Goudsmit launches ‘super strong’ magnet to extract iron particles

Related tags Milk

Goudsmit Magnetic Group, which works with Heinz, Nestlè and Barry Callebaut, has launched a  EHEDG (European Hygienic Engineering & Design Group) approved magnet called Hydrohansu, which extracts tiny iron (Fe), AISI 304 and 316L particles in the dairy and chocolate industry.

The magnet can also be used for baby food and the sugar and lactose industry, as well as milk powder, coffee, soup, herbs and cocoa.

European legislation

Capture

Peter Buckley, UK sales manager, Goudsmit, told DairyReporter, the rotating magnets prevent the accumulation of fatty powders on the magnetic bars for a high level of separation.  

There was a pressing need within the industry for removal of very fine iron (Fe), AISI 304 and 316L particles in the dairy industry​,” he said.

The new magnet system is hygienically designed in accordance with the EHEDG guidelines and can be cleaned semi-automatically​.

The new magnetic separator is called Hydrohansu; this stands for Hygienic cleanflow magnet with HYDro formed housing, ROtating magnets, cleaning by HANd operation with SUper strong magnet bars and Hygienic design​.

The single-piece, hydroformed housing is made of grade 316 stainless steel and has no dead ends, sharp corners or welded seams, which prevents bacterial growth​.”   

EHEDG is a consortium of equipment manufacturers, food industries, research institutes and public health authorities to promote hygiene during the processing and packing of food products.

It supports European legislation, which demands handling, preparation processing and packaging of food is done hygienically using hygienic machinery and in hygienic premises (EC Directive 2006/42/EC for Machinery, EN 1672-2 and EN ISO 14159 Hygiene requirement). 

Removable labyrinth air lock

Hydrohansu has pneumatically operated magnet bars mounted in the door and rotates on a bearing and is fitted with a removable labyrinth air lock.

A stream of air (+0.2 bar) feeds the air lock and blows from the inside towards the product chute.

The rotating pneumatic magnet bars ensure the powerful magnetic value (11,500 gauss) is in direct contact with the product​,” added Buckley.

Tests have shown in addition to separating Fe (99%) a high percentage of the AISI 304 and 316L particles are also separated. So in future this means very tiny particles can be extracted from foodstuffs; this ensures food safety​.

Iron gets into food during the production process; products are grinded and very small particles of the machinery can get into food. But also in the bulk stage, for instance after picking cocoa or coffee beans, large metal parts are found in the products.

Filtering out the iron particles in the production stage prevents rejection of the packed and finished product after they have passed a metal detector. This saves money.

CFIA, Rennes, France

Goudsmit based in Waalre, the Netherlands, has production facilities in China and the Czech Republic and delivers to 90 countries around the world.

Our goal is to improve magnetic systems and design new ones so we can meet the requirements of customers in all kinds of industries, from food to ceramics, bulk to recycling and chemical to the metals industry​,” said Buckley.

The biggest challenge today is setting a world standard for magnets. As quality managers need to validate magnets we need a standard in which people can compare different units​.”

Goudsmit will be exhibiting Hydrohansu at the CFIA exhibition in Rennes, France, from March 8-10 2016.

The EHEDG World Congress on Hygienic Engineering & Design 2016 will take place in Herning, Denmark, from November 2-3.
