Introduction
Drying is one of the most difficult processes to control. It requires constant attention to moisture,
temperature, volume and throughput. The DM510 is ideally suited to these operations as it devotes
its attention full time to your dryer. The DM510 is a tool that helps the operators, by doing the
menial tasks and frees them to make the executive decisions about the drying process. It should be
noted that the DM510 Dryer Master only optimizes the dryer’s performance.
A good understanding of the drying process helps a great deal in understanding how the DM510
works.

Dryer Master DM510 Operations Manual
DM510 - A Brief Description
The Dryer Master DM510 from DMSI is the ideal addition to your new or existing continuous flow
grain dryer. Simple and easy to operate, the DM510 uses advanced process control to automatically
adjust your dryer discharge rate, drying grain more consistently and closer to your target moisture
level.
The DM510 is a computer control system that controls grain drying. The system comes complete
with an operator panel, sensors to measure the grain moisture and temperature entering and
exiting the dryer, a drying air temperature sensor, a moisture sensor chute with rotary feed and
remote access via internet capability. An optional printer is also available. The system uses this and
other information, to set the optimum grain discharge rate to control the moisture of the product
within a narrow tolerance.
The DM510 is capable of being monitored and controlled remotely through a web browser on your
smart phone, tablet or desktop PC through DM-Mobile. Simply connect the DM510 to an internet
enabled router and then access many of the DM510 functions through your web browser at
my.dryermaster.com. DM-Mobile can also be configured to provide you with text on alarm
messages so that you can be aware of an issue without having to be at the DM510 panel.
The DM510 provides quick payback by reducing over and under drying resulting in increased yields,
energy savings, and providing a better quality dried product.

Dryer Master DM510 Operations Manual
DM510 - How it Works
As an operator you know that grain drying is a very difficult process to control. You know that your
dryer dries faster or slower depending upon drying conditions. Ambient air temperature, wind
speed and direction, humidity, time of day, the variety of the grain being dried, and of course, the
moisture of the grain all can affect dryer operation.
The Dryer Master DM510 uses sophisticated on-line moisture measurement and moisture control
technology to overcome these difficulties. The DM510 uses specially designed on-line moisture and
temperature sensors located at the inlet and the outlet of the dryer. These sensors provide
continuous moisture and temperature readings to the computer located in the DM510 control
panel.
The computer uses this information to build an operating model of your dryer. As inlet moistures
and drying conditions change throughout the day the DM510 continuously calculates and
automatically adjusts to the optimum discharge rate for current conditions.
The DM510 has two important advantages. First in automatic mode it can continually watch the
dryer. It does not have to help unload trucks, load trains, or do any other jobs around the elevator.
The dryer receives its full attention.
Second it has the benefit of continuous moisture information from both the inlet and the outlet of
the dryer, giving it a complete picture of all the grain in the dryer, and the grain exiting the dryer.
With this information, the DM510 does not have to wait to react to changes in the outlet moisture. It
is able to adjust the discharge rate as the incoming moisture changes. For example, as wetter grain
comes into the dryer, the DM510 begins to slow down the discharge rate just as the wetter grain
reaches the hot zone.
Access to our Customer Support Centre
One of the unique benefits you the operator receive with the DM510 is access to support from the
Dryer Master Support center where DMSI has experts in the theory (application to drying),
installation and operation of the DM510. Personnel are available to answer questions about the
material in this manual and other questions you have pertaining to drying. You can call the support
center toll free from the USA or Canada at 1-888-318-0009.

System Components
The standard DM510 system includes the following components:
•DM510 control panel (with remote I/O option)
•Inlet and outlet grain moisture sensors with integrated product temperature sensors
•Calibration push button
•Drying air temperature sensor or signal converter (to access dryer’s plenum temp reading)
•Outlet moisture sensor chute with rotary feed (bypass or inline version)
•Internet connectivity capability
There is also an optional printer available for the continuous reporting of dryer operation and
results. This can be useful for customers not using the internet connectivity feature.
DM510 Control Panel including I/O:
The DM510 is a computer system complete with user interface keypad and the display screen, I/O
system and the capability to provide real time information through an internet connection to an
internet capable device. The DM510 Control Panel is typically installed in the control room close to
the dryer where it can be readily accessed by the operator. The I/O can be located remotely using a
wired connection for short distances or a wireless connection for longer distances (requires optional
wireless modems).
The Printer (Optional):
The DM510 uses the printer to provide reports such as: Continuous Averages, Hourly Summaries,
and Daily Summaries etc. These are tools that can be used to manage the total drying process.
Inlet Moisture and Temperature Sensor:
The inlet moisture and temperature sensor is installed in the flow of the product before it enters the
drying zone (hot zone) of the dryer, typically in the garner or holding bin above the hot zone.
Outlet Moisture and Temperature Sensor & Chute with Rotary Feed:
The outlet moisture and temperature sensor is installed after the exit of the dryer, typically using the
outlet moisture sensor chute with rotary feed (either the inline or bypass version).
Calibration Push Button:
The calibration button is installed near the operator sampling point for product exiting the dryer,
usually in close proximity to the outlet moisture sensor.
Drying Air Temperature Sensor or Temperature Signal Converter:
A temperature sensor is installed in the heating chamber in close proximity to the dryer’s existing
drying air temperature sensor to monitor the drying air temperature. Some systems will instead use
a temperature signal converter to use the dryer’s temperature reading.
Internet Connectivity Capability:
Connect your DM510 to an internet enabled router or wireless hotspot (via Ethernet cable) and you
access your system remotely via a desktop PC, smartphone or tablet. Simply use your browser to go
to my.dryermaster.com and login using the login information that came with your system.
