ABSTRACT
The problem of feeding the increasing world population can be solved by protecting already-produced grain. Storage of cereal grains is therefore critical to human survival and food security. About 900 million metric tons of grains are in storage throughout the world at any given time (Jayas et al. 1995). This represents about 40% of the total annual cereal production. Most of the world storage capacity is located in the United States (590 million tons). About 58% of this grain storage capacity is on farms and the other 42% in commercial elevators. Storage is a key step in the complex logistics of moving grain from producers to processors, and grain products from processors to consumers. The main purpose is to equilibrate supply and demand.
