A new way of grading Brussels sprouts with high efficiency.
The silent, soft and precise working of the ROLOSORT is a big step forward. Any gradings can be made, from 10 to 45 mm diameter with this fully adjustable system. It's very easy to change to a different grading size. The machine has two layers of rollers; by lifting the upper layer, you can change the play between the rollers. The standard machine has 3 or 4 gradings, each with a proper conveyor belt. The machine can be built for more or less gradings.
While grading, the sprouts roll constantly to be mesured from all sides. This results in a very riliable calibration. The stainless steel rollers are all driven and stay clean. The play between the two layers of rollers can be fully adjusted by turning the knobs on top of the machine.
Just in front of the ROLOSORT, you can put a grader with rubber slice rollers to remove small leaves and undersized sprouts. The space between the rollers can be set from 2 to 20 mm.
We can build all required conveyor belts, bunkers and elevator belts to become a complete grading line.
