Description

After excessive trash has been removed by scalping, debearders are used to remove awns or beards and other appendages from seed that are difficult to clean with air-screen separators. Debearders use a beater that rotates inside a steel cylinder. The beater uses projecting posts that are positioned to move the seed mass through the cylinder. Stationary posts on the steel cylinder prevent the seed mass from rotating with the horizontal shaft and provide vigorous rubbing action between the moving and stationary posts, other seed, and appendages. A weighted discharge gate controls the amount of time the seed mass remains in the unit. A debeader is a very versatile machine that has been used successfully on many types of seed. Its cleaning action is less aggressive than that of a hammermill.
