The consequences of undesired metal particles in food production processes are often unclear: from machine damage and production downtime to rejection of products and damage claims. We help food producers ensure food safety and quality processes.

Food manufacturing challenges

Populations and prosperity continue to grow worldwide. This will also increase the need for high-quality food. The food and beverage industry is meeting this need. Plants small and large produce food for the local population or for export. As a food manufacturer, you want stable output from your food production so you can meet the constant demand for products.

Prevent food contamination and recalls

One of the biggest challenges in the food industry is safeguarding food safety. You want to avoid at any costs involved in product contaminants such as foreign bodies or bacterial growth. This is because it leads to rejection or large-scale recalls, which ultimately lead to high costs and reputational damage.

Metal pollution and bacterial growth in product channels or pipelines

Foreign bodies, in the form of metal contamination, end up in food products through:

  • contaminated material input
  • machine wear and tear
  • maintenance of the production line


Metal pollution occurs from large parts measuring >50 mm, such as bolts and nuts, to very small metal particles of 30 µm.


Bacterial growth in the product channel can occur with surfaces, gaskets or transitions that are difficult to clean. Properly cleanable machines with good product flow and food-safe parts are therefore essential.

Capture iron and stainless steel contamination efficiently with a magnet

There are many types of magnetic separators, but choosing the wrong type results in too low separation efficiency. Parameters such as viscosity, type of metal pollution, density, humidity, pressure and temperature are crucial for determining the right magnetic separator for your specific process.

Guaranteeing consistent quality and output

A production line with consistent quality and output is a second major challenge. All kinds of influences can cause machines to perform poorly. This also applies to the magnets in your production line.


If a product becomes too hot or damages magnets, the separation efficiency or magnetic force may decrease. That is why it is important to have your magnets inspected frequently. This allows you to validate whether the magnets are still performing properly so that you continue to meet the international food safety standards such as HACCP and EHEDG.

Magnetic engineering design

Highest separation efficiency through 3D simulations

Magnet calculations and simulations are the basis for designing efficient magnet systems. Our simulation engineers predict magnetic performance accurately based on application and usage.


With these simulations, our design engineers develop the best magnetic separators. This ensures that magnet performance, finishing, capacity and cleaning capabilities are perfectly aligned.

No contamination due to hygienic EHEDG design

Many Goudsmit magnetic separators are EHEDG-certified. The EHEDG consortium sets the standard for the safe and high-quality production of foodstuffs. The independent consortium is authorised to certify products when they meet this standard.


If you choose one of our EHEDG-certified products, you can be sure that it meets the highest hygienic standards with the best finish. This solves the problem of food contamination in your magnetic separator.

The best finish with an HDN-certified welding department

Magnetic separators are manufactured in the company's own factory. This ensures the quality that we deliver. An important component of quality assurance is that our welders and welding robots are hygienically HDN/PED-certified.


The ‘Hygienic Design Network’ is a partnership between companies in the food industry. It establishes guidelines and standards to prevent problems in food production.


Goudsmit's welding department meets these standards and produces the highest quality and finishes in the area of hygienic and pressure-resistant welding components.

Validated magnet systems through service inspections

If you already have Goudsmit magnetic separators or another brand, we are happy to help you with the validation of your separation systems.


Our service engineers know exactly where and how to measure and carry out on-site inspections with a calibrated gauss meter. They ensure minimal interruption of your production processes and control all magnet systems at critical points. Afterwards you will receive an inspection certificate, with possible recommendations for process optimisation. This guarantees a consistent quality of your production process and product output.
