The SMO Spiral Tunnel, a product Made in Clauger, allows for either continuous or in-line cooling or deep-freezing of products. This interest lies in its automation of processes, optimization of energy usage, and increase in productivity.

The SMO Spiral Tunnel is a spiral freezer with conveyor belt technology, making it ideal for continuous and integrated in-line applications, such as:

  • Rapid cooling
  • Deep freezing
  • Drying

This system provides a temperature range of -40°C to +40°C, enabling product freezing, cooling, or drying. SMO tunnels integrate easily into your plant’s existing process lines and can be used to automate production, cut energy costs, and increase productivity:

  • Less material handling,
  • Product quality improved.
  • Increase capacity of operating cycles.
  • Optimize energy use per pound or unit of product.

The SMO tunnel is suitable for packaged products or IQF (individually quick frozen), whether raw, cooked, exposed, or packaged. This tunnel is ideal for bread, pastries, processed products such as nuggets, cordon bleu, pizzas, fruit compote, stirred yogurts, and dairy desserts.


The spiral band cooler-freezer is a solution that can be adapted to product requirements, process needs, and location constraints.

Clauger offers a “Compact” series of the SMO tunnel. Entirely manufactured, assembled, and tested in our workshops. The tunnel is a single-piece, plug-and-play design. The tunnel can be integrated into the production line and connected to the refrigeration system in under two days.
