A device and a method for receiving and handing over fine-grain to coarse-grain solids from a container to a higher pressure system via a cut-off device. The device and method allow improvement of the hand-over of the solids while reliably guaranteeing the solids transport even for difficult bulk materials, high operational flexibility when used for various bulk materials and high flow rates towards the receiving container while avoiding compression of the bulk material. The device is formed from at least one vertical central tubular body (central tube) which is arranged inside the container at a distance in the direction of gravitation upstream of the cut-off device and which is open at the top and at the bottom, and by gas supply devices impinging the container bottom and/or the central tube to produce a solids flow in the central tube.
