Metarom, a producer of flavours, colours and caramels for drinking, dairy and ice-cream products, uses weighing equipment from Mettler Toledo at its production site in northern France.

At the site, the ISO 9001:2000-certified company manufactures its entire range of flavours, colours and caramels in powders and glazes as well as water-soluble and fat-soluble liquids.

Several specialised workshops have been set up, each focusing on a different aspect of production, from development to packaging.

Metarom’s in-house research and development team uses a technical laboratory to formulate and test new custom flavours.

Raw ingredients are created in the ‘bases’ workshop using Mettler Toledo IND690 weighing terminals connected to XS scales.

Mettler Toledo specialists suggested that customised marble worktops would provide a more stable weighing surface, which would, in turn, help Metarom food chemists to ensure maximum precision by preventing vibration-related volume errors.

In its storage area, the company uses 14 large-volume tanks fitted with weighing sensors, which are said to provide more efficient stock management than level controllers.

Advanced calibration services from Mettler Toledo have helped to streamline storage tank quality control.

Mettler Toledo specialists have also weighed in on the accuracy of Metarom’s floor-mounted, three-ton-scale systems used to weigh hoppers and blenders, as well as the truck scales that measure items on the move.

Finally, in production areas such as Metarom’s caramel workshop, copper pots mimic traditional cooking methods while natural extracts are processed in a high-technology, low-emissions distillation unit.

Various balances reviewed by Mettler Toledo ensure that recipes meet exacting, time-tested standards.

Mr Manguet, the Mettler Toledo service manager for northeastern France, conducted an onsite diagnosis of Metarom’s weighing equipment.

He drew up a testing schedule to cover all of the company’s diverse weighing assets and meet its drive for consistent quality.

‘One way we helped to streamline quality control efforts was to optimise how under-tank sensors are calibrated,’ said Manguet.

Tank capacities vary from 150kg to 10 tons.

Using a volume counter linked directly to French accreditation agency Cofrac, it took two days to effectively calibrate Metarom’s 14 tanks.

Collaboration between the two companies is continuing, with studies using a new weight-based formulation traceability software tool at the Boves site now under way.

The latest IND690 weighing terminals delivered to Metarom, equipped with Ethernet interfaces, are ready to communicate with the enhanced software package.

Metarom and Mettler Toledo are also considering weighing sensors for alcohol storage tanks used in distillation.
