Magnetic Separation and Metal Detection for Food and Pharmaceutical Processing
Protect Product Integrity. Safeguard Patient Safety. Support Regulatory Requirements.
Bunting designs and manufactures magnetic separation and metal detection systems for food and pharmaceutical processing. With more than 60 years of experience, we help manufacturers remove metal contaminants, protect processing equipment, and support product safety and quality programs.
The Critical Cost of Metal Contamination
In Food Processing: A Threat to Consumer Trust and Safety
Metal fragments can enter the product flow through machinery wear, broken parts, raw ingredients, or packaging damage. Contaminants can create choking, internal injury, or dental risks.
Without appropriate detection and removal controls, contamination can lead to:
- Product recalls
- Potential liability
- Damage to brand reputation
- Supply chain disruption
In Pharmaceutical Manufacturing: Contamination Can Affect Product Quality and Patient Safety
Pharmaceutical equipment must be cleaned and maintained to prevent contamination and protect a drug's safety, identity, strength, quality, and purity.
Metal contamination in tablets, powders, or capsules can contribute to:
- Regulatory investigations
- Product rejection or recalls
- Patient safety risks
- Production delays or shutdowns
Each facility should select and validate contamination controls based on its process, product, and risk assessment.
Industries Served
We offer solutions for a wide range of food processing industries, including:
Bunting equipment is trusted across every segment of the food industry to prevent metal contamination during bulk handling, mixing, processing, and packaging. We support:
- Dairy Processing: Milk powders, cheeses, yogurts, and frozen dairy products
- Meat & Poultry: Ground meat, sausage, cooked products, and ready-to-eat meals
- Grains & Cereals: Flour, rice, corn, oats, wheat, and processed grain mixes
- Snack Foods: Chips, crackers, granola, nuts, seeds, trail mixes, popcorn
- Sauces & Condiments: Tomato-based products, dressings, dips, and purees
- Beverage Production: Juices, flavored waters, syrups, alcohol, and concentrates
Metal contamination can affect product purity and lead to failed batch testing in nutraceutical manufacturing. Bunting helps protect:
- Protein & Meal Replacements: Whey, soy, pea, collagen, and powdered blends
- Dietary Supplements: Capsules, tablets, powders, and gummies
- Herbal & Vitamin Products: Botanicals, multivitamins, immune blends
Pharmaceutical facilities require zero-tolerance metal control. Bunting systems are engineered for cGMP environments and support:
- Tablet and Capsule Production: Metal detection before and after tableting
- Powder Handling: Bulk APIs, excipients, and fine powders
- Liquid Pharmaceutical Processing: Injectable drugs, oral solutions, sterile suspensions
- Packaging Lines: Bottle, blister pack, and sachet inspection and quality control
Animal feed must meet safety standards to prevent harm to livestock and pets. Bunting helps manufacturers comply with FSMA and AFIA standards:
- Dry Kibble and Treats: For dogs, cats, and small animals
- Wet and Canned Foods: Including gravies, pâtés, and stews
- Feed and Meal for Livestock: Poultry, swine, cattle, equine, and aquaculture feeds
- Supplement Blends: Mineral mixes, vitamins, and performance nutrition

Metal Detection
Capture and retain ferrous contaminants from gravity-fed powders and pellets to protect equipment and ensure product purity.
Continuously separates and discharges ferrous metals for automated, high-volume processing.
Captures ferrous contaminants in pneumatic and gravity-fed systems without slowing flow.
Removes tramp ferrous metals from conveyed bulk materials using overhead magnetic separation.
Removes ferrous particles from liquids and slurries, ensuring purity and preventing contamination.
Removes tramp ferrous metals from gravity-fed product flow without disrupting throughput.
Remove ferrous contaminants from dry, free-flowing materials using stationary magnetic elements that fit easily into chutes, hoppers, and gravity flow systems.
Used where products fall freely by gravity through a detection coil, these detectors are ideal for inspecting granules, powders, and pellets.
Detects and removes metal contaminants from liquid, slurries, pastes and meat in pumped product streams. Custom-designed to fit any pipeline application.
Remove metal contaminants from powders, granules, and pellets in vacuum or pressure pneumatic lines. Ideal for plastics, chemical, and food processing.
Provide high-sensitivity inspection for food, plastics, recycling, and manufacturing. Available in one-piece and two-piece designs for easy integration.
Integrated conveyor and metal detection systems for the food industry. Detect ferrous, non-ferrous, and stainless steel contaminants to protect products, equipment, and brand integrity.
Frequently Asked Questions
Magnetic separators remove ferrous and weakly magnetic contaminants. Metal detectors can identify ferrous metals, non-ferrous metals such as aluminum, brass, and copper, and many stainless steels. Detection performance depends on the product, package, contaminant size, orientation, and system configuration.
Bunting systems detect and/or remove ferrous metals (iron and steel), non-ferrous metals (aluminum, brass, copper), and stainless steel—even when embedded inside product or concealed in packaging. Our high-intensity magnets and advanced metal detectors identify small particles.
Sanitary design options can support facility requirements related to USDA/AMS equipment criteria, FDA preventive controls, 3-A standards, GFSI-benchmarked certification programs, and HACCP plans. Applicable requirements depend on the product, process, installation, and equipment configuration. Confirm any required certification or acceptance with Bunting before specifying equipment.
Our sanitary-grade magnetic separation and metal detection systems are built to meet or exceed:
- USDA/AMS Meat and Poultry Accepted Equipment criteria
- FDA and FSMA regulations
- 3-A Sanitary Standards
- GFSI and HACCP compliance
We also manufacture food-safe and utility-grade equipment for non-contact bulk applications.
The right approach depends on the facility's hazard analysis, product, process, and packaging. Magnetic separators remove ferrous and weakly magnetic contaminants, often earlier in the process. Metal detectors can identify additional ferrous, non-ferrous, and stainless steel contaminants downstream. Using both can provide layered control when the application requires it.
Yes. Bunting offers compact metal detectors for tablets and capsules, plus magnetic separation equipment for bulk powders, excipients, and active pharmaceutical ingredients (APIs). Sanitary construction and cleaning features can be specified for the application. The facility remains responsible for qualifying and validating equipment under its quality system.
Yes. We offer equipment specifically designed for pharmaceutical cleanroom environments, including:
- Compact, sanitary metal detectors for tablets and capsules
- Magnetic separation for bulk powders, excipients, and APIs
- Designs that meet cGMP and CFR Title 21 §211.67 equipment maintenance standards
Yes. Available sanitary design features include 316 stainless steel construction, electropolished finishes, tool-free access for cleaning and removal, and food-contact gaskets and seals selected for the application. Confirm the required construction, finish, and certification before ordering.
Common sources include machinery wear, damaged screens, blades, mixers, or conveyor parts, dropped tools and fasteners, packaging components such as foil, staples, or twist ties, and contamination in incoming raw materials. Magnetic separators and metal detectors can help remove or identify contaminants at selected control points.
Yes. Bunting's applications lab can evaluate supplied material under representative separation or detection conditions and use the results to recommend equipment and settings. Contact Bunting to confirm sample requirements, availability, and testing terms.
Consider the product, likely contaminant types and sizes, flow rate, line configuration, cleaning or washdown requirements, package material, available installation space, and validation needs. Sample testing and an application review can help determine the appropriate magnetic separator, metal detector, or layered system.
