A cold room holds product at a set temperature. A blast freezer (or blast chiller) rapidly pulls heat out of product to pass through the danger zone quickly and lock in quality.
Quick comparison
- Cold room — storage for chilled or frozen stock over hours/days/weeks.
- Blast freezer — process equipment for rapid freezing cycles before storage.
Many sites need both: blast to freeze, then transfer to a walk-in freezer or chill room. See our blast freezer and cold rooms pages.
