Where to Install Magnetic Separators in Pet Food Processing
The complexity of processing, from ingredient handling to packaging, introduces multiple stages where foreign metal fragments can enter the production line. Although many processors understand the importance of magnetic separators in enhancing food safety, uncertainty often arises about the most effective equipment placement for optimal product security and machinery protection.
Effective Placement of Magnetic Separators
Strategically placed magnetic separators is critical for ensuring pet food safety and quality. There are a few locations where installing magnets is most beneficial:
1. Product intakes: Magnetic separators at the product intake stage —for both dry and wet ingredients applications— are essential for removing metal fragments, such as magnetic stones and work-hardened stainless steel, safeguarding machinery, and ensuring incoming materials meet quality standards. This is an important magnet to ensure that the product coming into your process meets your requirements.
2. Post-first stage mixing/wet ingredients processing: After the initial mixing phase, magnetic separators help extract contaminants introduced during processing. This stage reduces the strain on final-stage magnets, especially in cases with high contamination levels.
3. Wet line before canning/packing: In wet pet food production, magnetic separators play a vital role in the canning stage. Proper consideration of flow rate, particle size, and viscosity ensures effective contaminant removal, protecting expensive equipment like twin-screw pumps while safeguarding the final product before packing and metal detection.
4. Dry ingredients processing: Magnet placement during dry ingredient processing depends on factors like flow rate and protection level. Installing separators before extrusion prevents contaminants from being embedded in kibble, streamlining quality control measures and reducing potential hits on final-stage magnets.
5. Dry line before bagging: The final magnet before bagging serves as the last defense against contaminants before products reach consumers. Certified and traceable magnets provide reliable quality assurance and help demonstrate effective preventive measures.
Choosing a magnetic separator for these applications will depend on the flow rate, density, speed, and more.

Improving Product Purity in Meat Rendering and Pet Food Processing
Sources of Metal Contamination in Meat Rendering
In the meat rendering industry, the sources of metal contamination vary depending on the part of the process and type of product. The objective of a magnetic separator is to prevent an unacceptable amount of contamination generated in a milling process being transferred to the client to deal with.
For example, many ovine meal processors face a challenge with removing slow-release capsule springs from rendered meat, which get ground-up within the product. Having a magnetic separator to extract these fine metals is an excellent way to increase the quality controls and solve this issue.
A common source of contamination found in poultry processing are magnetic stones, which originate from the gut of the poultry and are ingested from the ground while feeding. The magnetic stones can be removed by utilising powerful magnetic separation equipment.
Another very common source of metal contamination in meat rendering is the hammer mill. As the hammer mill materials slowly wear away, these metal fragments (coarse and fines) are introduced into the product. Effectively extracting these fragments can only be done with a strategically positioned, high-intensity magnetic separator.
To reduce machine protection issues in the meat rendering industry, these types of magnetic contamination need to be removed from the process. Factors such as screen breakage, downtime, loss of production, and tramp iron contamination causing fires/explosions in the hammer mill can all be drastically reduced by placing correct metal fragment controls in place. This means less downgraded products, reduced quarantined shipments, prevention of brand name damage, and satisfied clients!
Many rendering industry professionals state that they were not aware of the levels of fine metal fragments within their meat and bone meal until installing a magnetic separator and seeing the vast amount of magnetic fines extracted. A great way to discover the levels of metal contamination in your finished meat meal is through utilising a certified Lab Test Magnet Probe. The magnetic probe is placed into the bag of finished meal and swirled around to collect magnetic fragments and provide an indication of the metal contamination levels.
Sources of Metal Contamination in Pet Food Processing
Predominantly, metal contamination comes from bulk ingredients and is then distributed throughout the product lines. The remainder of contamination is generated in the process and varies greatly depending on the type of impact machinery that is used for sizing and screening ingredients and the longevity and wear of conveying systems.
The objective of magnets in pet food is to control contamination on bulk intakes and to also act as a final control prior to packing areas and metal detection. Magnetic separators play a crucial role in retaining the magnetic fines contaminants that are below sensitivity threshold of metal detection before they reach the CCP. An efficient magnet will drastically reduce waste from metal detectors and improve product purity from magnetic fines contamination.
Magnetic Separation Solutions for Meat Rendering & Pet Food Processing:
Mag-Ram® Automatic Self-Cleaning Magnet
The Mag-Ram® Automatic Self-Cleaning Magnet has proven to be one of the best performing and successful magnets as it can be programmed to automatically clean itself and therefore save operator time, as well as reduce safety risks. Typically installed at incoming dry materials locations (such as MBM or grain) and final dry product/bulk out-loading locations.
Mag-Ram® Self-Cleaning Magnet in meat rendering
In some applications, the contamination is so high that manually cleaning conventional grate magnets is neither practical nor convenient. Once contamination builds up over the magnetic bars, the magnet's strength is 'cancelled out', meaning that further contaminants passing over the magnet just keep flowing down the product stream and remain in the finished product.
The modular design of the Mag-Ram® allows it to handle anywhere between 3T to 90T per hour! This self-cleaning magnet can clean one ram at a time or all at once, and a wear equalization feature is incorporated to prevent flat spots on the magnet and uneven wear on the seals. This means more reliability for a longer period of time.
The Mag-Ram® magnetic bars/rams are engineered to rotate with each cleaning cycle, and short bursts of air are directed at the magnets also help remove the pyramid of excess material from being carried over to the reject side. This means a lean contaminant sample is achieved, easy to analyse for more accurate traceability of risks and less product wastage.
Spherical Inline Pneumatic Transfer Magnet
Where a gravity-feed magnet, such as the Mag-Ram®, is not feasible and the product is pneumatically conveyed via blow, vacuum, or pneumatic transfer line, a Spherical Inline Pneumatic Transfer Magnet is a very effective solution. These aerodynamic magnetic separators are very resilient in high-flow and abrasive applications and enable efficient extraction and retention of metal from high-velocity powder lines without experiencing bulk density problems.
Spherical Inline Pneumatic Transfer Magnet
Dual Round Nose Plate Magnet
For difficult-to-flow applications with products such as cakes (or crax), or applications processing chicken frames, whole muscle products, poultry, beef, lamb, venison, etc, a Dual Round Nose Plate Magnet is an efficient solution. For pet food processing applications, these units can be installed prior to expensive processing machineries, such as grinders, shredders, dicers, and emulsifiers, to remove metal fragments to avoid costly damage, downtime for repair/maintenance, and loss of production. Dual Round Nose Plate Magnets easily pick up chunky contaminants such as nails and bolts from the product and protect machinery without an unacceptable restriction to the product flow.

Improving product purity in pet food with magnetic separators
More 'humanised' pet foods have become available on the market and are becoming increasingly popular among pet owners, who want the very best, healthy meal options for their beloved pets.
We have seen a change in quality control in the pet food and meat rendering industries, with a heightened focus on product purity, including metal fragment control.
These industries tend to have high levels of metal contamination in their product, as the meat and bone meal product can be very abrasive to process and tends to wear down machinery more quickly than some other product types. The contamination can originate from various stages of processing, as well as from the product itself, so it is important to install metal fragment controls such as magnetic separators or metal detectors in various locations, and in particular, the most final stage in a processing line prior to packing.
How to know where to install magnetic separators?
Choosing a location for food magnets will depend on multiple factors. For example, the amount of metal contamination within the product can play a significant role, as this can affect any existing magnets in the processing line and their ability to collect and retain the contaminants. With a high level of metal contamination, a magnet that requires manual cleaning can get overloaded and 'short out', meaning that it cannot collect and retain more contamination. Any additional metal contamination can then flow past the overloaded magnet and remain in the product.
This highlights the importance of having upstream magnetic separators to offload the final magnets in food processing lines, especially ones that have a high level of metal contamination. The importance of cleaning magnets frequently also shouldn't be overlooked and should be a crucial step in manufacturing procedures.
Another example of a reason to install magnetic separators can be to protect machinery from damage caused by certain non-ferrous or ferrous metal contamination. Depending on the product and processing line, as well as the type of contamination, there are a number of magnetic separation solutions suited for the job.
The Magnattack® Magnetic Separation range for pet food has proven to be very effective in both dry and wet product applications. Let's have a look at each magnetic separation solution and the type of product each magnet is designed for:
Magnetic Separation Examples for Dry Pet Food Products
Magnattack® manufactures a number of magnetic separators for dry pet food processing applications.
Mag-Ram® Self-Cleaning Magnet
The Mag-Ram® Self-Cleaning Magnet has proven to be an amazing self-cleaning permanent magnet and metal fragment control solution for dry products and incoming raw materials such as MBM, protein meal, grain, final kibble, and more.
With the ability to configure the cleaning cycle to suit tonnage rates and contamination levels, the Mag-Ram® gives operators the ability to have the magnet frequently cleaned, and automatically.
This self-cleaning magnet requires zero downtime, with no need to stop production, which is a huge benefit for processors with products high in metal contamination that cannot stop production for frequent cleaning. The rotating magnetic rams ensure minimal product build-up and blockage, and the magnet design provides excellent product stream coverage.
Not only this, but the magnetic rams can be configured to be cleaned one at a time, meaning that your product stream remains covered by the other magnetic rams! You are truly going to want to add this self-cleaning magnetic separator to your materials handling equipment wish list!
Rapidclean® Grate Magnet in Housing
The Rapidclean® Grate Magnet overcomes issues associated with conventional magnetic grates, such as stainless steel sleeves, cleaning difficulties, jamming, safety issues, and more. This permanent magnet consists of open-ended magnetic bars, and once the magnetic drawer is opened, the cleaning is completed away from the product stream, using the Rapidclean® Cleaning Tool.
This grate magnet is designed for dry products, such as meals, powders, grain, and premixes.
Dual Round Nose Plate Magnet System
The Dual Round Nose Plate Magnet System is another industrial magnet design suited for pet food applications. This magnetic separator can be installed in applications processing chicken frames, whole muscle products, poultry, beef, lamb, venison, final meal products and more, prior to expensive processing machinery such as grinders, shredders, dicers, and emulsifiers.
In some applications, especially those with high tonnage and fast-flowing products, fragments can be brushed off plate magnets by the oncoming product and back into the product stream. To reduce this risk, Magnattack® has developed the RE80® Round Nose Plate Magnet. This system features a High-Intensity RE80® Bar Magnet at the end of a standard magnetic plate. The Separation Bar Magnet offers protection against dislodged fragments and prevents them from re-contaminating the food product. When metal fragments are collected by the Separation Bar, they are washed safely to the underside of the magnet and out of the path of oncoming product.
With the deep field capability of the magnetic plate added to the intensive coercive force of the Separation Bar, you gain far superior control over foreign metal pieces and increased protection against contamination.
Spherical Pneumatic Transfer Magnet
The Spherical Pneumatic Transfer Magnet is a powerful magnet designed for high-velocity blow, vacuum, gravity, and pneumatic transfer lines. This magnetic separator suits pneumatically conveyed powders, grains, premixes, and palatant products. The aerodynamic design of this Magnattack® system enables efficient extraction and retention of metal from high-velocity powder lines, without experiencing bulk density problems.
The Spherical Magnet is considered a more hygienic, powerful and superior alternative to traditional bullet-style and cartridge-style magnets.
Magnetic Separator for Wet Pet Food Products
Emulsion & Slurry Pipeline Separator
The Emulsion & Slurry Pipeline Separator is an inline liquid magnet that is ideal for viscous liquid applications including meat emulsions, meat slurries, and more.
It is often difficult to extract weakly magnetic fragments from viscous meat emulsions, slurries, and liquids. In answer to this problem, Magnattack® has developed a special hydro-dynamic magnet system specifically for this purpose. The units are an efficient and sanitary alternative to Liquid Trap/Finger Pot Magnets, which can also be heavy and difficult to clean properly.
This mince separator excels in these applications as it features our patented RE80®HT Acutex® Probe Magnets, which provide superior product-to-magnet contact and more efficient magnetic separation.
The lachrymiform (or 'tear drop') shape of the Acutex® Probe Magnets allow for very smooth transition of viscous products to move around the magnet with minimum resistance to flow. Maximum product to magnet coverage is achieved without causing leaks, blockages, and pressure problems.
The peak (or V-section) of the probe is faced towards the oncoming product stream, ensuring that collected magnetic fragments are washed to the back of the probe and safely retained until cleaning operations are underway. This feature greatly reduces the risk of recontamination caused by the impact of the product flow dislodging the collected fragments and reintroducing them back into the product stream.
