In recent months, the number of goudsmit magnets ordered by active customers in the sugar industry has increased. I asked my colleague Arthur Jonkman (Arthur Jonkman) about the reasons behind this. Arthur explained: "Until a few years ago, the European sugar market was protected. The EU artificially kept sugar prices high through import duties and production quotas. The market has recently been liberalized, and export restrictions have been lifted."

Liberalization of the sugar industry market in 2020

In 2020, sugar manufacturers were no longer restricted by production and export limits. Consequently, this also led to an increased demand for goudsmit magnets. goudsmit magnets can remove iron filings and iron particles from sugar, which is not only necessary to ensure the quality of the finished product (such as the sugar we buy in stores) but also a requirement for industrial buyers of sugar products, such as food manufacturers, who process sugar in their products. Stray iron particles can also cause machines to stop, leading to costly production downtime, which can be avoided by using magnets."

Many foods contain sugar

Arthur continued: "Whether you look at biscuits, peanut butter, jam, baby food, bread, or ketchup, you will find that they all contain sugar. Obviously, consumers do not want to find nails in a bag of sugar, but the food industry's increasingly high demands for quality now force sugar producers to filter out even the smallest particles from sugar (down to 1 microns). Otherwise, they may face damage claims or potentially be denied quality marks. Therefore, requirements are becoming increasingly stringent."

Sugar production process

Arthur said: "When sugar beets are harvested in the field, coarse iron enters the production process right from the start. To pick them out, we hang 'goudsmit capture magnets' above the feed line outside the plant. You might be surprised to learn that we often find ammunition hanging on them! The beets are then washed and cut into pieces. As they fall into the chutes, we can install 'goudsmit chute magnets' to remove the remaining visible iron pieces."goudsmitChute magnets are mainly used for free-fall and chute transport, such as removing iron impurities from powders and granules; even coarser raw materials can flow in free-fall pipes or chutes with a maximum fall angle of 45°. Chute magnets are a simple solution for removing iron contamination. You can easily install them yourself, and they have high separation efficiency. We use neodymium magnet plates by default because they are very powerful, compact, and lightweight.

Crystalline sugar has small particles

In the next step of the process, the sugar beets are boiled to produce thin and thick syrup. The thick syrup is then further boiled and centrifuged to produce crystalline sugar, which then enters the drying stage. Here, 'goudsmit cleaning magnets' are used to filter out the smallest iron particles. These are invisible to the naked eye, but removing them protects machinery, ensures good quality of finished or semi-finished products, and prevents claims."

Continuous process of sugar production

"We use goudsmit magnets in the final stage of the sugar process. Considering that sugar production is a continuous process, we cannot simply stop production whenever we wish. Therefore, the cleaning of the magnetic bars must be continuous. Otherwise, the magnets will become saturated with iron particles, reducing their efficiency. Crystalline sugar flows well, so a static system is sufficient. However, when handling powdered sugar, it tends to stick to the bars – the sugar clumps and hinders flow. We solved this problem by using goudsmit rotating magnets that keep the product in motion. We have supplied all the magnets used by the Dutch Sugar Association for many years, so we are very familiar with the problems that can arise in sugar processing. Based on our experience, we provide solutions for every situation!" goudsmit rotating clean-flow magnets are particularly suitable for filtering iron contaminants in food/pharmaceutical powders with poor flowability, as rotation prevents bridging and clogging. See also "How it works." This "Hydrohansu" type is the only rotating clean-flow system certified by EHEDG, thus meeting the strictest requirements of the pharmaceutical and food industries. It features a smooth, polished, hydroformed housing without horizontal surfaces or sharp corners/dead spots. This significantly reduces the risk of bacterial growth. Hydrohansu electromagnetic filters are semi-automatically cleaned. You can manually pull the magnetic rotor out of the product channel via a guide. The magnet is then automatically cleaned.Reference details for goudsmit magnets/usercategory/product/487662/。
