Overview

An air blast freezer uses high-velocity cold air to freeze fresh product quickly. Rooms typically operate around -35°C to -40°C (design-dependent) to form small ice crystals and protect texture.

Design notes

Slow freezing in a -20°C holding room can rupture cells and soften meat after thaw. Blast design depends on:

  • Batch volume and layout (pallets / trays / racks)
  • Inbound product temperature and target freeze time
  • Plant capacity, fan duty, and defrost cycles

When to use / expected results

Suited to pork, beef, poultry, and seafood plants that must freeze before long-term storage. When load is matched, product usually hits target temperature on schedule — outcomes depend on species and pre-blast handling.
