PROBLEM TO BE SOLVED: To provide a cooking device capable of producing high quality rice cake and an operation method of the cooking device.SOLUTION: A cooking device includes a cooking container 1 accommodating rice cake material including glutinous rice and water, mixing means M for mixing the rice cake material in the cooking container 1, a casing 3 in which a heating chamber 2 accommodating the cooking container 1 is formed, heating means 6 for heating the inside of the heating chamber 2, and control means 8 which controls operation of the heating means 6 and the mixing means M to perform a gelatinization step for heating and gelatinizing the rice cake material in the cooking container 1 and a mixing step for mixing the rice cake material gelatinized in the gelatinization step. The device also includes gelatinization termination determination means J for determining the termination of gelatinization of the rice cake material in the cooking container 1. The control means 8 terminates the gelatinization step and starts the mixing step on the basis that the gelatinization termination determination means J determines termination of gelatinization.COPYRIGHT: (C)2015,JPO&INPIT【課題】高品質の餅を作ることが可能な調理器及び調理器の運転方法を提供する。【解決手段】もち米及び水を含む製餅材料を収容する調理容器1と、調理容器1内の製餅材料を混練する混練手段Mと、内部に加熱室2を形成し且つ当該加熱室2に調理容器1を収容するケーシング3と、加熱室2内を加熱する加熱手段6と、加熱手段6及び混練手段M夫々の作動を制御して、調理容器1内の製餅材料を加熱して糊化させる糊化工程と、糊化工程で糊化された製餅材料を混練する混練工程とを実行する制御手段8とを備えた調理器であって、調理容器1内の製餅材料の糊化終了を判断する糊化終了判断手段Jが設けられ、制御手段8が、糊化終了判断手段Jにより糊化終了が判断されたことに基づいて、糊化工程を終了して混練工程を開始するように構成されている。【選択図】図2
