ABSTRACT:
A pressurized injection steamer for heating food items such as pastries, rolls or the like to render them appetizing both in appearance and taste. The steamer includes a pressurized steam generating chamber below a food supporting surface. The food supporting surface includes a plurality of upstanding, hollow injector needles having one or more steam outlet holes adjacent the upper end upon which the food items to be steam heated are impaled. A generally horizontal, non-heat conducting elongated tube enters the steam chamber through one of the side walls for spraying tap water through side orifices into the steam chamber and the water falls onto a subjacent heated platen for immediate vaporization. An apertured baffle plate above the water inlet tube prevents non-vaporized liquid from entering the open bottoms of the hollow needles. The elongated tube is further insulated to prevent heating of the incoming water through the walls of the steam generating chamber. The cover plate is releasably secured to the top of the steam generating chamber by cam locking or other means. A safety interlock prevents the introduction of water into the steam chamber prior to secure locking of the cover plate.
