FIELD: grain of foodstuff storages. SUBSTANCE: device has feeder funnel, spreading head made up of rows of plates arranged in parallel and coaxially, one over the other, whose surface decreases from upper plate to lower plate. Set is designed so that each plate has hole which contributes to supply of plate arraged directly below, owing to gravity forces. Lower plate can have hole to supply centre of container. Plates are set into rotation to permit delivery of solid matters separated into fractions by centrifugal forces, and at least one plate with holes, the latter (latters) being arranged at funnel outlet and before particle spreading plates. EFFECT: enlarged operating capabilities. 9 cl, 5 tbl, 6 dwg
