糠装置へ送られる。Next, the operation of the above configuration will be described. The grain is sent via a supply gutter 28 to a supply port 29 provided in the lower part of the small-diameter machine frame 25. When the electric motor 11 that drives the vertical shaft 3 is started, the grain is forced by the screw conveyor 4 into the grain supply unit 8
Is supplied to the spiral rotator 5 and the grains are sent to the grain mill 7 by the spiral rotator 5. Therefore, the grains are stably and uniformly supplied from the spiral trochanter 5 to the grain mill 7. In the grain refining chamber 7, the grain is refined by the polishing action caused by the rotation of the friction grain trochanter 6, and the grain refined reaches the grain discharging unit 9. At this time, the resistance lid 17 of the bowl accuracy adjusting device 16 suppresses the outflow to the discharge gutter 18, and the bowl accuracy can be adjusted by changing the restriction of the resistance lid 17. Then, the grain is sent from the discharge gutter 18 through the scrape conveyor 19 to the next step. On the other hand, dust such as bran generated by the polishing action in the grain refinery chamber 7 is discharged from the through hole of the porous wall debulking and polishing white tube 2 and sent to the bran collecting chamber 22, where it is sucked and pressure-fed by the blower 23, and discharged. It is sent to a bran collecting device such as a cyclone (not shown) through the bran pipe 24.

生を防止することができる。Grain in the grain mill 7 does not easily flow down due to a small-diameter machine frame 25 provided below the machine frame 26 of the porous wall bran removal whitening tube 2 in which the spiral trochanter 5 is installed. Due to the wall 27, even if the grain supply is temporarily stopped or reduced, it does not drop rapidly to the bottom of the machine, and if the supply flow rate is immediately restored, grain clogging and uneven mashing will almost never occur. Absent. Further, when the pressure in the grain refinery chamber 7 becomes a certain level or more during grain polishing, the opening / closing plate 30 opens against the biasing device 31 due to the pressure of the grain,
Overflow and fall from the opening of the grain into the supply gutter 28, and the supply port 29
Is re-fed by the screw conveyor 4. Therefore, even if the pressure in the grain refinery chamber 7 exceeds a certain level, the grains can be overflowed and the pressure can be released, and the occurrence of broken rice or clogging can be prevented.

とがなく、安定した搗精が実現できる。According to the vertical shaft type grain refiner in the present invention, since the screw conveyor is axially mounted on the lower shaft of the spiral trochanter, it is stable and uniform to the grain supply unit and the grain chamber at the lower end of the spiral trochanter. It is possible to supply the grains efficiently, and therefore, it is possible to completely prevent the unevenness of the grain in the grain refinement chamber due to the uneven supply of the grains, and at the same time, the cylindrical machine frame in which the screw conveyor 4 is installed. Since the diameter is smaller than that of the machine frame in which the spiral trochanter is installed, even if the flow rate of the grain fed into the grain refiner changes, the grain in the grain mill immediately flows downward. It is possible to realize stable seisei without any problems.
