Abstract: A continuous conveyor oven process for fully cooking bone-in poultry food items is provided. A single conveyor line is provided at a constant belt speed having a first microwave oven stage and a second convection oven stage, each stage includes an infeed end and a discharge end. The bone-in poultry food item is cooked within the first microwave stage to an outlet temperature and is discharged to a convection oven, wherein the bone-in poultry food item continues to be cooked to a convection out temperature at its discharge end. The bone-in poultry food item from the microwave infeed end to the convection oven discharge end is conducted at a constant belt speed for improved throughput and food item yield with improved consistent food item quality.
