Freshline® DM Tunnel Freezer

Greater flexibility with 2 machines in 1, IQF and non-IQF

Are you looking to produce both Individually Quick Frozen (IQF) and standard, non-IQF frozen products with the same machine? The Freshline® DM Tunnel Freezer was developed for you.
​Our Freshline® Dual-Mode (DM) Tunnel Freezer allows you to instantly switch from the IQF freezing mode to the standard non-IQF freezing mode depending on your production needs. When you activate the IQF mode, the belt immediately starts to vibrate for an excellent individual quick freeze resulting in a free flowing frozen product. As soon as you switch it off, the belt stops vibrating and you can start freezing regular products.

Freshline DM Case Study: Amural Productions, France

At the exit of the tunnel the sliced products are perfectly IQF. This allowed us to remove the upstream sorting station and automate the process.

How can the Freshline DM freezer generate both IQF and non IQF products?

The design of Air Products’ Freshline DM tunnel freezer has flexibility in mind. The belt appears to be a regular flat belt but looks can be deceiving.  It contains features that allow it to vibrate when you activate the IQF mode.
