Trieur (Triage)
The fifth cleaning step separates the different types of grains. In a trieur, a rotating drum with indentations in its sides, the cereals are rotated. The indentations are made to exactly catch the grains that have to be collected. Grains that do not fit exactly (being either too big or too small) drop from the slot. The desired grain kernels remain in place longer, and then fall into a collecting tray, which is a stationary part in the middle of the drum. The remaining grains are used for different products, for example, for another meal or flour type, or in the animal feed industry. The trieur is not used if a mix of different types of cereals is purposely made, because then this step would separate the grains again.
