There is specialized equipment designed for this purpose that one can buy or rent. Portable grain augers can be used to fill a flat-storage building by making openings in the roof or by moving the auger around inside the building. Unloading can best be accomplished by using a front end loader that either feeds the hopper of an inclined auger or directly loads grain into a truck or wagon. Pneumatic grain conveyors can also be used for filling and emptying flat storage buildings. If an above-floor aeration system will be used, the ducts should be placed inside the empty building at the correct locations first.
Aeration Cooling Cooling the grain with aeration is extremely important for proper storage.
Cool temperatures minimize mold growth, limit moisture condensation and accumulation, and control insects. If the pile is leveled, duct spacing should be about equal to the pile depth. For a long triangular-shaped pile, one duct centered under the peak and running the length of the pile may suffice. Unusual pile shapes make aeration design tricky. An experienced aeration system designer should be consulted in these cases.
