Hot Air Recirculation

 

Significantly reduce your grain drier fuel costs by using Hot Air Recirculation 

 

Save up to 24%* of your grain drier fuel costs

How Does It Work?

The grain drier fuel savings come from the reduction in the amount of fuel the drier consumes to heat the air to dry the grain.

The cooling air, from the lower levels of the grain drier, which is unsaturated and of the highest temperature, is recirculated to the hot air side of the drier and remixed with the heated air.

Depending on the drier size, 25% to 30% of the warmest air in the drier is moved by the recirculation fan along transfer ducts to an additional plenum and mixed with the freshly heated ambient air.

*The actual percentage savings on drier operating costs by using Hot Air Recirculation can be significant and will vary based on:

  1. Hot air and ambient air temperature
  2. Crop type and moisture
  3. Drier model & fan speed
  4. Ambient conditions

Some examples of the theoretical level of grain drier fuel cost savings are:

125°C hot air temperature, 15°C ambient, percentage saving 16% to 18% depending on drier model selected.

70°C hot air temperature, 15°C ambient, percentage saving 21% to 24% depending on drier model selected.

Maximise Your Operational Savings

Increase your theoretical operational cost savings up to 35% by combining Hot Air Recirculation with:

  1. Automatic Grain Moisture Monitoring
  2. Grain Drier Control via PLC Panel
  3. Insulation
