Abstract
A conventional grain storage bin is equipped with means for ventilation and curing the stored grain by inducing air flow through the grain in response to a pressure differential existing between the interior of the bin and the outside atmosphere. The invention provides a break-away screen at the vent constructed to break away when the pressure differential exceeds a predetermined value, thereby preventing damage to the structure; e.g., collapse of the roof, walls, etc. when the pressure differential is created by a lower pressure inside the bin.
