Abstract

PURPOSE:To efficiently perform heat processing in a rice cooking heating process by circulating steam which has passed rice once, and by setting a steam circulating means for keeping uniform the steam pressure of the internal section of a device. CONSTITUTION:In a steam circulating device 33, steam jetted from a steam feeding section 25 and flowing to a steam exhaust port 35 through rice 10 is circulated by a circulating pipe 36, and is fed to the lower section of a rice cooker main-body 12. Besides, a pressure regulating valve 34 is set, and till the steam pressure of the interior of the rice cooker main-body 12 comes to fixed pressure or more, the valve 34 is contrived not to be worked, and the steam pressure of the interior of the rice cooker main-body 12 is kept uniform during rice cooking heating. At the initial step of a rice cooking heating process, the pressure regulating valve 34 working by the pressure of the interior of the rice cooker main-body 12 is closed, and so high temperature steam jetted from the steam feeding section 25 passes the rice 10, and after that, the steam is fed to the steam circulating device 33 from a steam outlet 35, and is fed again to the interior of the rice cooker main-body 12 from the lower section of the main body 12, and the steam pressure of the interior of the rice cooker main-body 12 under the rice cooking heating process is heightened, and heat disposal under the rice cooking heating process is efficiently contrived.
