Spiral Hardner
Even Hardening, Zero Cracks
A Spiral Hardener completes the freeze cycle for dairy and cheese products, taking them from cooled or partially frozen state to fully hardened, pack-ready condition. Using a continuous vertical spiral conveyor with controlled, uniform airflow, it hardens product evenly throughout - preventing the cracking, uneven texture or surface deformation that can happen when butter and cheese harden too quickly or unevenly.
