Freezer Tunnels

Should you require a more flexible bespoke solution than bulk blast freezing or chilling, the Dawsonrentals Tunnel offers IQF (Individual Quick Frozen) product in one fast, automated and cost-effective package.

The Tunnel has the capability to core freeze, crust freeze or refreeze, and also to cool or chill heated product. The variable speed and three-belt system allows complete flexibility to run denser product through all three belts to ensure core freezing or a quick single belt run to crust freeze.

When compared with other IQF tunnel systems, the tunnel offers exceptional value with typical freezing costs being 50% less than a cryogenic system using nitrogen.

Technical details
The Tunnel is connected through pipe work to a remotely-sited refrigeration plant which can be situated up to 50 metres away. Electrical requirements, to run the package of tunnel and refrigeration plant, fall between 200 and 400 amps. Other standard and optional technical features include:

- Optional refrigeration package to suit product
  throughput and application.
- Choice of belt specification and width to accommodate
  a wide range of product sizes.
- Fast and convenient hot water cleaning regime
  and defrost system.
- Flexible drainage options.
- Design allows for fast and efficient maintenance
  checks and replacement parts.
- Clear and concise multi-functional control panel.
- Belts can accept product up to 100mm in height.

Typical application/benefits
The tunnel is designed to freeze or chill individual or portioned product. Typical examples would be:

- Fish fillets.
- Chicken portions (i.e. wings, drumsticks and breast fillets).
- Red meat, pork, lamb (minced or portioned).
- Shellfish (prawns, langoustine, crab, scallops etc).
- Savouries.

Individually freezing or chilling your product can offer several operational and cost benefits. The product retains its pre-frozen shape and condition making it aesthetically more appealing leading to wider options in terms of packaging, end retailers and ultimately higher sale value. In addition should you be tempering (defrosting) your product at a later stage, this function can be done quicker and more cost-effectively as you need only defrost what you require which cannot be done with bulk frozen product.
