 mm).
Easyclean screw conveyors are suitable for all conveying applications and/or extraction of powders or bulk materials where rapid and easy access to the inside part of the trough is essential for frequent cleaning. The screws are particularly used in the food, cosmetic, pharmaceutical or chemical industries.


Clean In Place (CIP): optimized design to meet special needs
For food or pharmaceutical processes, screws can be fitted with a water injection bar for cleaning by splash or spray.
