The problem
Wernsing came to us and told us that they currently had 12 optical sorters and 10 employees who checked the potatoes after they were categorized as “good product” by the optical sorters. The sorting quality had an accuracy of about 60%. They wanted to get the sorting quality up to > 90% and this without any manual inspection. We gladly accepted this challenge and a development process followed in which we placed one optical sorter in the line next to the current installation for a null measurement.
From day one, our sorter performed much better and we concluded that with a number of small optimizations we could halve the number of sorting machines needed and also ensure that they would not need 10 employees but only one operator.
The solution
Finally, we installed 6 optical sorting machines including an infeed system at Wernsing Feinkost GmbH. An important factor to achieve the set requirements was not the use of the highly accurate vision software but mainly the combination of this software with our philosophy regarding the ejection of different potatoes. Where other suppliers try to separate the bad (read: waste) product from the good product flow, we separate both categories.
This means that we not only have a separate exit for the bad product but also a separate exit for the good product. This means that one action is required to sort both good and bad products, which results in a minimum chance of product flow mixing (good flow and waste flow).
The result
After a year in production, Wernsing Feinkost GmbH is still working without any manual inspection and the quality (accuracy >95%!) is higher than ever before. The six optical sorters that we have delivered are functioning to full satisfaction and even the amount of maintenance and downtime has decreased in comparison to the original situation. In short, our cooperation has worked out well for both parties and will only be further strengthened in the coming years with other great projects!
‘’Without Marcelissen, we would not have been able to achieve this cost reduction and quality gain. This way we remain the leader in the market for high-quality potato products!’’
More cases
Del Monte Greece
Del Monte Greece, a key player in the peach processing industry, implemented Marcelissen's Sliver Remover to enhance production efficiency and product quality. With its minimal maintenance requirements and precision sorting capabilities, the Sliver Remover significantly improved Del Monte's operations, garnering high satisfaction and potentially influencing peach processing practices across the region.
Impact
Not only has Wernsing Feinkost GmbH been able to increase product quality by achieving extremely accurate sorting, but in the process they have also been able to deploy 10 employees elsewhere in the company to increase efficiency in other departments. In addition, they can also use the data collected by the optical sorting machines to assess the general potato quality and take action if necessary.
In short, by working together and learning from each other, not only has Wernsing Feinkost GmbH created an extremely efficient production line with high product quality, but we have also been able to develop the most accurate optical sorting machine for (un)peeled potatoes!
