| 摘要 |
A high capacity grain aeration apparatus (10) is provided which includes opposed, upright, tubular, ported inlet and outlet ducts (24,26) positioned within a grain bin (12) and having inlet and outlet fans (28, 30) adjacent the upper ends of the ducts (24, 26). The ducts (24, 26) preferably present smooth, uncorrugated walls (40, 44). In use, aeration air is directed through the inlet duct (24) and then transversely through the ports (42) to the interior (20) of grain bin (12). Such air flows transversely through the grain within bin (12) and is pulled upwardly through outlet duct (26) by means of outlet fan (30). Additional aeration air enters through vents (50) or the grain inlet port (47) and enters the outlet duct ports (46) by passing through the grain.
