Impingement TUNNEL freezerS

FPS impingement tunnels have been developed for a range of cooling and freezing requirements, including pre-cooling and crust freezing for further processing as well as complete freezing.

Our impingement tunnel incorporates a hygienic pressure duct system to deliver high velocity air that quickly cools or freezes products. The proprietary air duct design ensures efficiency and maximizes yield, even with products of varying geometries.

The impingement freezers are available with multiple belt pass and lane arrangements and varying belt widths and belt types to match your production needs.

 
 

Features

  • Externally mounted fan motors

  • Proprietary duct design for quick and efficient heat transfer

  • Hygienic fully welded stainless steel construction

  • SynchroSD™ Sequential Defrost System for prolonged production runs

  • Recirculating Clean-In-Place (CIP) system

  • Slip-resistant sloped floors for effective drainage


Optimized Impingement Design

The air duct design functions as an air knife, directing high velocity jets of cold air from above and below the product throughout the tunnel. High-pressure, high-speed air breaks the insulating boundary layer of air on the product’s surface, resulting in a quick freeze with minimal moisture loss.

When it comes to delicate products, perforated plates can be used to provide gentler but equally powerful air flow for impingement freezing.

Hygiene & Ease of Cleaning

By embedding a support structure, our fully welded enclosures allow fan motors to be mounted externally. This helps limit components inside the enclosure to improve cleanability. Our flexible TIG-welded panel joints ensure smooth food-safe surfaces and can accommodate wide temperature changes.

Inside the tunnel enclosure, hollow or angle-shaped supports and unnecessary bolted structures are removed to reduce potential bacterial harborage points, further allowing for easy and safe inspection and cleaning. We also offer recirculating Clean-In-Place (CIP) systems for repeatable, full tunnel cleaning. The optional pasteurization step helps maximize freezer hygiene with minimal use of labour and energy.

Enhanced Production Efficiency

To realize high freezing rates and quality, we design our impingement tunnels with ease of maintenance at their core. For example, mounting fan motors externally protects these components from the harsh internal environment, which reduces maintenance over their extended service life and makes replacements easy.

Our SynchroSD™ Defrost System enables sequential defrosting with no impact on freezer performance or product quality. Precise airflow control ensures consistent air temperature and velocity throughout production, even when defrosting. Our impingement freezers optimize efficiency while creating savings for customers.
