The stones separator is used to make the dry selection of hazelnuts or rounded nuts from impurities like small branches, empty products, ground, leaves etc. The produce can be loaded by a conveyor belt and/or a bucket elevator, the separator fan makes the first cleaning of the product, removing the lightest impurities. Inside there are two or more disks, which rotating, permit to the nuts to roll outwards and to fall at the bottom of the chamber; the stones stay on the flat part of the disk, and then they are removed by a clasp.
We manufacture systems until 10 disks and it is possible to apply, on demand, a rotary screen which carries out the pre - cleaning of the product (see separator fan). These machines can also be built for industrial uses, until a working capacity of more than 6000 Kg / hour.
