<AREA SHAPE=RECT COORDS="12,299,27,315" HREF="!Grain is brought from the fields by grain wagon and dumped on a conveyor, which carries it to an elevator. The elevator lifts the grain and releases it through a flow pipe into the drying unit. Here, hot forced air dries the grain. The dried grain, represented by the gold-colored areas, is moved by a conveyor to a holding bin. The grain funnels from the bin onto the elevator, which lifts it to a flow pipe at the top of the elevator. The grain then flows into the storage bin.">
<AREA SHAPE=RECT COORDS="319,301,332,316" HREF="!Farmers often store grain in hopes that the market price will rise. An automated storage system enables a farmer to ship stored grain to market quickly in case of a sudden increase in prices. To ship the stored grain, the farmer activates a conveyor at the foot of the storage bin. The conveyor removes grain from the bin and carries it to the elevator. The elevator lifts the grain and releases it into a downspout. The grain flows through the spout and into a waiting truck.">
Grain can be stored for months after harvesting if it has been dried to prevent spoilage. Many farms that store large quantities of grain have an automated system for drying the grain and for transferring it to and from storage bins. These drawings show how such a system works.<NP>
