Therefore, only rotating the rice washing part around the support shaft to disengage the rice washing part from the apparatus main body exposes the part of the rice washing part connected to the dehydration part and the part of the dehydration part connected to the rice cleaning part. Can be put into a closed state. This makes it easier to disassemble and reassemble the rice washing and dehydration units (depending on the structure of the rice washing and dehydration units, it may be necessary to clean and wash the rice washing and dehydration units without disassembling the rice washing and dehydration units). Therefore, maintenance of the non-washed rice manufacturing apparatus (including cleaning and washing, as well as disassembling and reassembling the rice washing section and the dehydration section) can be facilitated.

Further, by rotating the rice washing part with respect to the apparatus main body as described above, it is possible to expose the connecting portion of the rice washing portion with the dehydrating portion and the connecting portion of the dehydrating portion with the rice washing portion. It is possible to properly perform the maintenance of the rice washing section and the dehydration section, even if the sizes of the section and the dehydration section are not sufficiently large. Therefore, it is possible to reduce the size of the non-washed rice manufacturing apparatus.

A non-washed rice production apparatus according to a second aspect is the non-washed rice production apparatus according to the first aspect, characterized in that only the apparatus main body other than the rice washing section is covered with a cover.

In the non-washed rice producing apparatus according to the second aspect of the present invention, since the rice washing portion is not covered with the cover, it is easier to disassemble and reassemble the rice washing portion (the rice washing portion without disassembling the rice washing portion). The cleaning and washing of the rice can be further performed), and the maintenance of the non-washed rice manufacturing apparatus can be further facilitated.

Furthermore, since the main body of the apparatus is covered with the cover, the safety of the non-washed rice producing apparatus can be maintained.
