Why Choose MQ-MD-C
Honest, tiered sensitivity ratings
Sensitivity is tied directly to aperture height, so we rate it honestly across eight tiers: at a 100mm aperture, ferrous from Φ0.6mm and non-ferrous from Φ1.2mm; at 400mm, ferrous from Φ3.0mm. Match your product height against the chart and the real detection capability is clear at a glance — no games with "lab-condition" numbers.
Stainless steel contaminants can't escape
Chipped blades and broken sieve wires are usually 304 stainless — weakly magnetic with a faint signal, the toughest catch in metal detection. This machine detects SUS304 spheres from Φ1.2mm at the 100mm aperture, with full coverage of ferrous, copper, aluminum and stainless steel — no blind spots for contamination.
False-reject rate below 0.1%
False alarms wear a line down faster than misses — every alarm stops the belt, so operators keep dialing sensitivity down until the machine is just decoration. We hold false rejects under 0.1%, and one-touch auto-learning suppresses product effect, so salty or moist products run stably at full sensitivity with no compromise.
Stop on detection, every pack accounted for
When metal is detected, the conveyor stops automatically with a buzzer alarm and the suspect pack stays right at the detection point — nothing contaminated flows downstream. Lines that must run non-stop can add an optional reject mechanism that automatically kicks out suspect packs without breaking the production takt.
One-touch learning for fast changeovers
No factory technician needed for a new product: run a few packs through, the machine learns the product effect automatically and stores it in the parameter library — next time, recall the saved parameters and start the line. Touch-key input (touchscreen upgradable) with multi-language UI; an ordinary operator works independently within a day.
Mirror-finish 304 body that passes audits
Full SUS304 mirror-finish stainless body with crevice-free clamp construction — washdown and wipe-down leave no trapped residue, meeting HACCP, GMP and CAS system requirements. When customers audit your floor, the machine itself earns you hygiene-management points.
Problems It Solves for You
Export audits require metal contamination to be set as a CCP critical control point, but manual visual checks and magnet bars produce no detection records — you get written up with non-conformities right at the audit
In-line all-metal detection from Φ0.6mm ferrous (100mm aperture), full 304 stainless construction compliant with HACCP, GMP and CAS — a concrete hardware anchor for your metal-contaminant CCP, with audit-ready, traceable evidence.
A cutter blade chips or a sieve wire snaps on the floor, stainless fragments end up inside vacuum packs, the customer opens a bag and complains — one penalty wipes out a month's profit
Sensitivity is specifically calibrated for weakly magnetic 304 stainless: Φ1.2mm stainless spheres are detected at the 100mm aperture, so blade chips and broken wires — the most frequent contaminants — are intercepted before shipment.
The old detector cried wolf on every salty or moist product; operators got fed up and kept lowering sensitivity until the machine existed in name only — you only found out after an incident
False-reject rate <0.1%, with one-touch auto-learning that memorizes each product's material effect — sensitivity never has to be sacrificed to keep the line quiet, and the machine genuinely stays on duty year-round.
One line runs a dozen-plus SKUs; every changeover means re-tuning and half an hour waiting for the machine to stabilize — capacity burned on switching
Product parameter memory: learn each SKU once and it is archived permanently. At changeover, recall the parameters and run immediately — seamless switching for multi-product lines.

Functions in Detail
Alarm and rejection options
Standard configuration is stop-on-detection: when metal is found, the conveyor halts with a buzzer alarm and the operator removes the suspect pack for review — ideal for low- to medium-speed lines and strict sample-retention traceability. High-volume lines that cannot stop can add an optional reject mechanism that automatically ejects suspect packs while the main line keeps running.
Aperture selection and customization
The standard aperture is 400mm wide with eight height options: 100/120/150/200/250/300/350/400mm; 500mm and custom sizes are available for extra-wide products. The selection rule: keep the aperture as close to the product as possible — the lower the aperture, the higher the sensitivity, down to Φ0.6mm ferrous at the 100mm tier. Send your product dimensions and we will recommend the right configuration.
Operation and parameter management
Touch-key input, upgradable to a touchscreen, with a multi-language interface. New products go through one-touch auto-learning: run a few real packs, the machine records the product effect and saves it as that SKU's parameter set. Later changeovers simply recall the stored parameters and start the line — no repeated tuning, no capacity lost to switching.
Cleaning and hygienic design
Full SUS304 mirror-finish stainless body with crevice-free clamp construction — gaps trap no residue, washdown leaves no standing water, and daily cleaning is a simple wipe or rinse. Materials and structure meet HACCP, GMP and CAS food-safety requirements; waterproof, dustproof, anti-vibration and explosion-proof configurations are available for wet, cold or dusty rooms.
Power supply and line integration
Standard power is AC200V±10%, 50-60Hz; AC110V, AC380V and other voltage standards can be specified for export equipment or special plants. The machine slots into your existing conveyor line as an independent section, with the conveyor and reject systems adapted flexibly to your line height and takt — retrofitting an old line requires no major rebuild.
Industries & Application Scenarios
Candy and puffed snacks pass through in full cartons or single packs after packaging; a 100-150mm low-aperture configuration exploits the Φ0.6-1.0mm ferrous sensitivity to intercept metal wear debris shed along the production line.
Bottled and canned supplements pass through upright; choose a 120-200mm aperture tier to match bottle height, detecting ferrous from Φ0.8-1.2mm to keep tooling debris from tableting and filling out of pharma-grade product.
Flat vacuum packs of meat and braised products can run through a 100mm aperture to use the highest sensitivity tier; an optional waterproof body suits cold, wet washdown rooms.
Bread and pastries are inspected after packaging, intercepting iron and stainless debris from worn blades and mixing paddles in kneading and cutting; one-touch auto-learning handles frequent multi-flavor changeovers.
Bagged powders and dried or roasted goods show strong product effect; auto-learning suppresses the product signal, maintaining detection of non-ferrous metals like copper and aluminum from Φ1.2mm while holding false rejects under 0.1%.

Indonesia's 17 October 2026 Halal Deadline: What It Actually Means for Your Inspection and Weighing Equipment
On 17 October 2026, Indonesia's mandatory halal certification obligation reaches imported food and beverages, and also reaches Indonesian micro and small food and beverage enterprises. The date comes from Government Regulation PP 42/2024, which set a grace period ending no later than 17 October 2026. This article answers the question exporters keep asking equipment suppliers: does a checkweigher, metal detector, or X-ray inspection machine need to be halal certified? The short answer is that certification attaches to products, not to machines — but the machines still show up in the file, because the certification body has to be satisfied that nothing on your line contaminates the product. We walk through the two-phase structure behind the date, the meat and dairy carve-out that trips up importers, how foreign halal certificates are recognised through mutual recognition agreements with BPJPH, and what exemptions exist. Then we give you a checklist you can hand to your engineering team, written by people who build the equipment rather than sell the certificate.
How to Validate a Vendor's AI Inspection Claims: The Questions Nobody Wants You to Ask
Almost every accuracy number attached to "AI-powered" food X-ray inspection today is a vendor claim with no independent verification behind it. When you trace the most widely circulated figures back to their source, you land on equipment-maker and SaaS marketing blogs — not peer-reviewed studies, not third-party test reports. Searches aimed specifically at peer-reviewed validation of these numbers return vendor technical documents instead. And no vendor we found discloses the three things that would make an accuracy number meaningful: the test method, the sample size, and the confidence interval. This article is not an argument that AI inspection doesn't work. It is a practical guide to telling a real capability apart from a marketing sentence. It explains what the peer-reviewed literature actually says the hard problem is (training-data annotation, not model architecture), why a demo on a vendor's samples proves almost nothing about your line, and gives you a printable list of questions to put in front of any supplier — including MIQI. Written by Engineer Cai for engineers and QA managers who have to sign off on the purchase.
What X-Ray Inspection CANNOT Detect: An Honest Limitations Guide
Almost every X-ray inspection page online tells you what the machine finds — metal, glass, stone, bone, dense plastic. Very few tell you what it misses. X-ray imaging works on density contrast: the beam is absorbed differently by different materials, and the detector renders that difference as grey. When a contaminant absorbs roughly as much radiation as the food around it, there is no contrast, and no contrast means no image — regardless of software, AI, or price tag. This guide walks through the physics behind that limit, the contaminant families it affects (hair, paper, low-density plastics, cartilage, string, wood), the product-side conditions that make a detectable object undetectable, and a practical checklist for deciding when X-ray is the right tool, when a metal detector is the better answer, and when you need both. Written by an engineer at a factory that builds all three — which is exactly why we can afford to tell you when X-ray will not save you.
