Pet Food Manufacturer Increases Foreign Metal Control With Magnattack

A pet food manufacturer in northern Australia has successfully increased their control over foreign metal after installing multiple Magnattack™ magnetic separation systems in their dry and wet processing lines. 

The Challenge

After a scare with abnormal amounts of metal in their lines, including a large metal piece that would have caused significant damage to their processing equipment, the customer recognized the need to increase their control over foreign metal. Like most food processing plants, this would be best achieved with both magnetic separators and metal detectors.

The customer contacted Magnattack Global and other suppliers to receive advice on the most effective magnets for removing metal from their product lines. 

The customer was concerned about 5 key factors: 

  • The magnets were compliant with current industry standards
  • How the magnets would be cleaned – must be safe and efficient
  • Performance and reliability of the magnets
  • The magnets were engineered for hydrodynamic separation – minimal blockage/flow problems 
  • Cost-effectiveness. 

The Solution

Where other suppliers quoted Multi-Finger Pot Magnets for their liquid lines, Magnattack recommended the new Emulsion & Slurry Pipeline Separators. 

The ESPS Magnets have been proven to be higher performing than Pot Magnets for several reasons including effective retention of collected magnetics, cleaning efficiency, absence of dead-zones, and hydrodynamic design. The customer agreed that while the Pot Magnets may be lower priced and provide some short term compliance, the ESPS Magnets were a more viable and cost-effective solution for the long-term as they would provide a higher magnetic separation rate and protection of their product.

Following further consultation with the customer, Magnattack were able to supply solutions that would not only provide adequate protection but also provide a long-term, structurally-sound solution that will stand them in good stead for years to come. 

The magnets were installed in a variety of locations throughout the customers’ plant, with duties including protection of downstream equipment, prior to filling, and final product security. Following best practice guidelines, magnets were also installed immediately upstream of metal detectors. 

Wet/Liquid Products

Prior to processing, RE80™ Round Nose Plate Magnets were installed on a screw conveyor discharge prior to emulsifying (chunky meat lines).

These magnets have proven more effective than standard Plate Magnets due to the addition of a +11,000 Gauss round nose at the end of the plate. The Round Nose 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.


RE80™HT Emulsion & Slurry Pipeline Separators were chosen for install in the customers wet/liquid product lines, including minced meat, raw meat chunks, and vegetable slurries. These systems feature RE80™HT Tear Drop Probe Magnets which are designed to extract and retain foreign metal fragments from thick, viscous slurries and liquids. Similar to the Separation Bar on the Round Nose Plate Magnets, collected fragments are safely moved around to the back of the Probe, out of the path of oncoming product – again, greatly reducing recontamination risks. 

The ESPS Magnets received USDA Acceptance earlier this year and, as will all Magnattack magnets, are endorsed by HACCP International. 


Dry Products

Magnattack RE80™ Probe Magnets were selected for dry product lines including milled grains and flours. These +11,000 Gauss Magnets were carefully placed to ensure maximum product stream coverage and protection. Much of the contamination captured by these magnets includes work-hardened stainless-steel and stone, as you can see in the below images. 


Satisfying Results

Several of the new magnets were installed during November 2018. Earlier this month, Magnattack technicians visited the site to validate these magnets and ensure they were performing to their maximum efficiency. 

During the site visit, Magnattack received positive feedback from the operators, who commented that “the new magnets collect a lot of metal, and are also nice and easy to clean and put back together.”

Achieving Efficient & Hygienic Magnetic Separation in Sensitive Dairy Powders

It is essential that magnets installed in sensitive dry product lines, such as dairy powders and infant formulas, are not only high-strength and efficient but are also of sanitary design.

Poorly designed magnetic separators can pose a dangerous risk to food safety and risk bacterial or metal contamination in the final product.

Recommendations For Magnets In Dairy Powder Lines

Magnattack™ Global technicians recommend that magnetic separators in powder lines;

  • Are void of internal welds and ledges that may cause build-up and entrapment of powder
  • Do not have stainless-steel sleeves on the outside of the magnet bars, as this allows for the possibility of powder being trapped between the inner magnet bar and the sleeve, presenting a serious potential hygiene risk
  • Are of sanitary design and build
  • Are compliant with USDA dairy specifications
  • Are endorsed by HACCP International and designed to comply with International Food Safety Standard 0909MAGSEP 1-2010
  • Have a cleaning process that ensures the least possible intrusion to product zone and does not require excess human intervention to access for cleaning
  • Are designed to prevent build-up and blockage of the product stream, and
  • If of automatic or self-cleaning operation, are designed to prevent build-up or binding of cleaning mechanisms and enable cleaning during operation with minimum food safety risk while the magnet is withdrawn

For maximum metal fragment control, it is recommended that magnets are installed in the following critical locations:

  • Incoming ingredients and bulk intakes
  • Prior to critical processing equipment
  • Discharge of processing equipment and blenders
  • Prior to metal detectors
  • Immediately upstream of packing and bulker filling

Magnattack™ Global has developed a range of USDA Dairy Accepted magnetic separators that are suitable for such applications. The range includes carefully designed models of RE80™ Mag-Ram™ Self-Cleaning Grate Magnets, RE80™ Rapidclean™ Grate Magnets, and RE80™ Powder Transfer Magnets. The RE80™ Emulsion & Slurry Pipeline Magnet has also received USDA Dairy Acceptance for liquid lines.

Overview of USDA-Accepted Magnets For Efficient Magnetic Separation

The Magnattack™ Global range of USDA-Dairy Accepted magnets have been engineered to effectively control presence of weakly-magnetic material, including work-hardened stainless-steel in product lines such milk, infant formulas, pharmaceutical powders, lactose powders, and other similar products.

“USDA Dairy Acceptance offers peace of mind to dairy and critical hygiene customers showing we’ve taken extensive measures to ensure engineering, sanitary design, and execution of our magnetic separation equipment, and to support in every way our customers ultimate goal of maintaining and improving food safety and risk reduction.”

Kevin Baker, Director of Magnattack Global.

The Mag-Ram™ Self-Cleaning Separator is an automatic self-cleaning grate magnet that requires zero human interaction in the product zone for cleaning.

This design is a highly sanitary and heavy-duty magnet that is usually installed prior to metal detectors and packing, or in high/hard-to-reach locations. It is becoming increasingly popular in food industry applications due to its ability to clean during production, with minimal reduction in magnet presence in the food zone.


The Rapidclean™ Grate Magnet is an advanced alternative to conventional grate-in-housing designs.

Two key features of the Rapidclean™ are that the magnets must be completely removed from the product zone before cleaning can be carried out and the Rapidclean™ Cleaning Tools enable efficient and safe removal of collected fragments without hand contact. These are advantageous in that they greatly reduce recontamination risks and, unlike many other designs where all the magnets are pulled through comment wipers, the Rapidclean™ design allows for visual inspection of the magnet bars prior to return to the product flow area.


The Powder Transfer Magnet (PTM) incorporates key design features of the Spherical Pneumatic Transfer Magnet, providing highly efficient separation of metal fragments without experiencing bulk density or blockage problems. The separator features Magnattack™ RE80™ Tear Drop Probes for improved separation efficiency, aerodynamics, and optimum extraction of foreign metal contamination. The PTM can be installed in vertical installations of pneumatic transfer lines, 3”-6” in diameter.


The recently-released Emulsion & Slurry Pipeline Separator (ESPS) is a breakthrough in efficient magnetic separation in viscous dairy liquid lines.

The ESPS can be installed in horizontal, sloping, and vertical pipelines, sized 1” – 6”. RE80™HT Tear Drop Probes allow for very smooth transition of viscous products around the magnet with minimum resistance to flow allowing for the retention of the collected magnetics behind the magnet away from the possibility of dislodgment by the flow of product. Maximum product to magnet coverage is achieved without causing leaks, blockages, and pressure problems.

5 Sanitary Advantages of The Mag-Ram Self-Cleaning Grate Magnet

With an increased focus on food safety and product purity in the industry, and with regulations such as FSMA becoming more stringent, it is essential that your processing equipment and magnetic separators are of sanitary design. 

Most magnetic separators used in the food industry are of manual clean design, and this can be the cause of some sanitary concern especially if they are not being cleaned adequality or frequently. The Mag-Ram Automatic Self-Cleaning Grate Magnet is an answer to such concerns. 

These are 5 of the sanitary advantages of the Mag-Ram Magnetic Separator.

Mag-Ram Sanitary Advantage 1: Frequent automatic cleaning 

The Mag-Ram’s ability to frequently self-clean before, during, and after production runs reduces risk of operator error and prevents contaminants from building up. 

Aside from magnets, plant operators are required to monitor and clean many other pieces of equipment…and sometimes there are hundreds! A simple operator error, such as forgetting to clean a magnet or not cleaning a magnet properly, can result in a build-up of collected contaminants, shorting-out, and recontamination of the product stream. 

Mag-Ram Sanitary Advantage 2: HACCP International and USDA dairy accepted design  

Like all Magnattack RE80 Magnetic Separators, the Mag-Ram is certified by HACCP International and engineered in compliance with Food Safety Standard 0909MAGSEP 1-2010. The Mag-Ram also has USDA Acceptance in the dairy category. This compliance is proof that the Magnattack range is suitable for highly sensitive food applications. 

USDA Dairy Certified Mag-Rams have internal welds removed, no cracks or crevices, no exposed threads, and other modifications that are highly attractive to dairy powder and pharmaceutical companies.

Mag-Ram Sanitary Advantage 3: Greatly reduced risk of human and bacterial contamination

Usually when operators manually clean magnetic separators, the magnets bars/drawers/probes/etc are removed outside of the product stream and the magnet housing/pipework is left open. This increases the risk of potential ingress of harmful bacteria or human contact that may not be allowed in certain situations such as infant formula powders and pharmaceutical applications.

The absence of stainless-steel sleeves in the Mag-Ram (as with all Magnattack magnets) ensures the design is sanitary and in line with current food industry standards. Here is an excerpt from our recent post on the dangers of sleeved magnets:

Magnet sleeves are a breeding ground for bugs and bacteria. Food product (or any type of contaminant for that matter) that is entrapped between the sleeve and the internal magnet can trigger mold and bacterial growth. This is a serious sanitary concern and the justification for sleeved magnet configurations being excluded from the HACCP International Food Safety Magnet Standard 0909MAGSEP 1-2010.  

Magnattack Global Article “Overcoming Challenges Experienced With Sleeved Magnets“, May 2018

Mag-Ram Sanitary Advantage 4: Enclosed Ram working mechanism

The Mag-Ram contains multiple ‘Rams’ (or bars) which retract one-by-one for cleaning to an external chamber. The working mechanism of the Ram action is fully enclosed within the cylinder to eliminate external mechanical pinch points, prevent adverse external factors such as dust and grime from reducing the mechanical efficiency, and provide a more sanitary design.

Mag-Ram Sanitary Advantage 5: Compatability with PLC control systems

The Mag-Rams compatibility with PLC control systems allows for frequent cleaning of the magnets. This ensures potential build-up of magnetic material is minimized and reduces the risk of metal re-entering the product stream.

Improving Meat Meal Value & Increasing Profitability Through Contaminant Reduction

Foreign contaminants, such as plastic and metal, can have a huge impact on the value of meat meal if they are found in the final product. In order to maintain customer confidence and increase product value, the contaminants must be removed.

Magnetic separation is a proven method of removing metal fragments from product lines, however, there are two main hurdles that renderers face:

  • Very fine wear iron and weakly magnetics
  • Ineffective magnet systems

Fine Wear Iron And Weakly Magnets

Efficient separation of very fine metal contamination is a well-known challenge in meat meal, due to being lower in magnetic mass and often weakly magnetic such as stainless-steel grades. Meat meal processing is considered a high impact process that will introduce continuous wear iron over time. These fragments are introduced via processing equipment such as hammer mills, screens, trough wear, and other moving parts. 

If effective separation of these tiny fragments is not achieved, there is a high risk that it will become a serious product security issue for the business, especially to meet pet food grade or export requirements.

Ineffective Magnet Systems

Grate magnets, both manual and self-clean designs, are one of the most popular magnet systems for dry product lines – and for good reason. If engineered correctly, grate magnets can provide the metal fragment control you need to improve product value…but on the flip side, inefficient and poorly-designed systems can have a detrimental effect.

Some problems associated with ineffective magnet systems: 

  • Obstruction to product flow and product stream blockage
  • Jamming and other cleaning difficulties
  • Stainless-steel magnet sleeves
  • Leakage of product

Ensuring that you achieve adequate product coverage without obstructing product flow is essential to achieving successful magnetic foreign material removal. There are several factors that will contribute to blockages such as substrate levels of water, fat, minerals, the range of temperature, and level of humidity.

A magnet that cannot be thoroughly cleaned will also cause obstruction to the product flow and lead to other issues such as jamming, abrasion on moving parts, and eventual failure. If not resolved, the consequences of obstruction to product flow will lead to risk of recontamination, equipment damage, or operators bypassing/isolating magnets to solve throughput issues.

Conventional magnet designs often consist of stainless-steel sleeves on the outside of magnet bars or a cleaning method that involves pulling a bank (multiple) of magnet bars through a common wiper seal. Both these methods can cause serious mechanical issues due to the nature of the rendered product, causing sticking and binding of the cleaning mechanism, which can lead to the magnet not cleaning properly and becoming a source for metal hazards itself!

Example of a multi-bar cleaning method, prone to jamming.

It is important that the magnetic separator is configured to mitigate these challenges and has a sequence of cleaning that ensures a clean magnet is presented to the product stream for efficient metal fragment separation.

Mag-Ram Technology Overcomes These Issues & Improves Product Value.

Engineered to overcome both these issues, the Mag-Ram Automatic Self-Cleaning Separator has been instrumental in improving meal quality for numerous Australian & New Zealand renderers and is now available to the North American market. This success is due to the advanced design of the system.

Image of a RE80 Mag-Ram Automatic Self-Cleaning Magnet

RE80 Mag-Ram Automatic Self-Cleaning Magnet

The Mag-Ram is a robust and versatile self-cleaning grate magnet which can clean before, during, and after production runs. Each Ram (or magnet bar) is the Ram of a pneumatic cylinder. Although the system can be configured to clean all Rams simultaneously, one of its many advantages for the rendering industry is its ability to clean one Ram at a time, at periodic intervals. This ensures that clean magnets are continuously being presented to the product flow and production does not need to stop for cleaning schedules. This is a huge advancement in improving metal fragment control, compared to magnet technology which relies on manual cleaning and risks magnets overloading and ‘shorting out’ if cleaning schedules are missed.

MBL Proteins, an Australian establishment, greatly increased their meat meal value and customer satisfaction after replacing their existing magnets with Mag-Ram Separators. In the comparison tests between their existing magnets and the Mag-Rams, the client found that the Mag-Ram provided a much leaner contaminant sample and demonstrated that it would give them tighter metal fragment control.

Further to the above results, the following unique Mag-Ram features have proven beneficial in rendering installs:

  • 13-degree twist – each magnet Ram conducts a 13-degree twist when it is retracted for cleaning. This patented feature not only helps provide maximum longevity through wear equalization of all moving parts and seals, but also helps tip the pyramid of product off the top of the Ram, which contributes to a leaner contamination sample. In addition, this feature helps to prevent product build-up and consequent blockage.

  • Dura-Slik™ Surfacing Technology – varied moisture levels, temperature, fat content, humidity, ash levels, and other factors impact the flow of rendered product. Dura-Slik Technology has anti-stick properties which keep residue build-up on the magnets to an absolute minimum, in comparison to polished or mill SS finish. This also helps to reduce abrasion to the magnets, reduce risk of demagnetization, and …tie it back to product purity.

  • Customizable cleaning-cycles – The unit can be controlled with either a PLC or stand-alone controls, to whatever parameters are needed, based on the degree or level of contamination/metal hazards in the product.

  • Efficient and effective cleaning – As previously mentioned, each magnet is the Ram of a pneumatic cylinder. This means no ‘walking’ or ‘jamming’ when attempting to clean multiple bars simultaneously, as is the case with conventional designs attempting to coordinate two air cylinders to pull a bank of magnet bars through a common wiper. The conventional cleaning method has always been troublesome and difficult to achieve success. The Mag-Ram™ design, however, permits the use of tight wiper seals which ensures the greatest versatility of control and highly efficient magnet cleaning is achieved. The Mag-Ram is also extremely hygienic, due to the absence of stainless-steel sleeves which inherently build up with unclean product residual.

Another client, Wade Phillips of JBS, comments that “Not only does it save time and labor cleaning the magnet, it is our insurance policy that the product will support our reputation and meet the customer’s expectation, especially overseas.”

The Importance of Location

Not assessing the process properly and installing magnets at incorrect locations can leave your product at risk and impact product purity and value. 

Effective magnetic separators should be installed:

  • At bulk intakes
  • Raw materials following initial screening
  • Prior to metal detectors (reduce rejection rate)
  • Prior to critical processing equipment (reduce damage and downtime for repair)
  • Bulk out loading locations and prior to packing

In terms of product purity, the most crucial location for metal fragment control is at bulk out loading and packing locations. This is usually the last chance to remove any foreign metal that may impact your product value. It is vital that the magnetic separator in this location is effective and able to operate effectively and efficiently.

Plant Risk Assessments, carried out by trained and qualified metal fragment control technicians, can be invaluable in determining areas of risk in your process lines and deciding where magnets should be installed to provide maximum risk reduction. 


In terms of increasing value and profit, it is in the renderers best interests to produce a higher quality product, and this involves decreasing the level of metal contamination. A purer, less-contaminated meat meal is more attractive to pet food manufacturers, who will pay a higher price. Low-quality product is often restricted to stock feed and may produce lower value and lower profit.

The CEO of a large Australian rendering company believes that “The Mag-Ram was instrumental in securing a long-term client that was very close to dropping us due to a number of contamination issues. Once we proved the level of control that the Mag-Ram could offer, we then become their most valuable supplier.”

By overcoming issues presented by inefficient and inadequate magnetic separators, and providing maximum foreign metal fragment control, the Mag-Ram Self Cleaning Separator has proven to be a valuable and worthwhile addition to several rendering plants around the globe.

What Will Impact The Strength Of A Magnet?

The strength of a magnet, usually measured in gauss or pull, is one factor that determines the effectiveness of a magnetic separator.

In the food industry, equipment is exposed to a variety of different temperatures, environments, products, and other circumstances that can affect the magnet’s strength. High-quality magnetic separators can retain adequate strength & effectiveness for many years, however, low-quality cheap systems can lose their strength rapidly – despite being 10,000 gauss or higher upon supply!

Loss of magnetic strength is referred to as ‘demagnetization’.

Some of the most common influences of demagnetization include:

  • Temperature,
  • Oxygen absorption,
  • Resonant vibration,
  • Thermal shock, and
  • Rough handling (such as dropping or banging).

Once a magnet’s strength is lost, it is lost forever – you cannot ‘recharge’ a magnets strength as you can a battery.

To learn more about the causes of demagnetization and how to prevent this from occurring, download our free whitepaper here.

Frequent in-house monitoring and testing, and annual HACCP-Endorsed Magnet Validations will help you keep record of your magnet’s strength and alert you to any sudden drops. Contact us here to schedule your next HACCP-Endorsed Validation.

Improving Food Safety And Profitability With Metal Fragment Control

The introduction of the new FSMA Act and the tightening of industry standards is forcing food manufacturers to be more proactive (rather than ‘reactive’) in reducing their food safety risks.  

Along with plastic and glass, metal fragments are one of the most commonly found physical hazards/contaminants in food. These may enter the product stream with incoming raw materials and result from equipment wear and tear (work-hardened stainless steel fragments). Metal contamination in the final product can have serious implications for the companies involved, including product recall, loss of customer trust, legal and financial damage, and product wastage.

Increasing foreign metal fragment control will increase your food safety level, and in turn, help increase the profitability of your business.

Here are 3 steps you can employ in your food manufacturing plant to greatly reduce risks.

1. Plant Risks Assessments/Magnet Validations

Magnet Validations (or ‘magnet audits’) assess the effectiveness of your existing magnetic separators and areas where metal contamination risks are present. Collected data is compiled into a Magnet Validation Report which contains recommendations for increasing control in medium-high risk locations.

AMR Consulting are experts in metal fragment control and magnet validations for the food industry – you can learn more about their services here.

AMR Magnet Validations help you identify areas of risk in your process lines.

2. Effective Magnetic Separators and Metal Detectors

Like metal detectors, magnetic separators are also essential in reducing metal contamination risks and increasing product security. This article discusses how they can effectively work together to control metal fragments.

The information from your current Magnet Validation Report should highlight areas where action is required to reduce risk, and this may require replacing/installing magnetic separators.

Remember, a 10,000 gauss magnet does not mean it is an effective magnet. If maximum metal fragment control is your goal, then it is crucial to also consider factors aside from magnet strength before making a purchase (find our helpful checklist here).

Contacting an experienced Magnattack technician will greatly assist in ensuring the magnets you install will provide an increased level of control.

Effective magnetic separators can work together with metal detectors to provide maximum foreign metal fragment control.

3. Frequent monitoring of magnets and metal content

Preventing metal contamination is an ongoing task. Installing magnets and forgetting about them until the next magnet audit is a mistake that has the potential to be very costly. Like most equipment, magnets need to be closely and frequently monitored.

Frequent monitoring and cleaning of your magnets will help you gain control over metal. Establish a system in your company that sets out how often magnets should be checked and cleaned, and ensure that records are kept.

  • Cleaning magnets regularly will reduce the chance of ‘shorting out’

  • Quick visual inspection of magnets during cleaning will alert you of surface damage to the magnet assembly – if magnets are damaged or dropped, their effectiveness can decrease.
  • In-house testing can alert of demagnetization

  • Records of typical metal collections will help you establish your ‘normal contamination level’ – spikes in this may indicate a problem upstream that is causing higher contamination level and higher risks
It is important to frequently monitor and clean your magnetic separators, to reduce risk of ‘shorting-out’ and re-contamination.

Increasing The Safety Of Your Food Products

Following these 3 steps and taking a practical, pro-active approach to reducing metal fragments in your process lines will greatly assist in controlling metal contamination, increasing food safety, and increasing profitability.

Magnattack Global – When Reliability Matters.

What Is ‘Shorting Out’?

In basic terms, ‘shorting-out’ is used in food industry magnetics to describe when the surface strength is ‘used up’  by the build-up of contaminants collected on the surface of the magnet. This typically occurs when a magnet has not been cleaned for an extended period of time and is holding a lot of fine contaminants.

In this state, contaminants on the outside of the build-up are not being held tightly to the magnet surface and risk being released or ‘washed’ back into the product stream (for example, if they are knocked off by oncoming product). This can be highly detrimental to final product security, with consequences being contamination in final product, recall, consumer complaints, and financial loss.

Generally, a dirty magnet is useless – regular cleaning of magnets mean a clean surface is presented to the flow of product and will always be more effective in reducing risk of metal contamination in final products.
