Abstract
Abstract A method for eviscerating pig carcasses comprising insertion of a plug into the anus of the carcass in order to avoid contamination of the carcass. Before the plug is inserted into the anus it is cooled down to a low temperature, such as below -20° C. The plug will freeze on to the area around the anus sealing the anus tightly. In this way the casing contents will not flow out during the cutting or boring-out of the rectum and further treatment of the casings. The plug comprises a sealing section 1 having a large cold capacity.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
37 words
A method for eviscerating animal carcasses, said method comprising the steps of: freezing a plug to a temperature below the point of water; inserting the plug into the anus of a carcass; and cutting around the anus.
Claim 2
Independent Claim
37 words
A method for eviscerating animal carcasses, said method comprising the steps of: freezing a plug to a temperature below the point of water; inserting the plug into the anus of a carcass; and cutting around the anus.
Claim 3
Dependent Claim
32 words
Method according to claim 1, wherein the plug is cooled down to such a temperature that, after the insertion into the anus, it will freeze on to the carcass at the anus.
Claim 4
Dependent Claim
24 words
Method according to claim 2, wherein the plug is cooled down to -20° C. or below before the insertion, especially -40° C. or below.
Claim 5
Dependent Claim
13 words
Method according to claim 1, further comprising the step of moistening the plug.
Claim 6
Dependent Claim
21 words
Method according to claim 1, further comprising the step of freezing a liquid to a predetermined shape to form the plug.
Claim 7
Dependent Claim
45 words
A plug for insertion into the anus of an animal carcass for eviscerating the carcass, said plug comprising a sealing section which defines a seal face and an elongate inserting section, said sealing section having a heat conductivity greater than that of the inserting section.
Claim 8
Dependent Claim
45 words
A plug for insertion into the anus of an animal carcass for eviscerating the carcass, said plug comprising a sealing section which defines a seal face and an elongate inserting section, said sealing section having a heat conductivity greater than that of the inserting section.
Claim 9
Dependent Claim
41 words
A plug for insertion into the anus of an animal carcass for eviscerating the carcass, said plug comprising a sealing section which defines a seal face and an elongate inserting section, a substantial portion of the plug being formed of ice.
Claim 10
Dependent Claim
41 words
A plug for insertion into the anus of an animal carcass for eviscerating the carcass, said plug comprising a sealing section which defines a seal face and an elongate inserting section, a substantial portion of the plug being formed of ice.
