Characterization of airflow inside a refrigerated trailer loaded with carcasses

Caractérisation des écoulements d'air dans une semie remorque chargée de carcasses de viande

Résumé

After slaughtering, pork carcasses should be cooled down as fast as possible to reach a core temperature of 7°C (current requirement in European regulation) before transport in order to inhibit the growth of spoilage and pathogen microorganisms. To reach this temperature, carcasses are usually loaded into chiller rooms (15-20 hours) where the rate of cooling is controlled. To reduce the logistic time from slaughter house to cutting plant, a solution is proposed by loading the product into a trailer at core temperatures higher than 7°C. However, we have to assess that such a practice will not lead to a sanitary risk when applied to real scenario. In order to answer this issue, the first step will be to study the airflow characteristics within a trailer filled with pre-chilled pork carcasses. The objective of this study is to investigate experimentally the air velocity distribution in a reduced scale trailer filled with reduced scale carcass models under isothermal conditions. The 215 carcass models were made of polyurethane foam using a mold obtained by 3D printing based on X-ray scanner of a real carcass. The Reynold number in the experimental device is the same as in a real trailer (Re ~1.3
