Abstract

The present invention relates to a device and a method for detaching a fibrous casing from the surface of a cured processed meat product, preferably a sausage, especially when the outer surface of the fibrous casing has been provided with a substantially inextensible net with a view to form protuberances on the surface of the processed meat mixture. The device is used for blowing compressed air between the fibrous casing and the surface of the cured processed meat mixture, so that the fibrous casing is detached from the surface of the processed meat mixture and skin removal is facilitated.

Claims

1. A device for detaching a fibrous casing from the surface of a cured processed meat product, characterised in comprising a blowpipe (1), which is adapted for blowing compressed air between the fibrous casing (5) and the surface of the processed meat product, inside a sealing ring (3), through an opening formed as the fibrous casing is drying, and means (4) for locking the fibrous casing (5) on the blowpipe (1) so as to steer compressed aid into said opening.

2. A device as defined in claim 1, characterised in that the outer diameter of the nozzle of the blowpipe (1) is calibre-specific so as to be accommodated in the tail (2) remaining behind the sealing ring as the processed meat product is sealed within the fibrous casing (5).

3. A device as defined in claim 1 or 2, characterised in that the nozzle of the blowpipe (1) has an inner diameter of 2 mm.

4. A device as defined in any of claims 1-3, characterised in that the means (4) for locking the fibrous casing (5) on the blowpipe (1) are steplessly adjustable jaws, which press the fibrous casing (5) against the blowpipe (1).

5. A method for detaching a fibrous casing from the surface of a cured processed meat product, characterised in the use of a device as defined in claim 1.

6. A method as defined in claim 5, characterised in that the outer surface of the fibrous casing is coated with a substantially inextensible net.

7. A method as defined in claim 5 or 6, characterised in that the fibrous casing (5) is locked on the blowpipe (1) by gripping the tail (2) of the fibrous casing remaining behind the sealing ring (3) as the processed meat mixture is being sealed into the fibrous casing.

8. A method as defined in any of claims 5-7, characterised in that the blowpipe (1) is used for blowing compressed air at a flow rate and under a pressure such that compressed air is steered between the fibrous casing and the surface of the processed meat product, thus detaching the fibrous casing from the surface of the sausage mixture.

9. A method as defined in any of claims 5-8, characterised in that the blowpipe (1) is used to blow compressed air under a pressure less than 1 bar.

10. A method for detaching a net-coated fibrous casing from the surface of a cured processed meat product, which has been shaped by means of said net-coated fibrous casing and comprises protuberances on its surface, characterised in that compressed air is blown between the fibrous casing and the surface of the processed meat product.
