Conventionally, a vertical grinding type rice mill has been used as a rice mill for sake brewing rice. A non-porous milling cylinder with a supply unit at the top and a discharge unit at the bottom is equipped with a grinding-type milling roll (Kongo roll). Milking sake rice with a degree of whiteness
With this type of vertical grinding rice mill, the yield is 75%.
%, The hardness of the rice grain surface increases, the milling does not proceed, and the surface of the rice grain presents a fine rough surface, increasing the frictional resistance, and the rice grains in the milling chamber formed between the milling cylinder and the milling roll. The flow of the rice becomes slow and becomes clogged (so-called "squeak"), and a large amount of rice grains that no longer flow down to the refining chamber stagnate in the vicinity of the supply section, and at the same time, the operation becomes impossible. As described above, a large gap is formed in the supply section above the milling roll in order to create a “runaway” of the rice grains staying in the vicinity of the supply section. However, restarting is not easy due to a large amount of clogged rice grains. Therefore, as shown in FIG. 2, there is known a pressure plate in which a central portion of a pressure plate is fixed to be raised to provide an inclined portion so that rice grains can easily flow into the refining chamber (actually 1-). 41476 etc.).

01In the case where the conical raised portion 102 for guiding the rice grains is integrally provided on the upper part, the frictional force between the raised portions 102 rotating with the roll 101 and the rice grains is increased, and especially when restarting. Not only does this require more power (as a result, the temperature of the rice grains further rises), but also the state of fluidity changes with the progress of the milling of the rice grains, and the supply amount fluctuates, causing problems such as uneven milling. In view of these points, the present invention provides a smooth supply of rice grains without the need for extra power, and thus without unnecessarily increasing the rice grain temperature.

The space between the lower outer cylinder 11 and the lower outer cylinder 11 is defined as a refining chamber 19, and the lower outer cylinder 11 is appropriately provided with a resistance claw 20 facing the refining chamber 19. On the other hand, in the upper outer cylinder 9, there is provided a cone-shaped drifting cap 22 fixed to the inner wall of the upper outer cylinder 9 as a non-rotating portion via a stay 21. That is, the cap body
The top 22 a of the nozzle 22 is positioned at the center of the supply port 10, and a connection tube 23 abutted on the press plate 18 of the whitening roll 14 is loosely fitted into the opening at the lower end thereof through a slight gap, and the cap 22 A grain feeding path 45 is formed between the outer cylinder 9 and the upper outer cylinder 9. The shape of the grain feeding path 45 in the longitudinal section is formed so as to gradually become narrower downward so that the cross-sectional area of the grain feeding path 45 becomes the same everywhere. A main shaft 13 for rotating the refining roll 14 is rotatably provided on the drive unit 4 by an upper bearing 24 and a lower bearing 25, and a pulley 26 mounted on the main shaft 13 is linked with a main motor (not shown).・ Connected. The bran removing section 5 is composed of a sieve (sieving) 28 in which wire meshes 27A and 27B having different meshes are laid, and is tilted by a shaft 29 and a leaf spring 30 so that the supply side is high and the discharge side is inclined near. Sieve
The back surface of 28 is connected by a rod 34 to a cam 33 driven by a motor 31 and a cam pulley 32. Also, sieve 28
A drain gutter 35 is provided on the supply side, a discharge gutter 36 is provided on the discharge side, and a bran receiving gutter 37 is provided below the wire meshes 27A and 27B. In addition, the bran receiving trough 37 is connected to a bran removing fan 40 via a flexible pipe 39, and the receiving trough 35 is connected to a discharge gutter 42 fixed to the outside of the discharge port 12 via a communication gutter 41, respectively. In the refining room 19 near the discharge port 12, a kick is made.
43 is provided, and a resistance plate 45 biased by a weight 44 toward the discharge port 12 is mounted outside the discharge port 12. Hereinafter, a specific operation in the above embodiment will be described. The rice suitable for sake brewing is put into the tank 2, the main motor and the motor 31 are started, the valve 8 is gradually opened by the flow control handle 7, and the grain feeding passage 45 in the upper outer cylinder 9 and the lower feeding cylinder 45 in the lower outer cylinder 11 are opened. The operation is performed in a state where the rice polishing room 19 is filled with rice grains. That is, the rice grains flowing down from the tank 2 to the supply port 10 glide on the inclined surface of the cap body 22 while being evenly distributed in the circumferential direction by the drifting cap body 22 and direct the grain feed path 45 to the milling chamber 19. Is guided and guided. When the rice grains reach the vicinity of the upper part of the rotating whitening roll 14, they flow into the whitening chamber 19 while revolving due to the rotational force, reach the lower end of the whitening chamber 19 while being ground by the grinding roll 17, and are kicked out. The liquid is sequentially discharged from the discharge port against the resistance plate 45 by the claw 43. The discharged rice grains are supplied to the sieve 28 through the continuous gutter 41 and the receiving gutter 35, and the broken rice and bran that have leaked out of the wire meshes 27A and 27B fall into the bran receiving gutter 37 and are removed by the bran removing fan 40. Pneumatically transported to a bag filter. On the other hand, the rice grains separated from the bran are put into the fryer 6 through the discharge gutter 36 and the hopper 38, returned to the tank 2 again, and remilled. Thereafter, the milling is repeated in the same manner until a suitable degree of milling (yield) is achieved, but even if the milling progresses and the friction coefficient of the rice grains becomes large, the rice grains near the supply port 10 are used for drifting. The rice grains do not flow with the cap body 22, so the rice grains
45 flows smoothly at almost the same flow rate. In addition, grain feeding road
The fact that the 45 cross-sectional areas were formed almost identical also greatly contributed to the smooth supply of rice grains. According to tests conducted by the present inventors, the power consumption up to a yield of 68% is lower than that of a conventional power supply without a cap for floating grains.
168KW ・ H, about 133KW ・ H when the cap is provided
20% reduction, up to 50% Narudome, the conventional 611K
438KW · H with a cap compared to W · H, a reduction of about 30%. Therefore, even with the same electric motor, the creaking phenomenon is unlikely to occur, and even if creaking occurs, restarting can be easily performed by discharging rice grains to a certain extent from the outlet 12.
