An unloading system for use in a storage structure having a sidewall that contains granular stored material. A reclaiming portion is spaced from the sidewall and has a floor portion that extends from a discharge opening toward the sidewall. The floor portion of the reclaiming portion is supported above the floor of the storage structure. The reclaiming portion may move with respect to the sidewall and is isolated from movement with respect to the sidewall of the storage structure. Seals between the reclaiming portion and the sidewall prevent the stored material from bypassing the reclaiming portion so that any discharge of the stored material occurs through the discharge opening.

A system for dispensing packages from an underground storage facility is disclosed, more specifically to disclose systems for handling packages using gravity and buoyancy. An underground storage system comprises a storage facility and at least one open air fluid column. The storage facility has an above ground portion connected to a hollow underground portion with a bottom. A helical ramp extends from the above ground portion to the bottom of the storage facility. Devices are located adjacent to the helical ramp to dispense packages to the helical ramp. A conveyor is located at the bottom of the underground portion to receive packages from the helical ramp. An airlock is located adjacent to the bottom of the underground portion and is connected to a conveyor. Packages are discharged from the storage facility via the airlock.
