  • Apparatus for dividing deep-frozen foodstuffs, with recovery of foodstuffs detached during said division
    Patent number: 5286230
    Abstract: A device for cutting up deep-frozen foodstuffs, in particular fish, has a plurality of saw bands (6) of a band saw arranged side by side at a distance apart, which cut the right parallelepipedal bodies (2, 3) into a plurality of smaller right parallelepipedal units. The fragments produced during cutting are extracted by a current of blast air, which flows around each saw band, onto a pressure roller (9) arranged on top of the right parallelepipedal bodies (2, 3) viewed in the direction of transport before the saw bands (6). The pressure roller (9) spreads the fragments onto the right parallelepipedal bodies (2, 3). After being cut by the saw bands (6), the smaller units undergo no further changes.
