To prevent the foreign matter generated by washing from remaining in a tank by rotating an annular rail fixed with a vessel in an upward open state to turn the vessel in the upward open state downward and mounting nozzles for internal washing which wash the inside of the vessel by injecting washing water therein at this annular rail.
The annular frame 64 as the annular rail having a horizontal width to allow the sufficient housing of the cooking vessel C is internally arranged with a roller conveyor 65 and proximity switches like a turn table. The annular frame 64 is provided with two pairs of locking devices 76 for securely fixing the cooking vessel C existing in the prescribed position to the annular frame 64. Further, the cooking vessel C in the upward open state is held downward and the nozzles 80 for internal washing which wash the inside of the vessel by injecting the washing water therein are supported by oscillatable nozzle arms 82 and are mounted at the annular frame 64. As a result, the execution of rinsing is made possible without allowing the washing water to stagnate in the moving tank.
