ABSTRACT:
Means for reducing hoop stress in a silo cell comprising a grain tube located in the lower part of the silo cell, the wall of the grain tube having apertures at the silo base allowing entry of granular material into the grain tube, and a restrictor below the apertures restricting the material flow so that when the silo cell first discharges the material, all of that discharge is through the upper ends of the tube, downwardly through the tube and outwardly from the silo cell through valve means beyond the lower end of the tube and restrictor.
