Potato Freezing Tunnel – Superior Quality & Professional Preservation

In the ready-food industry, fast and professional freezing is a critical step to ensure the final product’s quality and to preserve its taste and texture before selling or frying.
If your next stage after blanching and drying is freezing, then the Smartpack Potato Freezing Tunnel is the ideal solution to achieve:

✔ Uniform freezing for all potato pieces
✔ Preserved texture and structure after blanching
✔ Perfect preparation for packaging or direct sale

With smooth integration between production stages such as the Smartpack Frozen Semi-Fried Potato Blanching Machine and the Smartpack Potato Drying Machine, you obtain a complete, efficient potato production line that meets global quality standards.

The Smartpack Freezing Tunnel is used for continuous professional freezing of semi-fried or ready-to-freeze potatoes before packaging or storage.
The tunnel works by moving the product through a refrigerated chamber with controlled speed and low temperatures, reducing the formation of large ice crystals inside the potato tissue.

This system can be easily integrated with other processing units such as the Smartpack Potato Drying Machine and the Smartpack Front Conveyor Belt for full production continuity from preparation to final packing.
