In modern food packaging operations-especially in high-speed vertical form-fill-seal (VFFS) lines-ensuring your product is free of metal contaminants is essential for both consumer safety and regulatory compliance. The Vertical Gravity Throat Metal Detector is specially engineered for free-falling dry products, offering compact, high-speed, and highly sensitive detection directly above your VFFS packaging machine.
Whether you're packaging powders, granules, grains, or snack foods, this metal detector protects your brand and production line by identifying and rejecting ferrous, non-ferrous, and stainless steel contaminants before the product is sealed in the bag.
A throat metal detector is a compact, gravity-fed inspection system installed between the weighing or dosing equipment and the bagging system-typically in vertical packaging lines. As the product falls through the detection coil, it is scanned for metallic contaminants. If a metal is detected, the product is diverted via a fast-acting reject system before reaching the packaging step.
This system is essential for bulk powders, fine granules, and dry food particles, commonly found in:
Form-Fill-Seal machines
Vertical packaging systems
Premade pouch fillers
Multi-head weighers and auger fillers
The Vertical Gravity Throat Metal Detector is widely used in:
Food Industry:
Rice, corn, sugar, flour, salt
Spices, seasonings, starches
Cereal flakes and granola
Tea and coffee powders
Snack pellets, dry beans, legumes
Nutraceuticals & Pharmaceuticals:
Protein powders, vitamins, dietary supplements
Chemical & Plastics:
Resins, pellets, granules, powdered chemicals
Agriculture:
Fertilizer, animal feed, seeds
Detects Fe, Non-Fe, and SUS304/SUS316L contaminants down to 0.3 mm, depending on aperture size and product flow.
Ideal for tight vertical packaging layouts, integrating directly above the VFFS bagger and beneath the weigher or filler.
When contamination is detected, the system activates an air-blast or flap-style diverter, removing contaminated material from the flow stream before packaging, reducing waste and protecting machinery.
Built with SUS304 or SUS316L stainless steel, the system offers IP65 or IP66 protection, suitable for food plants requiring hygienic standards.
Digital signal processing automatically adjusts for product effect and environmental noise. Perfect for fine powders, conductive products, and dry blends.
A 7" or 10" color touchscreen offers multi-language support, password protection, product memory storage (up to 100-200 profiles), and real-time monitoring.
Connects to USB, Ethernet, or RS485 for integration into SCADA or ERP systems, ensuring inspection traceability and compliance with food safety audits.

Product exits the multihead weigher or auger filler, free-falling into the throat metal detector.
The metal detector tunnel scans the product stream for metallic contamination.
If metal is detected, the system instantly activates a high-speed reject mechanism, ejecting the contaminated product from the flow path.
The clean product continues into the form-fill-seal bagging machine, ensuring only safe, contaminant-free bags are sealed and sent to market.
Catch contaminants before they enter the bag, preventing waste, false rejects, or damage to form-seal components.
Perfectly suited for powders, grains, and other free-falling solid materials common in food and pharmaceutical industries.
Easily mounted between packaging equipment, this compact unit minimizes footprint while maximizing inspection capabilities.
Complies with HACCP, IFS, BRC, GFSI, and FDA requirements, supporting safe food production and global exports.
Precision air-blast or flap gate systems target only contaminated portions, reducing product waste and improving yield.
Larger or smaller apertures for specific product flow sizes
Dual chute options for multi-head VFFS lines
Reject verification sensors for enhanced traceability
Custom reject bin with lock and tamper alarm
Explosion-proof versions for hazardous powder materials
Anti-static components for fine powder detection
Dust-tight enclosures for dusty environments
Built-in checkweigher integration or downstream X-ray
The Vertical Gravity Throat Metal Detector complies with:
CE Certification (EU standards)
ISO 9001 and ISO 22000 Quality Systems
FDA-compliant contact parts
HACCP and GFSI Food Safety Protocols
RoHS and IP66 ratings (optional)
