Driers, for grain, lumber, food and textiles, exhaust hot air constantly. Recovering that heat cuts fuel cost per ton processed.
Right configuration
- Sensible plate only: recover heat but do not return moisture to the inlet (protects product quality).
- U-type heat pipe is only a dehumidification standby, not the primary recovery.
- Corrosion-resistant plates for moist, sometimes acidic exhaust.
Result
Pre-heating inlet air with recovered heat typically cuts dryer fuel use 15% to 30%. See industrial recovery and materials.
