Convective heat transfer in a tray stack of food products during cooling: influence of air velocity and packaging.

Transfert de chaleur convectif dans des arrangements de produits alimentaires au cours du procédé de refroidissement : influence de la vitesse d'air et de l'emballage.

Author(s) : CARNIOL N., ALVAREZ G., KONDJOYAN A.

Summary

An experimental study was carried out to determine the local heat transfer coefficients in a scale model of industrial pallets. The products were simulated by circular cylinders of finite height and size 50 x 50 mm. 1800 cylinders were arranged in 10 trays, where the longitudinal and transversal dimensionless distances between the cylinders were equal to 1.1. The axial and radial non-uniformity of convective heat transfer was observed. Results of tests are presented.
