Abstract: A steaming oven having a clad plate bottom. The stainless steel clad material constitutes the bottom of the boiling water reservoir in the oven chamber. The stainless steel clad material is composed of a thin layer of stainless material clad to a thicker plate of base, heat conducting metal like steel, copper or aluminum.

Abstract: A steaming oven having a collector plate disposed in an oven chamber. A collector plate is disposed above a boiling water reservoir in the oven chamber. The collector plate has a drain tube inserted into an overfill tube. Waste material from the steam and food droppings is conveyed from the oven chamber via the drain tube and the overfill tube. A barrier shields one or more water level probes or sensors from water turbulence, thereby providing reliable water level sensing by the water level probes or sensors.
