Entrepeneur Wouter van der Beek with his new optical sorting line for onions.
Higher qualityThe entrepeneur purchased another location in the village of Tollebeek where he was faced with the choice to purchase a new sorting line. From that moment, Van der Beek began to orientate himself with the possibilities of an optical sorting line. A forty metre long optical sorting line was placed. Van der Beek chose this installation for a number of reasons. "The quality increases and can be guaranteed to stay at this level. I would like to work with chains at a more personal level with this new machine. The grower is rewarded for a good quality batch of onions. This gives him higher efficiency."
It is possible to see how the onions look from the inside on the computer. The farmer has the possibility to see his own data via the computer.
Advanced sorting lineWhile the fruit and vegetable industry has been using optical sorting machines for at least twenty years, this was never the case with onions. No one was ever in the position to develop a selection line for onions with selects by size, colour, weight and external quality. "This manner of sorting out quality problems is beneficial, especially during a season with quality problems. With traditional sorting machines, an onion that looks great from the outside can still be rotten from the inside. That was made clear again last year."
The onions are transported to a type of 'dish' where they are directed to the appropriate crate. The computer ticks the onions with flippers, that are present on every conveyor belt, in the direction of the correct dish.
