て別件へ排出される。A conventional vertical shaft type thickness-cutting type grain 1 will be explained with reference to FIG. Reference numeral 3 indicates a vertical shaft type friction cutting type grain milling machine, in which a main shaft 41 is rotatably provided in a porous walled bran removal and polishing cylinder 40 that is installed upright.
A spiral trochanter 42 and a grinding grain trochanter 44 having stirring protrusions 43 on the top and a spiral trochanter 42 are mounted on the bottom and the grain trochanter 44, respectively. The grains are supplied to the spiral rotor 42 from a grain supply section 47 provided on one side wall of the machine frame 46 via the grain feeding trough 45, and the rice grains are transported to the grain milling room 48 by the spiral rotor 42. In the grain milling room 48, the grains are milled under the 1Q traversal action generated by the rotation of the friction grain milling trochanter 44, and the milled grains are discharged from four discharge ports through a discharge gutter 50 to another part.

う問題点があった。However, in the conventional vertical shaft type friction cutting grain milling machine as described above, pressure is applied uniformly in the vertical direction inside the grain milling chamber 48, so the rice grains do not pulsate and the stirring action is sufficiently performed. There was a problem in that some grains were not easily milled and were discharged along with the friction milling trochanter 44 while being incompletely milled, resulting in uneven graining. In addition, even if the resistance pressure is increased using the resistance adjustment device in the discharge section to improve the pounding accuracy, the rice grains will not revolve, and the friction between the grains will become ineffective, and the grain temperature will only increase, resulting in less effective friction. There was a problem that the milling action could not be performed and the milling efficiency and yield were low.
