Air-to-Air Heat Exchangers & Heat Recovery · Since 2005

Heat Exchanger Selection for Food and Beverage Plants

Food and Beverage Duty

Food and beverage plants need recovery on process and ventilation air, but the environment is demanding: frequent washdown, cleaning chemicals, high humidity, and strict hygiene. Material and cleanability decide whether the recovery core lasts.

Material Selection

Polymer (PP) or stainless-steel cores resist the corrosive cleaning agents and moisture better than bare aluminum in these plants. Smooth, accessible surfaces and the ability to withdraw and wash the core support sanitation schedules and audit readiness.

Condition Best material
Aggressive cleaning Polymer or stainless
General duty Aluminum or coated

Recovery Targets

Exhaust from cooking, drying, and pasteurization is hot and often humid; recovering it to make-up air or process water cuts steam and heating demand. A bypass protects product profiles on hot days.

Outcome

Plants report 25 to 45 percent cuts in heating and steam energy with payback often under two years, while the hygienic, cleanable core meets audit expectations. Documented savings also support food-safety and sustainability reporting.

Sizing and Selection Checklist

Condition Material
Aggressive cleaning Polymer or stainless
High humidity Coated or polymer
General duty Aluminum or coated
Service Withdrawable, washable

Common Pitfalls

Food plants sometimes specify bare aluminum and watch it fail under washdown chemicals. Others make the core hard to remove, so sanitation slips and audit findings follow. Ignoring process-water recovery leaves the larger saving unused.

Frequently Asked Questions

Can the core be sanitized?

Yes, polymer and stainless cores withdraw and wash, supporting the cleaning schedule and audit readiness.

Is air or water recovery better?

Both help; recovering heat to process water or make-up air often cuts more steam than air-side recovery alone.

Summary

Food and beverage recovery needs hygienic, corrosion-resistant, cleanable cores to deliver savings that also pass audits.

Next Steps for Food and Beverage Plants

Begin by mapping every hot, humid, or washed-down stream, then match a material and recovery target to each before ordering.

  • Inventory heat streams and rank them by temperature and continuity of duty.
  • Shortlist polymer or stainless cores for washed-down and corrosive areas.
  • Pilot recovery on process water heating, which usually cuts the most steam.

Validating the core against the real cleaning regime protects both hygiene audit results and the energy saving.

Cost, Payback and Upkeep

Food and beverage recovery costs more where hygienic, corrosion-resistant materials are required, but the payback is fast because process heating and steam are expensive and the duty is continuous. The right material also avoids early failure and lost production.

  • Capital: polymer or stainless cores for washed-down and corrosive duty.
  • Payback: around two years where process-water recovery is used.
  • Upkeep: withdrawable, washable cores that meet sanitation schedules.

Validating the core against the real cleaning regime protects both hygiene audits and the energy saving.

Key Takeaways

Food and beverage recovery needs hygienic, corrosion-resistant cores: inventory heat streams and rank by temperature and continuity, shortlist polymer or stainless for washed-down duty, and pilot process-water recovery where it cuts the most steam.

  • Inventory and rank heat streams.
  • Use polymer or stainless for washdown.
  • Pilot process-water recovery first.

With the right hygienic, cleanable core, the recovery unit passes audits and keeps production online, which is worth as much as the energy saved. Validating the selection against the real cleaning regime protects both compliance and the continuous saving the plant depends on.
