Abstract

A method for the continuous treatment of poultry carcasses. The poultry carcasses are successively singed, cooled, deboned, minced, shaped and packaged. Prior to singeing, the carcasses are injected with carbon dioxide snow to prevent the development of germs during singeing. The mincing, shaping and packaging steps are carried out in an enclosure in which carbon dioxide snow is introduced so that the temperature is maintained at about 0° to -4° C.

Claims

1. A process for continuous treatment of poultry carcasses for the manufacture of minced meat, comprising the steps of:

(i) injecting carbon dioxide snow inside the warm carcasses coming from the abattoir, after evisceration thereof;

(ii) immediately performing a singeing operation on the carcasses inside which carbon dioxide snow has been injected;

(iii) cooling the singed carcasses;

(iv) de-boning the singed and cooled carcasses;

(v) mincing the de-boned carcasses;

(vi) shaping the minced meat and packaging it into containers,

(vii) the mincing, shaping and packaging steps being carried out in a substantially thermally insulated and gas-tight enclosure within which the temperature is maintained at about 0°

to -4°

C. by introducing controlled quantities of carbon dioxide snow inside the enclosure while evacuating controlled quantities of the air and other gases contained within the enclosure.

2. A process as claimed in claim 1, wherein controlled quantities of an oxygen containing gas mixture are further introduced in the said enclosure in a region thereof where the said packaging step is carried out.

3. A process as claimed in claim 1, wherein the i, ii and iii are carried out inside a ventilated enclosure.
