Fish skinning machines

Cut down costs by first-class technology

Cortex CBF 496 SALMON

Cortex CBF 496 SALMON

Features and application range

  • cutting width: 430 mm
  • cutting speed: 24 m/min
  • automatic skinning machine with NOCK ACTIVE SKIN GRIPPER® ASG 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)

Standard equipment

  • 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 infinitely adjustable
  • spring suspended blade holder for perfect skinning results
  • pressure unit 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 spring
  • lockable castors
  • stainless steel
  • stainless steel bearings


  • inflated pressure balloon
  • discharge conveyor for removed skin
  • curved blade holder for further minimization of the dark side muscle when deep skinning
  • additional possibility of positioning of output conveyor for easy bringing together skin and fillet
  • double lane model (Cortex CBF 496/7 SALMON TWIN)

Tip: With the NOCK Cortex CBF 496 SALMON 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.
