A improved silo is provided having a pair of pivoting receiver gates overlying a pair of receiver openings and a pair of pivoting discharge gates overlying a pair of discharge openings. A deformable seal is secured to the silo between the receiver openings and the receiver gates and between the discharge openings and the discharge gates. The gates are vertically adjusted by an eccentric assembly to compress the respective deformable seal for forming an air tight barrier between the respective openings and the gate.
