Jackstone Crust Froster

The Perfect Solution for Delicate, Sticky & Shape-Sensitive Products

The Jackstone Crust Froster is designed for processors who need to gently freeze the underside of delicate, wet, or sticky products without compromising shape, texture, or yield. It’s the missing link between your production line and finish freezer — ensuring products can safely move into spiral freezers or other systems without sticking, deforming, or losing moisture.

Why Choose the Jackstone Crust Froster?

Protect Product Integrity

The Jackstone Crust Froster quickly creates a thin frozen crust on the underside of your products — preventing sticking, deformation, belt marks, or drip loss. It locks in the shape and appearance of your product, so it looks just as good after freezing as it did fresh off the line.

Faster, Cleaner Freezing

A contact freezing plate with a thin layer of hygienic, food-grade plastic film ensures your product doesn’t stick. The film provides full heat transfer while keeping the freezer surface clean. Used film is automatically rolled up and disposed of, guaranteeing hygiene at every step.

Hygiene & Yield Benefits

By sealing moisture to the underside of the product, drip losses are nearly eliminated — both during freezing and when thawed. No dripping inside your spiral freezer means better hygiene, less cleaning, and more uptime.

Operational Efficiency

  • Rapid Freezing: Freezes the underside of your product to 1 mm depth in just one minute.
  • Higher Throughput: Reduces dwell time in finish freezers, increasing line capacity.
  • Self-Defrosting: Frost and ice never accumulate on the freezer itself.
  • Cost-Effective: Disposable film has minimal cost per unit processed.

Flexible & Scalable

The Jackstone Crust Froster is available in various sizes and capacities, from 50 kg/hr to 2,500 kg/hr. Optional top airblast sections are available to crust-freeze the entire product surface, allowing stacking without sticking.
