FA-MD Series Metal Detector – Reliable Foreign Body Control for All Kinds of Packaged Food

For food manufacturers around the world, metal contamination is one of the biggest threats to product safety, brand reputation and retail compliance. Even tiny metal fragments can lead to product recalls, market penalties and permanent damage to consumer trust. To solve this problem, Shanghai Fanchi-tech Machinery Co., Ltd. provides the FA‑MD series metal detector with stable performance, high detection sensitivity and food‑grade standard design, which has been widely used in bakery, snack, frozen food, prepared food and other packaged food production lines.

This case shares the practical application of FA‑MD metal detector in BakeBest Food Ltd., a medium‑sized baked food manufacturer in the EU, to show its real performance and value in actual production.

The Customer’s Pain Points Before Using FA‑MD

BakeBest Food Ltd. mainly produces all kinds of packaged bread, cakes, cookies and pastries, with a daily output of more than 60,000 packs. Before cooperating with Fanchi‑tech, the company used an old‑style metal detector, which had been unable to meet its production and safety needs:

High false reject rate

The high sugar, oil and protein ingredients in baked goods caused serious interference to the old equipment, resulting in frequent false alarms. About 8% of qualified products were wrongly rejected every day, causing serious waste of raw materials and increasing production costs.
Insufficient detection sensitivity

The old machine could not stably detect small metal fragments below 1.2 mm, while metal residues from mixing, cutting and packaging equipment were usually between 0.6 mm and 1.0 mm, which brought great hidden dangers to food safety.
Difficult to clean and poor hygiene level

The frame and conveyor belt of the old equipment were not designed for food hygiene standards. It was easy to accumulate cake crumbs and oil dirt, which could not adapt to daily cleaning and disinfection, and was repeatedly warned during BRC and food safety audits.
Complicated operation and low efficiency

When switching between different products, it needed long‑time manual adjustment and calibration, which seriously affected the production line speed and order delivery efficiency.

After a small metal fragment was found in a batch of products in 2025, the company decided to completely replace the metal detection equipment and finally chose Fanchi‑tech FA‑MD series metal detector after many comparisons and on‑site tests.

FA‑MD Metal Detector: Customized Solution for Packaged Food

Fanchi‑tech FA‑MD series metal detector is a professional metal detection equipment designed for medium and small packaged food. It adopts standard food‑grade flat conveyor belt, full 304 stainless steel body, compact structure, easy to install and integrate into various automatic packaging lines. The equipment is not plate chain type, but adopts smooth, stable and easy‑to‑clean conveyor belt, which is especially suitable for bakery, snacks, frozen food and other conventional packaged products.

1. High Sensitivity & Low False Rejection Rate

FA‑MD adopts dual‑frequency digital detection technology and intelligent anti‑interference algorithm, which can effectively suppress the product effect interference of high sugar, high oil and high moisture food.

Ferrous metal: ≥ 0.6 mm
