ANTI-POLLUTION GRAIN DRYING APPARATUS

摘要

An anti-pollution grain drying apparatus comprising: a grain drying bin having a perforated floor through which hot air is blown upwardly for drying purposes; a rotary sweep mounted in the bin for counter-clockwise (CCW) sweep movement along the floor, during which its lag side continuously deposits wet grain as it rotates over the floor to form thereon a circular layer extending about 345.degree. clockwise (CW) from the lag side of the sweep to the lead side thereof while its lead side continuously retrieves dried grain from the adjacent end of said circular layer on the floor; and an anti-pollution suction system operative to remove air-borne dust, drom the dried grain being retrieved along the lead side of the sweep, and direct it into outside equipment which separates the air and dust, captures the dust and discharges the clean air into the ambient atmosphere.
