As described above, according to the present invention, since the rice cooking means is constructed in multiple stages in the vertical direction, it is possible to produce a large amount of rice in a small installation space, and the transportation means can be used. The rice cooker holding means can easily move the rice cooker to a position corresponding to each stage of the rice cooker, and from that position to the rice cooker inside the housing, the rice cooker can be easily installed at a high position. Even if there is any, the rice cooker can be moved and installed without any trouble, and manual work such as lifting the rice cooker to a high position unlike the conventional case is not required, and work efficiency can be significantly improved.

Further, the rice cooker in the rice cooker can be easily taken out by moving the transfer means upward and sliding the rice cooker holding means forward, and the rice cooker taken out at a high position. Even after that, by lowering the transfer means, the rice in the rice cooker can be easily unloaded.

Further, the transfer means is automatically stopped at the upper or lower level stop position depending on whether or not the rice cooker is held by the rice cooker holding means by the sensor provided in the transfer means. Therefore, the rice cooker can be immediately installed in the rice cooker or the rice cooker can be taken out of the housing from each of the stop positions, and the work efficiency can be further improved.

Further, since the transfer means can be stopped at an arbitrary position, the rice unloading work can be performed at the position where the work is most easy.
