System and method for removing soil from seed

An exemplary system for removing soil from seed comprises an auger portion, a centrifuge portion and/or a dryer portion. The auger portion comprises an inclined enclosure and an auger positioned within the enclosure and is configured to mix seed with a liquid, remove soil from the seed, and separate washed seed from the liquid and the removed soil. The centrifuge portion comprises at least one centrifuge having an outer drum and a rotatable inner basket positioned within the outer drum. The inner basket comprises a side wall having a plurality of apertures. The inner basket is configured to receive washed seed from the auger portion within the inner basket and to centrifugally separate additional liquid from the washed seed, the separated liquid passing through the plurality of apertures into the outer drum. The dryer portion further reduces moisture content of the seed using heat.
