Abstract

An improved aeration system for use with a storage structure for storing particulate material such as grain. The storage structure includes a large flexible cover which is vertically movable relative to a center vertical support. The aeration system includes a vessel adjacent the lower end of the support. Air inlet pipes extend radially outwardly from the vessel. One or more fans are in communication with the air inlet pipes to hold the cover down and to aerate the material. The cover hold down and the aeration begin during initial filling of the storage structure and continues after filling is completed. In another embodiment a second plurality of air inlet pipes extend inwardly from the cover periphery toward the support. Fans are in communication with the second plurality of air inlet pipes to aid in providing the hold down forces and in the aeration of the particulate material.
