Abstract: A heating cooking device includes a casing accommodating a heating furnace allowing a heating target to be located therein; a water storage tank; a hot vapor generation device connected with the water storage tank; a superheated vapor generation device heating hot vapor; a fan introducing superheated vapor into the heating furnace; and a superheated vapor discharge portion. The hot vapor generation device includes a first electric heater; and a first housing accommodating the first electric heater. A water level in the first housing matches a water level in the water storage tank. The superheated vapor generation device includes a second electric heater; and a second housing accommodating the second electric heater. At least a part of the second housing is located in an interior of the heating furnace. The hot vapor generation and the superheated vapor generation device are accommodated in the casing.

Abstract: A retort sterilization device includes a water steam generation device for generating water steam and a heating pot, connected to the water steam generation device, for accommodating retort food. The water steam generation device includes a heat exchanger for performing heat exchange between liquid flowing in a liquid path and heating vapor flowing in the vapor path. A top end of the liquid path of the heat exchanger is connected via a water steam supply pipe to a water steam ejection section located in an internal area of the heating pot. The heat exchanger is connected to a liquid container. A bottom end of the liquid path of the heat exchanger is connected to the liquid container via a communicating tube. The liquid container is coupled to the heating pot.
