Process of the selection of a sugar beet seeds living (those which are able to germinate) in the seeds separating dead (unable to germinate) resting on the lids of seeds detachment. In this dives in water, the seeds living absorb a great deal of water and expand appreciable manner, while the seeds are dead and does not expand as slightly because they absorb less water. This expansion of the seeds alive after absorption of water to the fact that their lids, closely ajustes on the outer envelopes of the fruit, become loans be seconded. When the vibrations mechanical are implemented in a mixture of fruit impregnated of water, only the foils of the fruit is easily off dilated. This makes it possible to obtain effective in the seeds, living in extracting the mixture of the fruit, the lids are seconded.
