11.01.2021 Sifter incorporates magnetic separator for ATEX-approved application

Hanningfield, Rochford, UK, is an independent Essex-based family-owned business that designs and manufactures powder handling and processing equipment, primarily for the pharmaceutical industry, but also for related sectors such as food and chemicals. Working for a client within the food industry, safety was key for the end customer who sought an extra level of security to eliminate the risk of foreign body contamination.

Hanningfield installed a double-row housed grid, manufactured by Sheffield-based Eclipse Magnetics, to its Kwik-Sift centrifugal sifter to capture any fine particles of metal that may have been trapped within the agglomerated powders. Sifting hundreds of kilograms per hour, it is imperative to the client that all potential risk is removed as the application is used to process food materials, including flour, egg powder and cocoa, along with any other products that require de-lumping.  The Kwik-Sift acts as a first line of defence, capturing common foreign bodies such as plastic, elastic bands and hair.  The magnet was selected as a final security measure to capture the smaller particles of metal that the Kwik-Sift basket was unable to capture.  A Kwik-Sift and integrated magnet are used to guarantee the entire process, and usually employed before the material is processed so as to reduce the chance of a potentially scrapped batch.

The housed grid high-intensity magnetic separator has long been a top choice for foreign body removal throughout many industries, offering unsurpassed results for the removal of ultra-fine iron and para-magnetic contamination from dry, free-flowing substances such as flour, grains and sugar.

The grid magnet is fed by gravity, housed in high-grade stainless steel and is capable of removing micron-sized contaminants. It can be removed and cleaned within seconds by taking the magnetic cores from their housings and letting the contaminants simply fall away. The cleaning process takes less than 30 seconds to complete, ensuring machine downtime is kept to an absolute minimum.

Having used Eclipse Magnetics products previously, Hanningfield once again chose this supplier because of its UK location, high-quality products, experience within the food and pharmaceutical industries as well as its ability to meet the requirements of ATEX certified applications.; .
