A method of cooling a dressed carcass of a slaughtered animal halved along the backbone thereof while transferring the dressed carcass in a cooling chamber is provided, with which reduction in process yield in the cooling process due to evaporation of water from the dressed carcass is suppressed to a minimum, meat juice dripping together with water does not occur when cutting the dressed carcass, the cooling period of time is reduced, energy is saved in cooling process, initial cost is reduced, and productivity is improved. The dressed carcass is cooled while transferring in the cooling chamber in a hanged attitude along the transport route T, whereby a plurality of partitioned spaces are provided in the cooling chamber1 such that they are arranged along said transport route with a relatively small distance between them in a zone where the surface of the dressed carcass is cooled quickly and with a relatively large distance between them in a zone where surface temperature of the dressed carcass has approached the temperature of the cooling chamber and the dressed carcass is cooled slowly, and water is added to the surface of the dressed carcass while blasting cold air on to the dressed carcass in the partitioned spaces.

L'invention concerne un procédé destiné au refroidissement d'une carcasse habillée d'un animal abattu coupé en deux le long de la colonne vertébrale de l'animal, lors du transfert de la carcasse habillée dans une chambre de refroidissement. Ce procédé permet de réduire à un minimum le rendement du processus de refroidissement en raison de l'évaporation de l'eau de la carcasse habillée, d'éviter l'écoulement de jus de viande avec de l'eau lors du découpage de la carcasse habillée, de réduire le temps de refroidissement, de réduire la consommation d'énergie lors du refroidissement, de réduire les coûts de départ et d'améliorer la productivité. Ce procédé consiste à refroidir la carcasse habillée lors de son transfert dans la chambre de refroidissement suspendue le long d'un circuit d'acheminement T. La chambre de refroidissement (1) contient une pluralité d'espaces cloisonnés, disposés le long dudit circuit, séparés d'une distance relativement courte dans une zone où la surface de la carcasse habillée est refroidie rapidement et d'une distance relativement longue dans une zone où la température de surface de la carcasse habillée est proche de la température de la chambre de refroidissement, la carcasse refroidissant lentement. De l'eau est ajoutée à la surface de la carcasse habillée en même temps que de l'air froid est appliqué à la carcasse habillée dans les espaces cloisonnés.
