PNEG-1153 CALC-U-DRI Moisture/Matic/Manager
1. INTRODUCTION
DMC’s Calc-U-Dri Moisture/Matic is a grain drying control specifically designed for continuous
flow, out-of-bin grain dryers with an SCR control and a DC motor on the metering rolls.
flow, out-of-bin grain dryers with an SCR control and a DC motor on the metering rolls.
The Calc-U-Dri Moisture/Matic will automatically increase or decrease the speed of the metering
rolls to maintain a desired moisture content. The Moisture/Matic is available as a base unit or
with an optional chart recorder or printer for convenient record keeping.

with an optional chart recorder or printer for convenient record keeping.
The metering roll speed control potentiometer in the dryer control panel is replaced by the main
speed control in the Moisture/Matic. A DC voltmeter is provided to indicate the voltage applied
to the metering roll motor, which will change from fast, medium or slow. The speed is selected
by comparing the actual moisture of the grain being discharged from the dryer to the moisture
Set Point.
speed control in the Moisture/Matic. A DC voltmeter is provided to indicate the voltage applied
to the metering roll motor, which will change from fast, medium or slow. The speed is selected
by comparing the actual moisture of the grain being discharged from the dryer to the moisture
Set Point.
As the grain moisture increases, the Moisture/Matic will slow the metering rolls down. The slower
grain movement will increase the time the grain spends in the dryer, which will reduce the
moisture. As the moisture nears the moisture Set Point the unit will switch from slow to main
speed. As long as the grain moisture is at or near the Set Point the main speed is retained.
Should the moisture start to get dryer, the unit will switch to high speed. The three speeds are
adjustable to match the dryer to the grain that is being dried.
