IQF Tunnel Freezer Belts: Eye Link, Flat Wire or Balanced Weave?
Short answer
Eye link belts suit long tunnels where strength and airflow matter; flat wire belts give a flat, very open surface for draining and light products; balanced weave belts give closer support for small or soft pieces. Product size, open area, drive and cleaning decide.
01Which tunnels does this cover?
Buyers describe these lines in different ways: freezing tunnel, IQF freezer tunnel, tunnel blast freezer, blast freezer tunnel, impingement freezer, impingement tunnel freezer or small IQF tunnel freezer. Whatever the name, the belt is reviewed against the product, the tunnel width, length and drive, and the cleaning method.
02Compare the three

| Eye link | Long tunnels, heavier products, strong airflow | Rod and eye-link pitch, edge |
| Flat wire | Flat, very open surface; draining | Openings, strip size, edge |
| Balanced weave | Small or soft pieces needing closer support | Spiral and crimp pitch, drive |
