The silo has a mainly sealed storage chamber (2) with extraction device. This consists of a moveable at least partly flexible conveyor tube arrangement (5) with extractor head (4) and traversing devices (13) inside the storage chamber. These operate the extractor head to move automatically across a large area (10) of the chamber. The conveyor tube arrangement is for pneumatic conveying of bulk goods (12). It has a feed air and waste air suction tube. The silo is defined on the sides and/or the top by flexible material. The extractor head has an agitator and/or dosing device.
