An automatic deliming process for a steam oven cooker is described. The process initiates a deliming procedure after a predetermined time of normal operation, which period of time is determined by the hardness of the water in the local area. Upon the expiration of this period of time a microprocessor signals an operator to shut down normal operation of the oven, and initiate the deliming process. The microprocessor then activates a peristaltic pump which injects a predetermined quantity of deliming liquid from an external reservoir into the generator. After the deliming time has passed and the generator contents have cooled to 140&deg; F. the microprocessor automatically activates a drain pump to drain the deliming solution from the generator. Subsequently the microprocessor activates a fill-solenoid opening and inlet from a reservoir of rinse water into the generator to rinse the same. The microprocessor then again opens the drain to drain the rinse water, and normal operation is resumed.

An improvement for a combination steamer and convection oven is described. The improvement includes double access doors in the front of the oven for controlling access to the cooking cavity within. The doors are cam actuated between a closed position, a first open position wherein the doors are cracked to release hot gases from within the cavity and a second open position wherein the doors are fully open. The admission of steam to the cavity is controlled by a positive displacement flapper valve and one or a pair of the ovens can be used, and if a pair is used a single steamer provides steam for either or both cooking cavities.

A control system for steam production in a oven combination is described. The control is adapted for use with a single source of steam and a plurality of oven cavities wherein cooking is achieved by a combination of convection oven and steam heat or by steam alone. The control system activates steam production in response to a temperature requirement for a particular oven and opens a valve permitting the inflow of steam into that oven alone. The control system can also be used to admit steam simultaneously to all oven cavities if required.
