Grain Dryer Burner & Moisture Control

A grain dryer is a large burner blowing hot air through a column of combustible material and its fines. That is a fire risk requiring active management, and dryer fires spread to the storage they are attached to. The moisture control is the other half: dry the grain too little and it spoils in storage, too much and you have paid energy to destroy weight you sell by.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Inspect and clean the burner, flame sensor and gas train; leak-test connections
  2. Verify moisture control calibration against a reference sample
  3. Clean fans, screens and plenum of accumulated fines — a primary fire source
  4. Test high-temperature limits and emergency shutdown
  5. Inspect discharge auger, bearings and drive
  6. Confirm fire suppression access and that no fines have accumulated in ducts

Why This PM Exists

A grain dryer is a large burner blowing hot air through a column of combustible material and its fines. That is a fire risk requiring active management, and dryer fires spread to the storage they are attached to. The moisture control is the other half: dry the grain too little and it spoils in storage, too much and you have paid energy to destroy weight you sell by.

What Skipping It Looks Like

Fines accumulate in plenums, screens and ducts and become the fuel path. Burner faults produce uneven drying that leaves wet pockets in an otherwise dry bin — the classic setup for spoilage, crusting and the bridged grain that later kills someone during bin entry. An uncalibrated moisture sensor makes every drying decision wrong in the same direction all season.

Setting the interval

Annually before the drying season, with fines cleared continuously during it. Verify the moisture sensor against oven-tested reference samples rather than trusting the display — the whole economics of drying depend on that one number.

Common Questions

How often should this PM run?
Annual. Annually before the drying season, with fines cleared continuously during it. Verify the moisture sensor against oven-tested reference samples rather than trusting the display — the whole economics of drying depend on that one number.
How long does it take?
Budget about 3.0 hours for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
Fines accumulate in plenums, screens and ducts and become the fuel path. Burner faults produce uneven drying that leaves wet pockets in an otherwise dry bin — the classic setup for spoilage, crusting and the bridged grain that later kills someone during bin entry.
