The GS 10-2 belt cutting machine with the two wing knife is used to cut the fish. The raw salmon fillet pieces are placed lengthwise on the belt of the GS 10-2. This ensures that the salmon fillets are transported into the machine in the correct orientation. Thanks to the downholder, the salmon fillets remain in their position at the cutting edge and can thus be cut into strips of similar size, e.g. 10mm long, with a clean cut. This prevents the formation of excessive fines. The salmon strips can then be used e.g. as ingredients for sushi.
