Food Processing Heat Recovery: Capturing Process and Exhaust Heat

Table des matières

Food plants bake, cook, pasteurize, and chill around the clock. Both the process air and the building exhaust carry large amounts of recoverable energy - often with moisture, grease, or particulates that demand a cleanable, robust exchanger.

  • Enthalpic plate or rotary wheels recover both heat and moisture from humid exhaust (ovens, cookers, wash areas).
  • Sensible plate units suit dry, particle-heavy streams where simplicity and wash-down matter.
  • Run-around coils link distant process exhaust to incoming make-up air.

Preheat incoming fresh air in winter, pre-heat process water, or feed space heating. In cold climates, watch protection contre le gel on the exhaust side.

Choose cores rated for frequent wash-down (stainless or coated aluminum) and plan a cleaning rhythm using our cleaning & maintenance guide. Track effectiveness and pressure drop to catch fouling early.

With continuous thermal loads, food plants often recover capital in 2-4 years. Validate with a payback calculation.
