2. SAFETY CONTINUOUS MIXED-FLOW GRAIN DRYER WITH COMMANDER CONTROL SYSTEM

7713395 R2 9
2.4. Grain Dryer Safety
• Do not overheat grain or operate the dryer temperature too high. Keep the maximum
plenum temperature not more than the maximum set point temperature.
• Be cautious of spontaneous combustion when working with oil seeds.
• Grain dust is a fire hazard. Keep all areas (including areas under the perforated floors) free
from dust and fines.
• Clean out the dryer after using to remove grain dust, husks, and other materials.
• Screen grain before it goes into a bin to help prevent dust and trash buildup. Using a grain
spreader will help distribute dust/fines.
• Ventilate, purge all contaminates, and allow burner, and drying areas to cool inside the
heater, in the heater area and the dryer area before any persons enter these areas.
• Do not remove covers, touch, or service internal components during operation.
• Do not install or combine with products from other manufacturers. The design and safety
features may not be compatible.
• Do not store or use gasoline or other flammable vapors and liquids in the vicinity of dryer.
• Do not use the dryer where a high concentration of grain dust or flammable liquids or
vapors exist, such as milled grain dust.
• Use the dryer only with the gas types intended, connecting alternate fuel sources to the
dryer can result in fires.
• Shut off and lock out or disconnect power and close valve at gas source before inspecting or
servicing the heater, or when not in use.
• Keep away from fan impeller/blade; high suction can pull a person toward the inlet. Contact
with an unguarded impeller/blade will cause severe injury.
• Keep the fan inlet screen in place at all times.
• Remove foreign material from the fan inlet before operating.
• Do not operate the fan if there is excessive vibration or noise.
• When the power is locked out, fans can still be dangerous because of potential
“windmilling.” Always block the impeller/blade before working on any moving parts.
In case of a dryer fire:
• Turn off gas at the heater and supply tank.
• Shut off and lock electrical power.
• Seal the aeration fan inlet and any other opening to smother
the fire.
• Evacuate all personnel from the area.
• Call the fire department.

If You Smell Gas:
• Turn off gas at the source if possible.
• Do not try to light or relight any appliance.
• Extinguish any flames and remove any sources of ignition from the vicinity of the bin.
• Do not touch any electrical switch.
• Evacuate all personnel from the vicinity of the source of the smell.
• Immediately call your gas supplier. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
2.6. Guards Safety
• Keep guards in place. Do not operate with guard removed.
• Do not walk on, step on, or damage guards.
• Lock out power before removing a guard.
• Ensure all guards are replaced after performing maintenance.

Inspect the power source(s) before using and know how to shut down in an emergency.
Whenever you service or adjust your equipment, make sure you shut down your power
source and gas supply and follow lockout and tagout procedures to prevent inadvertent
start-up and hazardous energy release. Know the procedure(s) that applies to your
equipment from the following power sources.
For example:
WARNING
• De-energize, block, and dissipate all sources of hazardous energy.
• Lock out and tag out all forms of hazardous energy.
• Ensure that only 1 key exists for each assigned lock, and that you are the only one that holds that key.
• After verifying all energy sources are de-energized, service or maintenance may be performed.
• Ensure that all personnel are clear before turning on power to equipment.

3. Features
Read this section to familiarize yourself with the basic component names and functions of the grain
dryer.
3.1. General Design Criteria
Note
Grain dryer design is based on load factors. If you wish to add more sections to your dryer in the future,
please let NECO know when you place your order so it will be designed to fit to your expanding needs.
3.1.1 Tier Information
• A tier is a set of parts that make up ONE layer of the dryer (also called body section).
• The top four tiers on all dryers are made up of 18 gauge material.
• The tiers below the 18 gauge tiers will be made of heavier materials, based on the required strength of that
dryer configuration.
3.1.2 Body Section Information
• An assembled dryer section may be made up of:
– 3 to 7 tiers
– a blower
– a burner
• The lowest body section is attached to the dryer frame and includes the entrance door.
3.1.3 Standard Lengths

3.1.5 Dryer Model Number
The dryer model number provides information on the dryer length and capacity.
• The two digits after “D" are the dryer length.
• Multiply the remaining digits by 10 to determine the approximate bushel capacity for corn. In this example:
40 x 10 = 400 bushels
Example: D 16 60
•16 indicates this model is a 16 foot long dryer
•60 indicates this model has a capacity of 60 x 10 = 600 bushels
Using the same process, a model D32500 would be a 32 foot long dryer with an approximate capacity of 5,000
bushels.
