Abstract: A device for an for singulating grains based on a pressure difference comprises a chamber for receiving the grains, and a rotatable singulation element. The chamber is delimited in one direction by the singulation element and grains are transported from the chamber to a dispensing region by the singulation element. A first compressed air supply supplies compressed air to the chamber in order to generate at least one pressure difference. The singulation element has a plurality of recesses and the grains can be held in the recesses due to the pressure difference. Individualized grains are dispensed into a grain line in the dispensing region. A second compressed air supply is provided in order to prevent a flow of air out of the chamber into the grain line and in order to transport the grains through the grain line in an accelerated manner by the compressed air.
