Sugar & Salt

Both sugar and salt will become sticky when moisture is present. Therefore it is very important that the magnet is configured to enable swift and effective cleaning of residual product from the magnet surface, whilst still remaining hygienic.

There are many conventional-type grate systems available including designs where multiple bars are cleaned by pulling through a common wiper plate and wiper seals or sleeves.

However, history shows that these can be very troublesome, especially on product such as sugar where jamming of the cleaning action regularly occurs due to sticky residue.

In addition, sleeve type magnets do not comply with the current HACCP International Standard due to the hygiene risk (product captured between the bar and sleeve) and reduction in magnet strength on outer sleeves.

Magnattack® have developed easy-clean systems where quick, effective cleaning is achieved and collections can be properly quantified. Easy cleaning of individual bars (such as the Rapidclean® system) allows for tight-fitting wiper seals, effective removal of metal and residual product, and efficient quantifying of collected metals.

When transferred via pneumatic blowlines or vacuum lines, sugar and salt becomes very abrasive and is prone to leaving hard, sticky residue on the surface of anything that impinges on the flow of the product.

The use of bullet magnets is a conventional method for extracting metal from these types of applications. However, these rarely exceed 6 - 7,000 gauss when used in blowlines and are therefore difficult to clean.

THE SOLUTION: SPHERICAL BLOWLINE MAGNETS

• Easily cleaned.
• Aerodynamically shaped to avoid build-up of material.
• Certified by HACCP International.
• Hygienic – complies with HACCP International Food Safety Standard 0909MAGSEP 1-2010.

Liquid sugar and brine is very sticky and often viscous, so this application needs careful consideration when selecting the right magnet for the job.

Conventional methods of metal extraction in liquids include flat plate magnets in a housing where the magnet plates are positioned either side of the product flow, and multi-finger style pot magnets with multiple magnetic fingers protruding into the flow of product. Whilst both of these methods have had some success, food safety is now a much greater concern and so more consideration must be given to more effective methods. The plate style system usually does not achieve the desired product-to-magnet coverage needed for maximum extraction and retention of weakly magnetic fragments. This design is better suited to collection of nuts, bolts, and larger tramp material.

THE SOLUTION: LIQUID PRESSURE PIPELINE MAGNETS

• Non-leaking design.
• Easily cleaned.
• Quickly cleaned.
• Hygienic.
• +80% coverage to product.
• Compliant with current HACCP International Food Safety Standard 0909MAGSEP 1-2010.
