Food Safety & Quality Control Instruments for F&B Production

Inline checkweighing is the first line of defence against short-weight claims and giveaway losses. A&D's current inline checkweigher, the AD-4961A series, weighs in motion with reject rates low enough to satisfy modern retailer specifications, and integrates with A&D's AD-4976 DETEX metal detectors via simple digital I/O, so a combination checkweigh-and-detect line needs no complex PLC programming. Both lines are supplied to order through A&D Gulf; the ProteX AD-4991 X-ray inspection systems are the third member of the family.

X-ray inspection identifies contaminants that metal detection cannot: glass, ceramic, dense plastic, stone, and bone fragments in packaged food. The A&D AD-4991 ProteX X-ray inspection system uses high-contrast imaging algorithms developed specifically for food applications, delivering reliable detection in products with variable density — raw meat, baked goods, and frozen foods where metal detectors frequently produce false rejects. Certification schemes such as FSSC 22000 certify your management system rather than the machine, so what an auditor looks for is the evidence around it: documented detection limits, certified test pieces run at a defined frequency, proof the reject diverted, and records that were reviewed. The AD-4991 is built to produce that evidence, and we supply the matching test pieces and calibration records.

Which precision balance for a food factory QC lab?

Recipe checks, pre-mix and flavouring dosing, yield calculations and lab QC all run on a precision balance rather than an analytical one: 0.01 g readability with a capacity that takes the container. For most UAE food QC benches that is the A&D GF-3002A or its internally calibrating twin the GX-3002A — 3,200 g × 0.01 g on a 165 mm square pan — with the FZ-5000i (5,200 g × 0.01 g) where batch containers are heavier. In wet or washdown areas the IP65 GX-M/GF-M and GX-K/GF-K lines carry the same readability in a sealed housing. A calibration certificate is available on request, and the GX models re-calibrate themselves when the room temperature drifts — the usual cause of a QC balance reading differently at 07:00 and at 14:00 in a Gulf plant.

Moisture content is a key quality and shelf-life parameter for snack foods, dried fruits, spices, and baked goods. The A&D MS-70 and MF-50 moisture analyzers provide rapid loss-on-drying measurement using uniform halogen heating, delivering results in 3–8 minutes compared to 24–hour oven drying methods. The 0.001% to 0.1% moisture resolution range covers the full spectrum from QC sampling in the lab to production-line release testing.
