Abstract
A gravity flow apparatus that scalps off the large pieces of foreign material from grain before processing or storage. The scalper consists of an upright housing with a grain inlet at the top. The grain enters the housing and drops onto a dead head slide. The dead head slide with a flexible baffle slows the momentum of the falling grain then spreads the grain out over the slide width before it enters the screen. The slide is sloped to suit the grain's natural angle of repose and is lined with an anti-friction material for mass flow. The grain enters the full width of the screen while a second baffle stops grain from freely pouring into the foreign material discharge. The screen is adjustable to allow the grain to spread on the screen at its natural angle of repose while trash is scalped off over the screen into the trash discharge.
