Magnets for Food Industry

Foodstuffs industry
Metal food contamination results in costly production downtime, damage claims and product recalls. Magnets remove these unwanted metal parts, such as iron, but also stainless steel AISI304 and AISI316.

Magnets for Food Industry

Tramp metal
Tramp metal parts can end up in foodstuffs such as baby food, fruit juice, frozen or canned vegetables, herbs, spices, flour, sauces, grain, powdered milk, sugar or chocolate during the production process.

Magnet systems
Strong magnetic filters remove ferrous particles and stainless steel, such as AISI304 and AISI316-L from foodstuffs.
HSMAG is engaged in continuous research into the efficacy of various magnet systems. With advanced 3D computing software and a powerful test centre, we continue to optimize our systems.
To date, most suppliers have focused on field intensity, the flux density in gauss or tesla.
Our years of experience have shown that this is not a guarantee of good metal separation.

Getting metal out of food
For ferrous particles, we optimize our magnetic bar systems to obtain the most effective bar diameter, magnet quality, pole thickness, and distance between the bars.
We know, for example, that some stainless steel particles can already be captured with an air gap of approximately 11 mm, but that the result is much better if the particles make contact with a magnetic bar.
For example, AISI316L particles can only be captured if these particles actually touch the magnetic bar.
Separation yield is extremely important for quality assurance managers.
Our product developers like to work with them to further improve our magnet systems and the separation yield.

From the history of the development of Permanent Magnetic materials, at the end of nineteenth Century the use of carbon steel, magnetic energy product (BH) max (a measure of permanent magnet storage physical quantity of the magnetic energy density (1MGOe) deficiency, while the foreign high Optoma trillion) mass production of Nd-Fe-B permanent magnetic materials, magnetic energy product has reached more than 50MGOe. In this century, the remanence Br of the material has been improved very little, and the improvement of the energy product is due to the improvement of the coercive force Hc. The coercivity increased, mainly due to that understanding of the nature and high magnet ocrystal line anisotropy compounds, and preparation technology progress.

At the beginning of twentieth Century, people mainly use carbon steel, tungsten steel, chromium and cobalt for permanent magnetic materials. At the end of the 1930s, the successful development of AlNiCo permanent magnetic materials made it possible for the large-scale application of permanent magnet materials. In 50s, the emergence of barium ferrite not only reduced the cost of permanent magnets, but also widened the application range of permanent magnets to the high frequency field. By 60s, the emergence of rare earth cobalt permanent magnets has opened up a new era for the application of permanent magnets.
