Cortex CBF 496

Cortex CBF 496/7 Salmon TWIN

Automatic fish skinner with CF technology and application for Salmon skinning

Features and application range

cutting width:

2 x 300 mm (double lane)

cutting speed:

24 m/min


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)
  • double lane skinning machine optimized for skinning fresh and smoked salmon

Standard equipment

  • suitable for double lane feeding, therefore 2 separate blade holders, 2 tooth roller, 2 pressure units
  • tooth roller (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 conveyor and discharge 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 spring
  • 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 ofthe fillets are skinned less deep.
