Blast freezing and chilling equipment
Batch and continuous blast freezers, spiral IQF tunnels and plate freezers for meat, seafood, bakery, ready meals and industrial food processing lines.
ColdMatch facilitates sourcing and RFQs; it does not manufacture, sell, import or export the listed products and is not a regulatory authority. Suppliers are responsible for their products meeting the requirements of the origin and destination countries; buyers for import permissions, local rules and due diligence. Requirements vary by product and country, and the team checks requests before any supplier contact. Regulation and restricted items
Blast freezing system types we can source
General descriptions to help you define your request. Specifications, prices and lead times come only from suppliers’ written offers.
Spiral or tunnel IQF freezer
Continuous freezer that moves product on a belt through cold air so pieces freeze individually, used inside processing lines.
- Packaged unit
- Blast freezing / chilling
Plate freezer
Freezer that presses packed or block product between refrigerated plates, common for seafood, meat blocks and packed goods.
- Packaged unit
- Blast freezing / chilling
Blast chiller
Equipment that rapidly cools cooked or fresh product to chilled temperature, used in food production and catering.
- Packaged unit
- Blast freezing / chilling
- Chilled storage
What to decide before you request quotes
- Product, entry and target core temperature, and the hourly or batch quantity.
- Batch versus continuous freezing and the packaging the product enters in.
- Hygiene and cleaning requirements for the processing area.
- Connection to an existing refrigeration plant or a dedicated unit.
Compare blast freezing options
Blast chiller vs blast freezer
Does the product need to be chilled quickly, or frozen through to the core?
| Aspect | Blast chiller | Batch blast freezer |
|---|---|---|
| Purpose | Brings cooked or fresh product down to chilled temperature quickly. | Freezes product through to a frozen core temperature. |
| What happens next | Product goes to chilled storage or dispatch. | Product goes to frozen storage; a storage freezer room is not designed to do the freezing. |
| Typical users | Kitchens, catering, ready-meal and bakery production. | Meat, fish, bakery and food processors freezing in batches. |
| Key RFQ inputs | Product, batch size, entry and target temperature, cooling time. | Product, packaging, batch weight, entry and target core temperature, freezing time. |
Rule of thumb: Some units offer both modes; ask suppliers to state performance separately for chilling and freezing, on your product and packaging.
Batch blast vs spiral/tunnel vs plate freezer
How does your product arrive — in batches, on a line, or in flat packs?
| Aspect | Batch blast freezer | Spiral or tunnel IQF | Plate freezer |
|---|---|---|---|
| Product flow | Batches on trolleys or pallets. | Continuous flow on a belt from the line. | Flat packs or blocks between plates. |
| Suits | Variable or seasonal volumes. | Steady line production; individually frozen pieces. | Seafood, meat blocks and packed goods of even thickness. |
| Watch out for | Packaging and stacking that restrict air flow. | Under-use if production is irregular; floor space and hygiene design. | Irregular shapes that do not contact the plates. |
Rule of thumb: Match the freezer to how product reaches it, then ask suppliers to state freezing times for your product and packaging.
