Hardening Tunnel

The Dantech Hardening Tunnel is designed for re-freezing products that have been glazed.

Hardening Tunnel


The Dantech Hardening Tunnel is ideal for products that undergo glazing during the freezing process, such as shrimp. The Hardening Tunnel ensures a quick and even re-freezing of a product’s glaze layer, before entering a final equalized freeze. This creates an evenly coated frozen layer that is maintained throughout distribution and until the product is ready to eat.
