Autonomous equipment for separation of seeds from soil samples CSIC, through INIA-CSIC, has developed a device with application in research and studies on soil seed banks. It is a system for the autonomous separation of seeds from soil samples that increases the efficiency in the process of extracting seeds by washing and sieving, since, until now, said extraction has been carried out manually, being a long, cumbersome and susceptible to handling errors process.
Companies from the agricultural, environmental sciences and ecology sectors interested in the development, manufacture and commercial exploitation of the device are sought

More efficient extraction of seeds from the soil
Plan view of the extraction device The device consists of a separating mechanism partially arranged inside a tank containing a separating liquid. Said mechanism rotates around its own axis by the action of an electric actuator and integrates tubular containers with openings at both ends, in which metal mesh filters with a certain light are incorporated so that the seeds do not escape from the container during the rotating movement.
The soil sample with seeds, plant remains and sand is housed inside the containers, so that, due to the effect of the agitation produced by the rotation together with the immersion in the separating liquid of the tank and thanks to the metal mesh filter incorporated in said containers, the seeds are separated from the rest of the inert elements of the soil sample, remaining inside the containers, while the rest of the inert elements remain at the bottom of the tank.
