Abstract

High performance grains dryer fed by a heat generating source through hot air stabilizers linked to the drying column and the dryer tower, which is constituted by a series of parallel ducts, between which passes the downstream vertical now of grains, unevenly set in oblique alignment and fed so that each duct that operates as hot air entry presents laterally adjacent ducts that operate as used air exit, causing the appearance of air lows crossed to the right, crossed to the left, concurrent and countercurrent, the adopted air flows varying along the drying tower, decreasing along the same, while the perimeter walls of the dryer are equipped with particles separators that generate air flow to the dryer and separate the particles expelled by the drying process, re-conducting them to the burning in the furnace through return ducts. The drying tower is assembled on a hydraulic discharge mechanism, which controls the speed of the grains inside the dryer, releasing the grains in short cycles, eliminating self-classification and providing a uniform discharge of the product, the bottom presenting windows for the reversion of the air flow at the grains discharge.
