Three methods of skinning
The NOCK fish skinning machines provide 3 methods of skinning:
1. Thin skinning with sharp blade
When thin skinning (shallow skinning) with sharp blade, the blade gap is closed so much that nearly no meat of the fish remains on the skin. The blade gap can be adjusted infinitely and sensitively with the lever outside the machine, also during operation.
Spring suspension of the blade holder

The spring suspension of the blade holder results in perfect adjustment to the various thick skins. This suspension is located in the machine casing out of the processing area.
Robust precision part: NOCK blade holder

Tip: Especially when thin skinning it is important that the geometry of the blade, the blade holder and the tooth roller are balanced best possible. This is guaranteed only with original NOCK TOP H blades. The use of other blades (despite nominal equal measurements) can clearly result in more loss, worse skinning results and shorter lifetime.
For thin skinning of salmon fillets, the Active Skin Gripper® of the NOCK Cortex CBF 495 SALMON achieves record values at the yield without remaining skin on the fish tail.
2. Deep skinning with sharp blade
When deep skinning with sharp blade, the blade holder can be opened so that it is possible to take off almost the whole layer of fat. The blade gap can be adjusted infinitely and sensitively with the thickness adjusting lever, also during operation.
So with some fish species it is possible to increase the quality of the fillets and the price to be gained like this, so that the higher loss of weight can be balanced above.
When skinning salmon, the NOCK Cortex CBF 495 SALMON achieves a more deep skinning in the area of the dark side muscle due to the hard pressure roller made of polyamide which is standard in the machines. This effects a bigger pressure in the middle of the fillet and therefore a deeper skinning. The sides of the fillet are skinned less deep and so the yield is improved despite comparatively high skinning at the dark side muscle. This effect can be assisted by the curved blade holder which is optionally available.

3. Pulling-off the skin with blunt blade
When pulling-off, the skin is divided from the fillet with the blunt edge of the blade, so that the silver mirror stays on the fillet („silver skinning“). Here the blade is put into the blade holder with the blunt edge outside and the blade holder is completely closed („tight“). So, compared to the thin skinning with sharp blade, the yield can be further increased and the desired performance of the fillets with the silver mirror is achieved for some species of fish.
