Ice Cream Hardening Tunnel
Blast hardening tunnels that rapidly freeze packed ice cream to core — supplied and integrated by ATMAN.
Get a QuoteFast to the Core
The hardening tunnel blast-freezes filled ice cream to its core quickly, locking in fine texture before cold storage. ATMAN supplies and integrates spiral and straight-through tunnels sized to your line speed.
Blast-freeze to core
Low-temperature forced-air freezing in a spiral or straight-through tunnel drops product core temperature fast — preserving fine crystals and eating quality before dispatch to cold storage.
Key Configurations
Spiral Hardening Tunnel
Compact high-capacity spiral for continuous lines.
Straight-Through Tunnel
Linear tunnel for simpler layouts and formats.
Low-Temperature Coils
Deep sub-zero air for rapid core freezing.
Line-Speed Matched
Dwell time set to your filler output.

Frequently Asked Questions
What does a hardening tunnel do?
It blast-freezes packed ice cream to its core quickly, locking in fine texture before cold storage.
Spiral or straight-through?
Spiral packs high capacity into a small footprint; straight-through suits simpler layouts. We size dwell time to your line speed.
Does it integrate with the filler?
Yes. Tunnel throughput is matched to the filler output and cold-storage handoff.
