Filter magnet keeps tomato ketchup iron free
In spite of many precautionary measures, in practice there are still metals present in tomato ketchup and juice: Goudsmit has introduced a high strength Pharma magnetic particle filter
The points where magnets or metal detectors should be used in accordance with HACCP guidelines in the production process are indicated in the flowchart.
The brochure is currently available in four languages: Dutch/German/English/French.
The products processed in the dairy industry can be divided into three categories.
First are sticky products, transported under pressure, such as yoghurt, cheese spread and desserts: for these products, Goudsmit has designed special sanitary magnetic filters that can also be placed at the intake points for fresh milk as part of the preliminary quality control.
Second are granular, powdery materials such as milk and cocoa powder, which often contain ferrous and non-ferrous metal particles: for these products, Goudsmit has designed a magnet and metal detector combined in one system.
This all-metals-catcher removes ferrous objects measuring as small as 25 microns and non-ferrous objects as small as 0.6 mm; it can also be built into a free-fall system.
The last category of products is fatty powders, which normally accumulate on magnetic bars; for these products, Goudsmit has designed a rotating magnet system in which the accumulation of products on magnetic bars is prevented.
This system removes particles as small as 25 microns.
Lastly, as a final quality control, a metal detector can be placed at the end of a packaging line, for example, for butter or cheese.
In addition to metal separation systems, the brochure also covers the hygienic metal transport of the various types of tin packaging, lids and twist-off caps that are also used in the dairy industry.
