Snack Safety, Fast & Reliable

Fanchi-tech FA-MD Series Metal Detector Helps Royal Sandwich Co.—UK’s Top Lunchtime Snack Maker—Secure HACCP & ISO 9002 Compliance
For Royal Sandwich Co., a leading UK manufacturer of ready-to-eat sandwiches and the force behind the UK’s fastest-selling lunchtime snacks, “speed” and “safety” are non-negotiable. When the brand needed to fortify its 6 production lines with reliable metal detection—one that could handle 14 daily product changeovers, meet strict HACCP/ISO 9002 standards, and avoid costly downtime—it turned to Shanghai Fanchi-tech Machinery Co., Ltd. The solution? The FA-MD Series Metal Detector—a perfect fit that keeps 50+ sandwich varieties safe and production on track.

About Royal Sandwich Co.: A Leader in Lunchtime Quality

As a key supplier to the UK’s top supermarkets and convenience chains, Royal Sandwich Co. produces over 50 unique sandwich lines (from classic BLTs to gourmet vegan wraps) at its Tamworth, UK facility. Operating to ISO 9002 quality standards and rigorous HACCP protocols, the brand faces two critical pressures:

Ultra-Fast Turnaround: Order lead times often shrink to under 24 hours—so 6 production lines must run without unplanned stops.
Zero Metal Contamination Risk: With ingredients ranging from deli meats and cheeses to fresh veggies, even tiny metal fragments (from processing equipment) pose a threat to consumer safety and retail trust.

Having researched food-grade metal detectors, Royal Sandwich Co. chose Fanchi-tech for its reputation in reliable inspection solutions—and the FA-MD Series’ ability to solve their unique pain points.

The Challenge: Balancing Production Speed & Compliance

Royal Sandwich Co. faced three core hurdles that basic metal detectors couldn’t overcome:

Frequent, Fast Changeovers: With 50+ sandwich varieties and 14 daily product switches, the team needed a detector that could reconfigure in minutes (not hours) to avoid disrupting 24-hour order timelines.
Non-Negotiable HACCP Compliance: HACCP rules demanded hourly sensitivity checks, traceable logs of tests, and failsafes to prevent uninspected products from shipping. Basic detectors lacked secure, unalterable data logging.
Reliable After-Sales Support: A broken detector would halt production—catastrophic for a brand with tight delivery windows. The team needed a partner that could provide fast, on-site support.

Fanchi-tech’s Solution: FA-MD Series Metal Detector

After auditing Royal Sandwich Co.’s production workflow and compliance needs, Fanchi-tech deployed the FA-MD Series Metal Detector—engineered for high-volume, fast-paced food production. The system addressed every challenge head-on:

1. 3-Second Auto-Calibration for 100+ Products

The FA-MD features Smart Product Memory that stores calibration settings for up to 100 unique products. For Royal’s 14 daily changeovers, this means operators can switch between a 200g chicken sandwich and a 350g wrap in just 3 seconds—cutting total changeover time to under 5 minutes, perfectly aligning with their production pace.

2. HACCP-Ready Smart Validation System (SVS)

To meet strict HACCP requirements, the FA-MD includes an integrated Smart Validation System (SVS). It automatically alerts operators with a blue light when hourly sensitivity checks are due, logs test results (date, time, operator name) in an unalterable digital record, and locks production if tests aren’t completed. This ensures no metal-contaminated product leaves the facility—and provides retail auditors with clear compliance proof.

3. Ultra-Hygienic & Durable Design

Built for food industry demands, the FA-MD meets IP69K ingress protection standards—with smooth surfaces and no crevices to trap food particles. It withstands daily high-pressure washdowns, keeping Royal’s lines compliant with ISO 9002 hygiene rules.

4. 24-Hour European After-Sales Support

Fanchi-tech’s UK-based service team provides 24-hour response times. For Royal, this means if a detector needs maintenance, an engineer arrives quickly—avoiding the downtime that could derail their 24-hour order turnaround.

Client Testimonial: Royal Sandwich Co.

Jerry Morgan, Site Director at Royal Sandwich Co., praised the FA-MD Series and Fanchi-tech’s support:“Our goal is to wow customers with quality, hygiene, and on-time delivery—and the FA-MD Series makes that possible.
We used to struggle with slow changeovers, but now we switch 14 times a day in under 5 minutes—no more rushing to meet orders. The SVS system takes the stress out of HACCP checks; we never worry about missing a test or falsifying logs. And when we had a question last quarter, Fanchi-tech’s engineer was on-site in 4 hours—unbeatable support.
This detector isn’t just equipment—it’s the peace of mind we need to keep growing.”

Why FA-MD Series Stands Out for Snack & Sandwich Brands

For manufacturers like Royal Sandwich Co., the FA-MD Series delivers unmatched value:

Flexibility: Handles 100+ products to support diverse snack lines.
Compliance: Meets HACCP, ISO 9002, and BRC standards—critical for retail partnerships.
Reliability: Durable design and fast support minimize downtime.
