ABSTRACT:
A steam processor for preparing or warming food items. The processor includes a cooking chamber having a steam inlet and outlet, and an adjacent steam generator for supplying steam to the chamber. The steam generator includes a water level control system for maintaining a water level within the generator within predetermined limits and an immersion heater for vaporizing the water. A steam control is provided that regulates the heater to control the rate at which steam is produced and flows into the cooking chamber. The processor includes an automatic drain feature which discharges any water within the steam generator whenever power to the processor is terminated. A steam condenser that condenses steam exhausted by the chamber is disposed near the outlet of the cooking chamber. The condenser precipitates a sub-atmospheric pressure at the outlet which serves to purge air from the chamber and enhance the flow of steam into the chamber. The water supply for the steam generator flows through a preconditioner which pretreats the water to minimize the formation of deposits in the steam generator and associated plumbing.
