Cortex CBF 496/7 SALMON TWIN

Cortex CBF 496/7 SALMON TWIN

Features and application range

  • cutting width: 2 x 300 mm (double lane)
  • cutting speed: 24 m/min
  • double lane skinning machine optimized for skinning fresh and smoked salmon
  • 3 methods of skinning: 
    - deep skinning with sharp blade
    - thin skinning (shallow skinning) with sharp blade
    - pulling-off the skin with blunt blade (silver skinning)
Thin skinning with sharp blade and NOCK Active Skin Gripper®

Standard equipment

  • suitable for double lane feeding, therefore 2 separate blade holders, 2 tooth rollers, 2 pressure units
  • tooth rollers (AISI 316L) with grooves and scraper comb (CF technology)
  • NOCK ACTIVE SKIN GRIPPER® ASG for thin skinning with sharp blade, no remaining skin on the fish tail 
  • blade gap independently and infinitely adjustable on the right and left side
  • spring suspended blade holders for perfect skinning results
  • pressure units with pneumatic release; infinitely height adjustable
  • special hard pressure roller for salmon, made of polyamide with very long lifetime and more pressure in the middle of the fillet (less pressure at the sides of the fillets = less loss when deep skinning)
  • water cleaning unit for steady continuous operation when processing fresh fillets
  • infeed and output conveyor; can be taken out of the machine within seconds without any tools
  • NOCK POWER PLATES® for a machine construction which is easy to clean, for outstanding robustness and service friendliness
  • NOCK EASY-FLOW® safety cover with pneumatic springs
  • lockable castors
  • stainless steel
  • stainless steel bearings


  • transfer plates on which fillets pass  through without being skinned

Tip: With the NOCK Cortex CBF 496/7 SALMON TWIN you achieve deeper skinning in the area of the dark side muscle due to the standard hard pressure roller for salmon. This effects more pressure in the middle of the fillet and therefore a deeper skinning. The sides of the fillets are skinned less deep.
