Combination Oven with Independent Cooking Modules

A modular oven includes a cabinet receiving separate modules with distinct cooking operations. Modules of the modular oven may provide any combination of convection cooking, steam cooking, impingement cooking, and high speed cooking. Therefore, the modules may be mixed and matched to suit the desired cooking operations. In some embodiments, improved steam cooking at lower cooking temperatures is provided by directing spraying water onto an independent heat source, controlled separately from the cavity heating element, within each cooking zone. By operating a separate heating element specifically for steam generation, there can be more accurate heat control of the cooking zones without overheating the cooking zones when steam is needed but when lower cooking temperatures (e.g., 211 degrees Fahrenheit and below) are desired.
