ABSTRACT
Bulk storage bins of concrete, steel, or wood are common to the grain industry. Such bins are also essential in the seed industry for bulk storage of seed. The only difference in bulk grain bins and bulk seed storage bins is the need for smooth inside surfaces which offer fewer places where seed can lodge, and make the bins easier to clean when changing seed lots. And, facilities for filling and emptying the bins must minimize mechanical damage to seed. Storage bins are treated in greater detail elsewhere in this manual.
