At the end of 2017, the European sugar market has been liberalized, which has had a large impact on the sugar industry. According to recent figures, Antwerp is the complete sugar port. Euroports therefore takes on an important role. They have invested in their sugar terminal, at the port of Antwerp, to be able to react to the expected growth of their customers in the coming years. The storage and handling capacities were expanded to further increase the quality of the processing of the goods.
With a treatment capacity of 635.000 tons a year, Euroports is now the largest sugar terminal in Europe. To achieve this target, the screening/sieve capacity had to double. Therefore, Euroports approached Motogroup for help.
Euroports is one of the largest European port companies. The group handles more than 50 million tons of dry bulk and general cargo a year and has 26 terminals in Europe and Asia. In 2017, the company implemented a substantial upgrade of its terminal in Antwerp. For example, new unloading wells were introduced for trucks.
An unloading station for train cars and there has also been investment in metal detection and screening/sieving, so that the quality of the sugar is guaranteed. The terminal also has a licensed quality control lab and uses the latest IT-systems for monitoring the products. Motogroup renovated the installation, enabling Euroports to double its screening/sieving capacity.
Installation sieving capacity
The new installation stands, for the best part, next to the existing production hall. This was fully assembled in the first phase, so that the production shutdown was kept as minimal as possible.
In the second phase, the old screening/sieving-installation was removed and the connection was made to the new screening/sieving-installation. As a result, the shutdown was limited to just a few weeks.
Operation sugar installation
The sugar arrives in trucks or train cars and is unloaded. The white sweetener is transferred from the sugar building to the bagging building via a conveyor belt and transferred into an elevator.
This conveyor belt is 1200mm wide and can transport 600 tons of sugar per hour (the old conveyor belt was 300 tons/ hour). During the design of the conveyor belts, extra attention was paid to avoid spillage. Afterwards the sugar is transferred to a distribution valve via another conveyor belt. This valve distributes the product flow over two Spaleck screens/sieves.
The function of these two screens is to remove large lumps and contaminates from the sugar. The flip flow screens/sieves consist of double deck screens/sieves where the large material fractions are separated up to 10mm at the top and smaller fractions up to 3mm at the bottom.
The Spaleck screens/sieves consist of a dynamic frame, a fixed frame and sieve mats/belts. The relative movement of both frames with respect to each other produces a so-called “trampoline effect” of the sieve mats.
This has the advantage that the product does not stick to the mats and a high acceleration force of up to 50g on the sieve mats is possible. The sieves are six meters long, three meters high and three meters wide and each weigh 12 tons.
Afterwards, the sugar comes into contact with two by-flow magnets to take out any metal present. Finally, the product is transported back to the sugar building via conveyor belts. The fresh sugar is stored. The oversize that was removed by the sieves ends up in a big bag filling station.
When the sugar is collected, the sugar traverses the process again through the installation and is then loaded directly into trucks, train cars, big bags or 50kg bags. In other words, the pure sugar goes through the process two times to ensure that there is no more contaminates in the sugar. The installation is completely designed according to the food standard EC 1935/2004 and in accordance with the Atex 114 directive. Every part of the installation that comes into contact with the product is made in stainless steel.
