More safety for your goods


The presence of foreign particles in a product is not acceptable in many industrial sectors. Previously, it was practically impossible to trace seals, or parts of seals, in the product flow. This is no longer a problem with DETECTABLE DESIGN. JACOB has succeeded in incorporating minuscule particles in the compound from which the seals are made. This means that even the smallest bits of seal can be detected and removed from the production flow.

DETECTABLE DESIGN guarantees the security of your production.

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 find their way into your production process, for example during routine maintenance, they can be identified by a metal detector and removed immediately. Tiny metallic particles make non-metallic elements such as seals, rubber covers and expansion joints detectable.

Jacob Pipework Systems in the Food Industry

For Südzucker, JACOB worked in collaboration with its distributor Kastenmüller, a specialist in mill and silo construction, to develop a custom distribution system. The task: Granulated sugar needed to be evenly distributed to the 12 outlets of a screening machine. All the components had to meet the specifications of EC 1935/2004, as well as American FDA food standards. The seals had to be detectable by metal detectors in order to ensure absolute product purity.

Jacob Pipework Systems in the Food Industry

Bühler’s Bakery Innovation Center (BIC) covers a complete range of bakery processes – from conception to production. Pipes and components from JACOB were used for bulk material handling and exhaust air aspiration. Because the systems in question are used for processing foodstuffs, all the components used are from the particularly high-quality FOOD GRADE line. These fulfil the requirements of EC 1935/2004 and the FDA. Also part of the system: the blue U­shaped seals, which are metal detectable thanks to incorporated metal particles.
