Magnetic seed separator

It is very difficult to separate seeds with cracks or holes from undamaged seeds. The way to do that is to use iron powder and fill these imperfections in the seeds and thereby separate them. That’s why it’s important to have a Magnetic seed separator that ensures all seeds are undamaged and of the finest quality.

Get rid of damaged seeds quickly and efficiently

The Magnetic seed separator by Seed Processing Holland separates damaged seeds from undamaged ones. The seeds should first be mixed with whetted iron powder.

The seeds should then be dosed onto the unit’s conveyor belt. The magnetic roll at the end of the belt has a strong constant force, so all seeds with the iron powder will attach to the magnet and be moved to the bottom of the conveyor.

At the bottom, the damaged seeds will be released by the magnet and will be separated from the iron powder, enabling operators to re-use the powder. On the other hand, the good seeds will exit from the front of the machine, where you can collect them in a box or container.

The capacity of the Magnetic seed separator depends on the seed lot. It can separate 400 kg of cabbage seeds per hour, 100 kg of onion seeds per hour, and 80 kg of cucumber seeds per hour.
