Archimede screw


Handling system with modular Archimedes screw

ArchimedysTM was born to meet the need of the worldwide leader of towed harvesting machines ALMA. Actually, he had a problem of manufacturing with Archimedes screw used to move and select grapes.

The goal was to find a modular solution, reliable and economical, with polymer materials, to adapt various screws on the sorters.

Alma-ARNAUD called on Exventys, specialist of industrial innovation, to develop a new concept of screw, without any risk of deterioration for the fruit and more reliable in use.

Innovation award 2011From the idea to the implementation

After studdying international patents, Exventys didn’t find any suitable solution :  there wasn’t any efficient modular Archimedes screw that could be exploitable industrially in severe use conditions.

This was due to the extreme difficulty in obtaining a piece with high mechanical resistant polymers and a form that guarantees the transmission of a significant effort without any performance loss.

Exventys organized its innovation approach and proposed a solution to its customer, including formalized and non formalized clauses of the technical specifications.

Exventys, thanks to the TRIZ method and 3D printing, proposed, tested and industrialized in record time, a solution that could solve all technical contradictions due to the use of a polymer screw to move powdered products.

The screw price is 10 times cheaper than the original solution and the level of performance is higher than all the projections.

From the prototype to the development of a whole range

Iserco company, a worldwide player specialized in vibrating bottoms production and powdery products transportation, detected very quickly the potential of ArchimedysTM system in industry and contributed to define a range of standard modules to build Archimedes screw in kit form, without any welding or finalization operations.
