Blast Chillers
Blast chillers rapidly cool freshly processed poultry carcasses from ~35 °C to a core temperature of ≤4 °C within regulatory time limits (typically 4 hours for retail-grade fresh).

Role within the project
Chilling time directly affects shelf-life and food-safety compliance. Under-sized chillers force line slow-downs; over-sized chillers waste CAPEX and energy.
Typical applications
- Air-blast tunnel chillers on fresh-chicken lines
- Immersion chillers (regulated jurisdictions permit)
- Batch chill rooms for further-processed products
Selection criteria
- Chilling time at target core temperature
- Air-blast vs immersion regulatory acceptance in your market
- Refrigerant compliance (F-gas, natural refrigerants)
- Energy per bird chilled
Engineering considerations
- Tunnel length and air velocity sized for target time
- Air-blast temperature typically -3 to +1 °C
- Immersion chill water at 0–4 °C with counter-flow
- Drainage and sanitation between shifts
Commercial considerations
- Per-bird-per-hour CAPEX comparison
- Energy per bird chilled — measurable OPEX
- Refrigerant refill and service cost
Procurement considerations
- Site acceptance test measuring core temperature vs time
- Refrigerant compliance in contract
- Standby capacity for peak-hour production
- Sanitation cycle time between shifts
Common mistakes
- Air-blast in a market that regulates chill weight-pickup (immersion) — non-compliant
- Undersized capacity vs peak-hour line output
- Ignoring energy per bird — OPEX dominates over 5 years
- F-gas non-compliance in EU / regulated markets
Ask suppliers
Ask for measured chilling time to +4 °C core at your bird size at peak-hour line output, with refrigerant compliance certificate.

Frequently asked
Air-blast or immersion?
EU regulations restrict water-uptake in immersion. US allows immersion with declared water-uptake. Middle East and Asia are mixed. Verify against your export-market regulation.
What core temperature is required?
Retail-grade fresh poultry typically requires core ≤ 4 °C within 4 hours of slaughter. Confirm your target market's exact rule.
