15 Magnetic Liquids Traps Keep Orange Juice Metal Free

Export Success to Fruit Juice Industry in Spain

In the past 18 months, Bunting has manufactured and supplied 15 Magnetic Liquid Traps to citrus juice producers in Spain.  The magnetic separators are used to capture and remove fine iron from the juice.

Need for Magnetic Separator Protection

Magnetic-Liquid-Trap-Cartridge-md-gasketsFine iron is commonly found in most food processes.  The origin of the metal contamination is often difficult to pinpoint.  Typical sources include:

  • When the fruit is harvested.  Dirt can often have a magnetic constituent and is carried on the surface of the fruit;
  • During transportation.  Even if the fruit is collected in plastic containers, metal contamination can be introduced from the transport (eg rust, metal dust, dirt).
  • When the fruit is processed.  The process of extracting the juice from the orange or grapefruit involves several stages where the fruit is sliced and compressed.  Wear to the process equipment will produce fine metal contamination.

Extracting the Metal Contamination

Due to the fine nature of the metal contamination, high strength magnets are required.  The Bunting Magnetic Liquid Traps are fitted with Neodymium Rare Earth Tube Magnets, the strongest permanent magnets presently available.

20180424_170346
Fine iron contamination removed from fruit juice

The Magnetic Liquid Filters are designed to ensure maximum contact is made between the juice and the magnetic fields by forcing liquids through a tightly spaced grid of magnets.  Ferrous contamination is magnetically extracted from the liquid flow by the extremely powerful Rare Earth magnet design and held firmly on the surface of the Tube Magnets.

Cleaning of the Tube Magnets is simple.  On a designated frequency, determined by the level of contamination, the lid of the Magnetic Liquid Trap is removed.  The Tube Magnets are attached to the lid and are then manually wiped clean.

Dealing With Acidity

Fruit juices are naturally acidic, ranging between 2.00 and 4.80.  This level of acid has the ability to corrode standard welds.  In the Magnetic Liquid Trap, the Tube Magnets are welded onto the lid.  The welds are all to food grade standards.

20180424_161133
Welds eaten away by the acidic juice causing swelling and failure of the magnets

However, if standard welding materials are used, these will pit and corrode over time.  Eventually, the weld will be eaten away, allowing the ingress of liquid into the Tube Magnet casing.  This catastrophically damages the magnets, causing them to swell and lose their magnetic properties.  As the magnet swells, it can also split the outer casing.

Exporting Success

“We are now regularly supplying Liquid Magnetic Traps into Spain,” explained Dave Hills, Bunting’s Head of Sales.  “Our local representative has done a great job in helping the local citrus juice producers.  He understands the industry and fully understands the challenges.”

Magnetic Separator Audit for Jordans Dorset Ryvita

Inspecting Magnet Strength

Bunting engineers have conducted a thorough review of all the Magnetic Separators installed at the Jordans Dorset Ryvita plant in Poole, Dorset.  The audit was completed over three days, including attending site on Saturday to prevent any loss in production.

20180220_112713
Master Magnets Grate Magnet

Jordans Dorset Ryvita has a strong heritage of making whole grain foods and working with farmers to protect the countryside.  Ever since the brands first came together, they have continued to act on these values.

A Magnetic Separator Audit involves the inspection and test of Magnetic Separators to confirm their magnetic and physical integrity.  Commonly, such tests are conducted annually, with the final report forming part of the company’s quality audit process.

The tests in a Magnetic Separator Audit are conducted in two stages.  Stage one involved the inspection of the physical integrity of the Magnetic Separator.  This includes checking welds, and assessing any wear and damage to the surface.

Bunting Magnetics Pull Test Kit
The Spring Balance

Stage two involves testing the magnetic strength of the Magnetic Separator.  These tests are conducted by placed a magnetic ball or plate into the magnetic field and then measuring the force (in kgs) needed to remove that object from the surface of the magnetic separator.  The actual ‘gauss’ reading of a Magnetic Separator is not checked as measurement is difficult and often inaccurate.  Gauss is the is the cgs unit of measurement of magnetic flux density (or “magnetic induction”, but can be difficult to measure accurately.

Bunting Magnetics Pull Test Kit
The Magnetic Test Piece

The metal test piece is attached to the end of the Spring Balance and then placed into the magnetic field, being attracted to the magnetic pole.  The metal test piece is then pulled off the surface of the magnetic separator whilst holding the other end of the spring balance.  The amount of force needed to remove the metal test piece from the surface is recorded (in kgs).  The test is repeated three times and an average reading taken.  Similar techniques are used to test other designs of Magnetic Separators such as Plate Magnets.

Bunting Magnetics Pull Test Kit
The magnetic test piece on the surface of the Magnetic Separator

There were a wide range of designs, strengths and ages of Magnetic Separators in the production process at Jordans Dorset Ryvita.  The company had not experienced any problems due to metal contamination and requested the audit as part of their continued improvement plan.

Day one was spent assessing the location and recording the customer identity numbers of all the Magnetic Separators.  Checking the location also highlighted any health and safety issues that needed to be considered for the audit, such as working at heights.  The review identified 52 Magnetic Separators.

The physical checks of the Magnetic Separators were conducted on day two and three, on the weekend to minimise any production downtime.  Each Magnetic Separator was removed from its location and visually inspected.  Then the magnetic strength was checked using the pull test technique.  The data was recorded and presented in a detailed report with recommendations following the audit.  This report can then be used as part of the quality management system.  It also provides base data for comparison on future audits.

 

20180220_122203
Master Magnets Grate Magnet

Following the audit, the engineering team at Jordans Dorset Ryvita have made several changes to improve the removal of metal during the production process.

“Having an external review of the Magnetic Separators really helps the client,” explained Mark Harris, Bunting’s Engineer.  “We conducted the audit without any assumptions and this freedom enabled us to highlight the areas where protection was good and also focus attention where they could be improvements.  We are looking forward to working with the team at Jordans Dorset Ryvita for the long-term and providing our technical support when needed.”

Metal Contaminated Sugar Alert

Latest Metal Contamination Food Safety Alert

On the 28th July 2018, the UK Food Standards Agency released a food alert announcing ‘Tereos UK recalls Granulated Sugar due to the presence of small metal pieces‘.  This is the third report of metal being found in food reaching the consumer in 2018 after six metal contamination alerts in 2017.

Metal In Sugar

Metal enters the food manufacturing process via many different avenues.  Metal can be present in ingredients being delivered to a food processing plant and unless removed at source can enter the process and cause significant damage.  Equipment failure and wear can also lead to metal contamination and is usually removed with the right combination of magnetic separators and metal detectors.

The source of the metal contamination in the granulated sugar is presently unknown and an investigation is most likely underway.  The sugar is sold in the UK by the retailers Iceland, Poundland, and Sainsbury’s and has been recalled.  The metal contamination will be costly in terms of direct financial cost and reputation.

Getting Metal Out of Sugar

Removing metal contamination from granulated sugar is commonly achieved using Drawer Filter Magnets and Plate Magnets.  Plate Magnets are installed in chutes where the sugar flows over the surface.  Due to the small size of the sugar granules Neodymium Rare Earth Plate Magnets are preferable, producing the highest magnetic attractive force to remove small ferrous and magnetically-susceptible work-hardened stainless steel.

SC FF drawer - no tr#14B20B

Due to the potential sticky nature of the sugar, sleeved Drawer Filter Magnets are often preferred, in an easy-clean design.  The Rare Earth Tube Magnet sits tightly inside a fixed stainless steel outer tube.  Cleaning forms part of a daily maintenance schedule, with the Tube Magnets being withdrawn from the sleeves to drag and deposit metal contamination in a discharge chute.

Magnetic Separation Audits

Bunting engineers conduct regular Magnetic Separation Audits at many food manufacturing plants.  An audit involves the visual and physical inspection of every magnetic separator in a plant to check on the location, suitability integrity (ie checking welds and for wear), and magnetic strength (which can deteriorate with excessive heat, weld damage, or if dropped).  In April three Magnetic Audits were conducted and highlighted a number of issues that have since been addressed.

3 Magnet Audits Conducted For Food Safety

Testing Magnetic Separators in Food Processing Plants

In one week, we have conducted Magnetic Separation Audits at three separate UK food processing plants.  The audits form part of the quality management system of each company and are used for both internal and external food quality and safety assessments.

A Magnetic Separation Audit involves the physical testing and inspection of all Magnetic Separators.

Physically Testing the Magnetic Strength

The first part of the inspection assesses the magnetic strength.  This involves using a Pull Test Kit which includes a spring balance and various sizes and shapes of magnetically susceptible steel test pieces.  A Gauss Meter is not used as the readings can be inaccurate and variable.  The physical test involves placing the steel test piece on the surface of the magnet (on a magnetic pole) and measuring the amount of force (in kgs) that is needed to remove the item from the surface of the magnet.  This is then repeated and an average reading recorded.

Visually Assessing the Magnet

The second set of tests involve the visual inspection of the Magnetic Separators and we are checking for:

  • The amount of metal contamination captured by the Magnet;
  • Signs of damage or wear;
  • Weld integrity;
  • Fixings and any related safety issues (e.g. missing restraining nuts);
  • Cleaning regimes and ease of cleaning;

Findings

In the three recent audits there were a number of findings including:

  • Magnetic Separators were in locations where it was extremely difficult to clean and may be considered a safety risk;
  • Welds on a Magnetic Separator had been eaten away by the acidic product resulting in liquid penetrating the Tube Magnet.  This caused the magnets to expand within the stainless steel casing and also destroyed the magnetic field;
  • Damaged Tube Magnets
    Tube Magnets where the welds have failed and liquid has seeped inside the stainless steel casing causing the magnets to expand and lose all magnetic strength
  • The magnetic strength of some Magnetic Separators (especially those that had been installed for some time) was very poor and the level of separation would be minimal;
  • In some locations, Magnetic Separators had been removed from the process but were still registered in the system;
  • The positioning of some Magnetic Separators could be changed to improve the metal separation performance;

Action

Following the Magnetic Separation Audit, a full report, with all the test results, is written and submitted with recommendations.  This then forms part of the food processing company’s internal quality audit system and is refereed to when there are inspections from external third parties and customers.  Commonly the audit is repeated on a annual basis using the same test parameters.

Similar audits are also undertaken in other industries including Plastics Production and Recycling.  An annual health check ensures that the Magnetic Separators are performing to their maximum potential and achieving the separation goals for which they were originally installed.

6 Metal in Food Safety Scares in 2017

UK Food Standards Agency Reports 6 Metal-in-Food Problems in 2017

Six warnings of UK food being contaminated with metal fragments were reported by the UK Food Standards Agency in 2017.  The food safety warnings ranged from sweets to meat products.

Metal In Food Safety Warnings 2017

Greencore recalled various brands of Chicken and Bacon Caesar Wraps because of concerns that the products contained metal fragments (20 December 2017).  Greencore, as precautionary measure, recalled various brands of Chicken and Bacon Caesar Wraps.  The products, manufactured by Greencore, were sold in Aldi, Co-op Food and Morrisons retail stores.

Athole Tablet Ltd recalled tablet products because of possible contamination by small pieces of metal (31 August 2017).

William Santus & Co recalled Uncle Joe’s Liquorice & Aniseed Extra Strong Mints (35g tins) as there were concerns that the sweets may have contained small pieces of metal (15 May 2017).

Morrisons recalled Trimmed Beans because of the reported presence of small pieces of metal (20 April 2017).

Metal Found In Morrisons Green Beans

Quorn Foods Ltd recalled a batch of its frozen Quorn Meat Free Mince because of the presence of small pieces of metal (2 March 2017).  The affected product was only on sale at Tesco from 27 February 2017 to 1 March 2017.

Lotus Bakeries UK Ltd recalled Lotus Biscoff Crunchy Biscuit Spread because of small metal contamination concerns (2 March 2017).  This product was sold at Tesco, Sainsbury’s, Morrisons, Asda, Waitrose, Ocado and Nisa stores.  In addition, batch number 7005109 with ‘best before’ date 5 February 2018 has also been sold through East End Foods.

How Does Metal Get Into Food?

Metal In Food-1136All of the foods listed have been processed and it is during that process that metal can contaminate the product.  Food entering a process plant will potentially go through stages of washing, size reduction (e.g. cutting, mashing, slicing), mixing, forming, cooking and packaging.  Metal can be introduced from the wear or failure of processing equipment, or through human error.  In fact, it is not uncommon for metal to contaminate food.  However, it is unusual that metal contaminated food reaches the end consumer.

All food companies use a combination of Magnetic Separators and Metal Detectors to separate and detect the metal.  When metal contaminated products are found to reach the consumer, it can be concluded that this safety equipment failed.

Reviewing the performance of the Magnetic Separators and Metal Detectors on a regular basis is important to ensure that any metal contamination problem is identified and dealt with at the factory.  Regular audits will check the integrity of the Magnetic Separators, assessing and recording the magnetic strength and reassessing the location.  Audits for Metal Detectors will check the application, assessing detection sensitivities.

Often such audits find that changes in the process or product (including packaging) mean that the performance of the Magnetic Separators and Metal Detectors is no longer optimised.

Thankfully, metal in food safety alerts remain relatively infrequent in the UK, although each one causes significant financial and reputation damage to the producer and food retailer.

Fish Cakes Contaminated with Metal

Youngs Seafood Recalls Metal and Plastic Contaminated Fish Cakes 

In February 2018, Young’s Seafood Ltd recalled its Chip Shop Fish Cakes 6 pack due to the possible presence of pieces of metal and plastic in some packs.  The presence of metal and plastic makes this product unsafe to eat and presents a safety risk. The affected product is sold in some Farmfoods and Heron Foods stores.

Youngs is a leading British producer and distributor of frozen, fresh, and chilled seafood, supplying approximately 40% of all the fish eaten in the United Kingdom every year.  However, this product recall damages their brand and customer confidence.

Where Does Metal Contamination Come From?

Metal contamination is commonly found in food processing plants.  It can be present in the food or ingredients delivered to the processing plant, or introduced during the production process.

Food producers use a combination of Magnetic Separators and Metal Detectors to ensure that the metal contamination is removed before the final packaged food is despatched to supermarkets and sales outlets.

So How Could This Latest Food Scare Happen?

Youngs is not the first or last major food producer to face a product recall due to metal contamination.  Most food producers have installed suitable Magnetic Separators and Metal Detectors.  However, often the contamination issue is a result of old equipment no longer adequate for the application, a failure of equipment, or a change in the process.

Magnetic Separators do not lose magnetic strength over time unless they are damaged or subjected to high temperatures.  However, it is important to annually check the magnetic strength and integrity of the Magnetic Separators.  This can be easily done using a Magnetic Pull Test Kit as part of a Magnetic Separator Audit.

Bunting Magnetics Pull Test Kit

The Magnetic Separator Audit also reviews changes in the production process and may propose the relocation of some equipment to ensure that maximum protection is maintained.

Metal Detectors are often used later in the process, once the product is made and after packaging.  The settings of the Metal Detector need to be regularly checked, especially if there are changes in the production process, product or packaging.  Also, settings on the Metal Detector may be accidentally altered, reducing the sensitivity and resulting in metal contamination being missed.  Again, an annual Metal Detector Audit will review the performance and settings and ensure that there is maximum protection.

Unfortunately, reports on metal contaminated food are not unusual.  Other examples include:

42 In Line Magnets Ensure Baby Food Is Metal Free

Magnetic Separators Remove Metal During Baby Food Production

A Baby Food producer based in Germany has purchased a further 14 In Line Magnetic Separators to guarantee a metal-free product.  The latest 14 In Line Magnetic Separators are in additional to 28 already supplied and installed as they equip their food manufacturing plants across Europe.

Bunting Magnetics In Line Magnet-9528In Line Magnetic Separators are designed to easily fit into an existing pneumatic or gravity fed pipeline transporting food stuffs.  Both ends are fabricated to connect with the installed pipework.  The central body of the In Line Magnet has a strong Rare Earth Neodymium Plate Magnet.

A key feature of the In Line Magnetic Separator is that there is no restriction to the product flow.  In this particular project, baby food passes through the body of the In Line Magnet and any ferrous or weakly magnetic materials are attracted by the strong magnetic field and then held against the face or the Plate Magnet.

The Plate Magnet has a tapered step, which intensifies the magnetic force and also provides an area to collect rogue metal contamination.

As the Baby Food has chucks of vegetables and meat, it was important that there was no restriction to the product flow where the food could be damaged or blockages could occur.  The Magnetic Liquid Filter, which uses Rare Earth Neodymium Tube Magnets, would not have been suitable for this application.

Bunting Magnetics In Line Magnet-9552Periodically, the captured metal is cleaned off the face of the Plate Magnet.  Access is designed to be simple and quick, with the Plate Magnet swinging away from the body on hinges.

All 42 In Line Magnetic Separators are designed for use in pneumatic pipelines up to 15 psi.  They are manufactured from Stainless Steel there are a range of standard sizes available.

Reviews of typical food processing plant layouts with suggested locations for Magnetic Separators and Metal Detectors include:

Getting Metal Out of Beer

Ideal Locations for Magnetic Separators and Metal Detectors in a Brewery

Thankfully, it is very unlikely that you will ever find a piece of metal in your glass of beer.  However, when tramp metal in the form of screws and nails is accidentally introduced during the brewing process, it damages processing equipment and can even affect the taste of the beer.  In this article we look at the best methods of ensuring that the brewing process is unaffected by tramp metal.

Bunting_Magnetics_Europe_Brewery_Plant

As with any food process, there are many locations where metal can be inadvertently introduced.  With raw materials being collected from the fields and then transported to the brewery in large trucks, contamination by metal and other materials is unavoidable.

Here we look at a typical brewery and identify where Magnetic Separators and Metal Detectors could be located to remove any metal contamination.

Location 1 – Malt In-feed Line

When the malt is delivered by truck or rail, it is commonly pneumatically transported into storage silos.  A Pneumatic In-Line Magnet and/or Metal Detector would ensure that any tramp metal in the raw material feed is removed prior to storage.

Bunting Magnetics In Line Magnet-2

A Pneumatic In-Line Magnet is designed to easily fit into a pipeline without causing any obstruction.  It has a magnetically strong Plate Magnet mounted on one side which attracts and holds any ferrous metal.  This is then manually removed on a regular frequency.

The Metal Detector identifies and then ejects any remaining metal contamination, both ferrous and non-ferrous.  As most metal contamination at this stage is ferrous, installing the Metal Detector after the In-Line Magnet reduces the amount of metal detection rejects and thus reduces the loss of product.

Location 2 – Prior to Milling

cartridge_magnetsGrate Magnets are commonly positioned in or above the in-feed hopper to the mill, especially if there has been no previous metal separation or detection.  A Grate Magnet is a series of Tube Magnets designed in a grid to fit inside a hopper.  For maximum protection of the mill, the Grate Magnet uses a set of high magnetic strength Rare Earth Neodymium Tube Magnets.  Such protection ensures that no tramp metal enters the mill where it can cause serious and expensive damage.

Location 3 – Hot Water Feed to Mash Tun

Bunting Magnetic Liquid TrapWater is a common source of metal contamination in food processing plants and is also the one in-feed material that is often overlooked.  The nature of water means that rust is common and a simple Magnetic Liquid Trap is used to attract and capture any rogue ferrous metal, even in a very fine form.  A Magnetic Liquid Trap is designed to be easily introduced into a pipeline, with flanges or any other connector.  Inside the body, high strength Rare Earth Neodymium Tube Magnets project down into the material flow, attracting and capturing any ferrous or weakly magnetic materials.  The Tube Magnets are removed from the process and manually cleaned.

Location 4 – Between Mash Tun, Lauter Tun and Brew Kettle

Magnetic Liquid Traps could also be located between the Mash Tun, Lauter Tun and Brew Kettle, especially is there has been limited protection earlier in the process.

Location 5 – Hops In-feed Line

Protection is important whenever raw materials are introduced into the process and Grate Magnets and a Quicktron Metal Detector will ensure that hops entering the brew kettle are metal-free.  This design of Metal Detector is for free-fall material.  As the material enters the metal detector, any metal is detected and then automatically rejected.  The Grate Magnet reduces the amount of material lost during the rejection process by removing any ferrous metal.

Location 6 – Between Brew Kettle and Whirlpool/Settling Tank

After the brew kettle , a Magnetic Liquid Trap, with special Neodymium magnets designed to withstand high temperatures, will provide final protection prior to settling.

Location 7 – Yeast In-feed Line

As on the hops in-feed line, a combination of a Grate Magnet and Quicktron Metal Detector will ensure that any metal does not enter the process.

Location 8 – Between Conditioning Tank and Filter

To protect the filter, a Magnetic Liquid Trap is often installed after the conditioning tank.

Location 9 – Prior to Bottling

p-TRON-GM-V2As in many food processing plants, it is good practice to install a Metal Detector (in this case a P-Tron) at the final stage of the process.  This provides a final stage of protection to ensure that any metal introduced into the process from damaged processing equipment such as the filter or in the pipes is detected and removed.

This is a typical example of a Brewing Operation.  However, each plant is unique and often a site visit is required to assess and recommend the best ways to ensure a metal-free end product.

Cases of Metal Found In Food

A Food Safety Nightmare

To mark the start of the UK’s Food Safety Week (19th – 23rd June 2017), we are looking at recent cases where there has been an issue with food safety with specific reference to metal contamination.

Metal_Physical_Hazard

Metal contamination is commonly found in foods as they are being processed.  Metal can be introduced at a number of stages including:

  • Originating in the raw food product prior to arrival at the processing plant;
  • During transportation of the foodstuffs to the processing plant;
  • In the process from process machinery wear or failure;
  • Accidentally by workers or during maintenance;

In the vast majortity of food processing plants, there will be a series of Magnetic Separators and Metal Detector to remove and identify any metal contamination prior to the finished food product leaving the factory.

However, if the Magnetic Separator or Metal Detector is not operating to the optimum efficiency, or if there are no systems to remove metal installed, then metal end up in the food product being purchased by the consumer.

Recent Metal Found In Food Cases

These are some recent cases where metal has been found in food.

  1. In May 2017, William Santus & Co announced that Uncle Joe’s Liquorice & Aniseed Extra Strong Mints (35g tins) were recalled because there were fears that the sweets may contain small pieces of metal;
  2. UK supermarket Tesco faced a ‘metal-in-food’ safety warning in March 2017 when there were fears that the vegetarian product, Quorn Meat Free Mince (300g pack), was contaminated with small bits of metal;
  3. Lotus Bakeries UK Ltd recalled Lotus Biscoff Crunchy Biscuit Spread because the product may contain small pieces of metal.  This affected most of the supermarkets in the UK in March 2017;
  4. Metal Found In Morrisons Green BeansThe food company OK Food Inc (Oklahoma, USA) recalled more than 466 tons of breaded chicken because of possible metal in the food in March 2017;
  5. In the USA, Blue Buffalo dog food had to be recalled in March 2017 after a Lakeland woman reported that she had found metal.
  6. UK supermarket Morrisons was hit by a food safety scare in April 2017, when metal wire was found in green beans;

In all cases, the cost of recalling the product was significant, but for many it was not as high as the damage to the company’s reputation.
