**Number of Stir-Ator Augers Versus Fan and Heater Sizes
The
below
and
on Page 53
charts are based on ambient air temperature of 50°F, 60% relative humidity,
16' (4.9 m) of corn and 7%-12% moisture removal (23.5%-16% final moisture). This chart is designed as a
guide only. Fan performance will vary considerably from one manufacturer to another and other factors can
change the approximate bushels per day. Choose from Stir-Ator models with two (2) or three (3) augers to
fit bins from 18' (3.5 m) to 48' (14.6 m). Each model gives you all the exclusive Stir-Ator features that can
turn a simple bin into a wet-holding tank, dryer and storage bin - all in one unit.
Heated Air (Heat Rise above Ambient Temperature-Fahrenheit) - Corn-16'
* All multiple fans are in parallel. Multiply drying rates x 0.77 for 10 point removal.
Multiply drying rates x 1.35 for 5 point removal.
All multiple fan static pressures (where multipliers are shown) fall within acceptable performance guidelines.
** Stir-Ator down auger recommendations, as shown in the chart, are for stir-dry bins only. For grain flow continuous flow drying
system application, please refer to grain flow drying chart for down auger recommendations.
