Driving rice mill:
After turning the resistance handle 23 and setting the desired milling degree, the motor 3 is started to rotate the milling roll 5 and the brown rice in the hopper 41 is fed into the raw material supply port 42. It rises while rotating inside, flows down into the white rice bran 33 against the pressing force of the resistance disk 27, and is accommodated in the white rice container 40.

  The rice cake discharged from the wire removing net 7 collides with the milled rice cylinder 16 and falls into the rice wine container 18 while changing its direction. At this time, since the wrinkles do not contact the polished rice outer cylinder 12, the wrinkles do not adhere and solidify on the inner surface of the outer cylinder 12. The white rice container 40 and the rice bran container 18 are arranged in line symmetry with respect to the central axis of the rice milling machine. For example, the white rice container 40 is provided on the right side of the central axis of the rice milling machine, and on the left side thereof. A basket 18 is provided.

Cleaning (disassembling) rice mill:
When cleaning the rice mill 1, when the handle 39 is rotated in the opening direction, the engaging portion 36 p of the clip 36 is locked to the locking portion 34 s of the flange portion 34 and cannot be rotated any further. Then, as shown in FIG. 3 (B), the pressing plate 39a is disengaged from the pressing portion 20p of the base 20, so that the lock between the pressing plate 10 and the polished rice outer cylinder 12 is released.

  Next, when a finger is applied to the finger hooking portion 16h of the rice milling inner cylinder 16 and pulled toward the front, the resistance device set T and the rice milling screen set S which are integrated via the pressing plate 10 can be easily removed from the rice milling outer cylinder 12. Can be extracted. Since the spring 44 is provided between the bottom of the boss 38 and the head of the bolt 37, the handle 39 can be smoothly turned.

  The left and right clamp-like projections 32 of the extracted resistor device set T are sandwiched between fingers and pressed inward to release the engagement between the clamp-like projection 32 and the clamp hole 10a of the holding plate 10, and the resistor device When the set T is pulled in the direction away from the presser plate 10, the latching portion 29 comes out of the support slot 10d.
