Why
hasn't someone made this before?
 DMC
recognized the need for more efficient dryer controls. A solution
was visualized and DMC went after it. Five years of research
and development went into making a drying system control unparalleled
anywhere. Unique electronic circuitry make Calc-U-Dri the
most accurate and reliable direct moisture sensing control
available for in-bin continuous flow grain drying at an affordable
price.
If you have a Grain
Flow system, there
is a Calc-U-Dri Retrofit for you. New retrofits are constantly
becoming available. For out-of-bin dryers, ask your DMC dealer
if a Calc-U-Dri retrofit is available for you.
*U.S. Patent No. 4,916,830

Special
Features:
•
On-delay timer
Three (3) seconds before the Grain Flow starts, the Calc-U-Dri
starts the take-away system, minimizing peak power loads.
•
Sensor Location
Location of the Calc-U-Dri sensor in the discharge auger makes
it the only moisture monitor that accurately checks the moisture
content of every bushel of grain being discharged. Wall mounted
sensors can monitor only in their immediate area.
•
Off-delay timer
The take-away system continues to run 20 seconds after the
Grain Flow stops discharging grain, emptying the take-away
system of grain.
•
Universal usage
Use with all grains in all environmental conditions. Adjustable
drying periods on the Calc-U-Dri allow for accurate use with
all grains in all types of weather.
•
No special equipment
Solid
State electronics eliminate the need for special equipment
or buildings to house the unit. The Calc-U-Dri is designed
to be operated in the farm environment.

The
Calc-U-Dri "Let's You Go to Bed at Night."
 Five
years of research and development have resulted in a drying
system control unparalleled anywhere. Unique electronic circuitry
make the Calc-U-Dri the most accurate and reliable direct moisture
sensing control for in-bin, continuous flow grain drying at
an affordable price.
How many times have you thought it would be nice to set the
desired grain moisture on your dryer, then walk away and not
worry about it because you know your grain will be properly
dried? Calc-U-Dri provides this assurance.
Here's
how it works:
1. Turn the power on
2. Turn all switches to automatic
3. Push start button
4. Dial desired moisture
Immediately on start up the Calc-U-Dri automatically
allows the grain to dry from 15 to 60 minutes (the operator
chooses the initial drying period depending upon the amount
of moisture to be removed from the grain). This is followed
by a two minute discharge period when grain moisture is sampled
as the grain is emptied from the bin.
 As
grain passes over the Calc-U-Dri sensor located in the discharge
tube, every bushel of grain is checked for moisture content.
If moisture is 0.3% higher than set point (the selected moisture
content set by the operator), the Calc-U-Dri goes back into
another drying period. If lower, the Calc-U-Dri allows the Grain
Flow to continue to discharge grain until moisture levels increase
to 0.3% above set point when the Calc-U-Dri stops the discharge
of grain and goes back into a drying period for additional drying.

Calc-U-Dri
Operations Flow Chart
In
the drying period, grain is dryed to the desired moisture.
This time is manually adjustable. In the sample period, the
unit will auger out grain for two minutes. At the end of the
two minute sample, the Calc-U-Dri continues to discharge grain.
Or if the grain is not dry, it selects a drying time based
on the grain moisture of the sample. If the grain is dryer
than the moisture limit set point, the Calc-U-Dri will auger
out grain until wet grain is sensed. At this time, it goes
back to the drying period.

For
added convenience add the DMC Calc-U-Dri chart recorder
• Records, in graph form, sampled and discharged grain
moisture, It is a convenient way to keep a record of grain
condition as it is being transferred.
•
Records drying intervals and lets you know how the Grain Flow
is functioning.
•
Can be placed anywhere, even in the house. No need to go outside
to check your grain drying system.
•
Comes with a weather and dust proof case. Inclimate weather,
dust or dirt are no problem.
•
Uses pressure sensitive paper. Do not worry about ink running
out. Any pointed object can be used to make notes on the paper.
You do not need a pen or pencil.
•
Records one hour per inch whether drying or discharging so
you will not get lost in the paper shuffle, but yet it is
easy to read.
•
Can be used to calculate capacity of the system for a given
time period.

This
amount will be added to or subtracted from the moisture readout.
