Tunnel Freezer

As a leading food freezer manufacturer in China, Aeroasia has a range of quality tunnel freezers, including straight tunnel, twin belt tunnel, multi-belt tunnel, and IQF multi-stage tunnel freezers.

The tunnel freezer is a continuous in-line belt freezer designed to minimize product weight loss and gently handle the product during freezing. The tunnel freezer has a simple structure, being one line from where the product enters to where it leaves. It's much longer than a spiral freezer and takes up more room, though it has the same output. The tunnel freezer is widely used in such industries processing fruit, vegetable, seafood or poultry.
