CRYOLINE XF Spiral Freezer

The CRYOLINE® XF delivers twice the heat transfer rate of standard cryogenic spiral freezers whilst rivalling the throughput capabilities of its mechanical alternatives; all with a 50% smaller footprint.

CRYOLINE XF Spiral Freezer

With dehydration levels 80% lower than those achieved with mechanical spiral freezing, the CRYOLINE XF is the perfect choice for a wide range of high-quality food products with a high moisture content such as red meat and poultry, ready meals, seafood and bakery products.

Freezing with cryogens provides a very low operating (freezing) temperature. Combined with the CRYOLINE XF’s innovative freezing technology, this results in a rapid freezing action that is 50% faster than other cryogenic spiral freezers. This rapid freeze preserves the quality and shape of the product and delivers increased product yield.

Process overview

The CRYOLINE XF uses an advanced cross-flow technology which substantially reduces freezing time and improves cryogen efficiency whilst reducing overall freezer size. It provides twice the heat transfer rate of conventional spiral freezers by covering nearly 100 % of the belt freezing surface area with a high-velocity gas flow. Steady-state losses are minimized due to the reduced overall size which means that there is 50 % less stainless steel to be cooled down.

Typical products

The CRYOLINE XF is the perfect choice for a wide range of high-quality food products:

  • red meat and poultry
  • ready meals
  • seafood
  • bakery products
  • high temperature and high moisture products, e.g. cooked poultry.

Features and benefits

  • Touch screen control, allowing storage/recall of recipe parameters for consistent operation.
  • Fault diagnostics, should an error occur the touch screen provides specific information about the cause of the fault.
  • Designed in accordance with European safety standards, stamped CE and Declaration of Conformity issued.
  • Simplified design including sloped, solid surfaces and rounded corners maximises productivity by reducing cleaning and maintenance downtime. An optional feature includes a CIP (“clean-in-place”) system.
  • Quick installation and commissioning process with minimal disruption to production schedules.
