Solutions · Blast Freezers & Pre-cooling
Freeze it fast. Keep the quality. Spend less doing it.
Blast freezers, blast chillers and pre-cooling rooms designed around your product and your hourly throughput, so every batch is brought down to temperature quickly without wasting power.
See Freezer Types
Overview
Speed is what protects frozen quality.
The faster food passes through its freezing range, the smaller the ice crystals that form, which means less cell damage, less drip on thawing and better texture and taste. A blast freezer achieves this with very cold air moving at high speed across the product. A blast chiller or pre-cooling room does the same job for chilled products, removing heat quickly before storage or transport.
Because a blast freezer is one of the most power-hungry machines in a cold chain, design matters. We size the refrigeration, airflow and defrost cycle to your actual batch size and cycle time. The result is faster, more even freezing at a lower cost per kilogram.
Where the savings come from
Why Weather Makers blast freezer costs less to own.
Lower Energy
Evaporator size, air velocity and compressor capacity are matched to your throughput, and defrost is timed to need rather than to a fixed schedule, so the plant does not waste power between batches.
Lower Losses
Fast, even freezing reduces weight loss and drip loss, and avoids partly frozen product at the centre of a batch.
Lower Maintenance
Defrost systems, fans and controls designed for hard daily duty, with monitoring that flags icing or a failing component before it stops production.[CONFIRM]
Lower Lifecycle Cost
Your estimate compares build cost against running cost per batch, so you can judge payback over the years, not only the quote.
What goes into it
Five parts, each chosen for your product.

Questions
Common questions about blast freezers.
What is the difference between a blast freezer and a normal freezer room?
A storage freezer room holds product that is already frozen. A blast freezer pulls heat out of fresh or chilled product quickly, so it needs far more refrigeration capacity and airflow for its size.
How do I size a blast freezer?
Size depends on how much you freeze per batch, the starting and target temperatures and how long each cycle can take. Share your product and throughput and we calculate it for you. [CONFIRM: size guidance]
Can a blast chiller and blast freezer be combined?
Some products need both. We can design a flexible unit or separate rooms. [CONFIRM]
How long does installation take?
[CONFIRM: typical timeline for a standard blast freezerand for a larger line.]
Can you upgrade an existing freezer?
Yes. See our Retrofits and Upgrades solution, which compares upgrading against building new.
