摘要

The device has a perforated disk (20) for separation of seeds by pressure difference between two sides of the disk. The perforated disk is assigned to a pressure difference temporary abolition device at multiple places of the disk. The perforated disk with movable blower elements (32) is connected to a dosing disk (10) for temporary abolition of the pressure difference at the places of the dosing disk. The blower elements are provided in a serrated lock washer (30) and are manufactured of -elastic material. An independent claim is also included for a method for separation of or granular materials such as seeds and fertilizer.
