Detectable Design


Detectable Desing pull ring u-shaped gasket
More safety for your goods


Foreign particles in a product are not acceptable in many industry sectors. Up to now, it was practically impossible to trace gaskets and seals, or parts of them, in the product flow. That changes with DETECTABLE DESIGN. JACOB has succeeded in incorporating minuscule metallic particles in the compound that the gaskets or seals are made of. Even the smallest parts of the seals can be found and removed from the production flow.

DETECTABLE DESIGN is the security guarantee for your production.

Jacob Signet Detectable Design
Added safety, not only for food applications

Maximum security for your goods

DETECTABLE DESIGN offers manufacturers in the food industry or sectors with sensitive goods even more security. All products of the DETECTABLE DESIGN line can be traced with the help of commercially available metal detectors and meet the requirements of EG 1935/2004 and the FDA. Should sealing rings or parts of them accidentally get into your production process, for example during routine maintenance, they can be identified and removed immediately by a metal detector. The smallest metallic particles make non-metallic elements such as gaskets, rubber covers and expansion joints detectable.

DETECTABLE DESIGN in operation – Our case studies

Case Study Buhler

The Bakery Innovation Center (BIC) of Bühler completely covers bakery processes – from conception to production. Tube and press­formed components by JACOB were used in the areas for bulk material handling and exhaust air aspiration. Because the systems in question are used for the processing of foodstuffs, components of the FOOD GRADE line were used exclusively. These fulfil the requirements of EC 1935/2004 as well as the FDA. Also included: the blue U­-shaped gaskets, which are metal detectable thanks to incorporated metal particles.

Case Study Sudzucker

For Sudzucker, JACOB has worked in collaboration with its distributor, mill, and silo construction specialist Kastenmüller, to develop a custom distribution system. The task: Distributing granulated sugar. All components must meet the specifications of EC 1935/2004 regulations, as well as American FDA food standards. In case of a seal failure, they must be detectable by metal detectors to ensure absolute product purity.
