Drying Chamber
Enter the drying chamber and inspect each
dump hopper for obstructions that may inhibit the flow
of grain into the dump chutes. Make sure that the gap
between the discharge flow plates and the floor sheets
is a minimum of 1-1/2”. All discharge flow plates
should be adjusted evenly around the bin. Inspect each
discharge flow plate and make sure that the bottom
brackets on each flow plate have not collapsed due to
pressure from walking around the drying chamber.
Inspect the leveling bands. Make sure that all leveling
bands are installed properly and in are good shape.
