OPERATION: Seed from the teed box is distributed over the full-width adjustable-pitch auxiliary scalper screen by a revolving feed roll. |

(1) At this point the seed is subjected to an adjustable front suction. (2) which lifts out light impurities and carries them to an air settling chamber (3) Heavier air liftings drop into the front air liftings conveyor and are discharged to the side or fed to an optional FRC conveyor unit (4) which discharges to the rear waste chute. (10) Dust and fine impurities are discharged by the centrally-located fan (14) to a dust collector. The aspirated seed is fed to the head of the adjustable-pitch auxiliary scalping screen (5) Coarse impurities are tailed off and discharged from the front of the seed cleaner. After passing through the auxiliary scalper screen, the seed flows onto the mail screen (6) which removes impurities larger than the seed and discharges them through the side discharge trough (15) |
The second main screen (7) more closely sizes the seed being processed and eliminates additional impurities through the side discharge trough. (15) The seed flows down the seed screen (8) where dirt, sand, small weed seeds and shrunken or immature kernels pass though to the pan and are discharged into the single point conveyor. (16) Seed retained on the seed screen (8) is discharged into the full-width tail aspirating leg. (11) Powerful air suction again, and more selectively, removes light impurities, carrying them to the rear settling chamber. (12) Dust and chaff are drawn to the fan and discharged; heavier impurities are discharged to the rear waste chute (10) |
