An air impingement oven having a conveyor belt assembly (30) for moving food through a heat treatment passage. The air impingement oven has a fan, a supply duct (42), a plenum (44) and a number of jet fingers (46) being disposed above the conveyor belt assembly (30). The jet fingers (46) have a base portion having a number of orifices for directing the impingement air onto the food. The orifices have an improved configuration. The improved configuration intensifies the airflow on the food to penetrate heat into the food surface thereby improving heat transfer. The improved configuration reduces a cooking time of the food in the air impingement oven.
L'invention concerne un four à air équipé d'un ensemble courroie de transport (30) pour le déplacement de la nourriture par un passage de traitement thermique. Le four comporte une soufflante, une conduite d'alimentation (42), un plenum (44) et plusieurs doigts de pulvérisation (46) au-dessus de l'ensemble courroie (30). Les doigts (46) ont une partie de base ayant plusieurs orifices dirigeant l'air sur la nourriture. Les orifices ont une configuration améliorée qui intensifie le flux d'air sur la nourriture, faisant pénétrer la chaleur sous la surface de la nourriture et améliorant ainsi le transfert thermique. La configuration améliorée réduit le temps de cuisson de la nourriture dans ledit four.
