Moisture Control...

What about moisture control?
Directly measuring moisture within any grain drier is a difficult and
often costly affair. Moisture meters have to be calibrated regularly and two identical meters
will never give the same reading for the same sample. Because of this, Allmet prefer to use a
different method than direct moisture measurement. We us the exhaust air from the drier as a
measure of moisture.
How does this work?
There is a temperature sensor in the exhaust
part of the drier. This measures the temperature of the air coming directly off of the grain
being dried. Should wet grain enter the drier, the grain absorbs more of the heat from the
furnace as it is dried, and so the temperature in the exhaust section falls. The control panel
monitors this, notices the fall in exhaust temperature, realises that wetter grain has entered
the drier and so slows the discharge down accordingly so that the wet grain spends longer in the
drier.
Subsequently, should some drier grain then enter the drier, the grain will absorb less heat, the
temperature in the exhaust section will rise, the control panel will monitor this and speed up
the discharge so that the drier grain does not spend as long in the drying section of the
drier.
How accurate is this.
This is a proven method
which Allmet have used for many years and it is accurate
to within 1% of moisture.
