2. Description of the Related Art In such a rice polishing apparatus, a rotating body on which a brush is planted is rotated in a state of having an appropriate elasticity so that the tip of the brush is brought into contact with the surface of the rice grain and remains on the surface of the rice grain. It is designed to remove bran. Conventionally, as shown in FIG. 8, the brush 42 is partially implanted in the circumferential direction of the rotating body R in the axial direction of the rotating body R, and the surface of the implanted portion 43 ′ on which the brush 42 is implanted is It has a uniform curved surface or flat surface over the entire surface (for example, see Japanese Patent Application Laid-Open No. 5-249).

The rice polishing room 40, the vent 13a, the bran collection chamber 7, and the rice bran discharge chute 4f sequentially flow, and are discharged from the discharge port of the suction fan 29 to the outside. As a result, the bran separated from the rice grains and the brush 42 are worn away, and the separated residues are also discharged.

Accordingly, the ventilation hole 43c corresponds to a blowout port for blowing air to the brush 42 in the direction of flocking, and the blowout port 43c is formed by the suction fan 29 and the pressure-feed fan 31.
The ventilation means which ventilates to this is comprised. Incidentally, the brush 42 is worn away and residue is generated.
When a 0 t rice grain is polished, the brush 42 is only 1 mm.
As can be seen from the fact that it is only worn to the extent, the residue is extremely small, and the residue is discharged together with the bran by the ventilation by the suction fan 29 and the pressure feeding fan 31.

Further, by the suction action of the suction fan 29, air is sucked in from the outside through the ventilation hole 15 and is caused to flow along the inner surface of the cylindrical portion 4a, so that the transparent portion of the cylindrical portion 4a is made of bran or the like. It is configured to prevent fogging. By adjusting the damper 32, the air volume sucked by the suction fan 29 is adjusted to be larger than the air volume blown by the pressure feeding fan 31, so that the inside of the polishing rice chamber 40 is maintained at a negative pressure. I have. Since air is sucked in from the ventilation holes 15 and other gaps, specifically, the suction fan 2
9 is about 1.3 times the amount of air blown by the fan 31.

By the cooperation of the suction fan 29 and the pressure feeding fan 31, the flow of the rice grain cooling air flowing through the grinding rice chamber 40 is increased by allowing the rice grain cooling air to flow through the polishing rice chamber 40. At the same time, by increasing the flow rate, the flow state and posture of the rice grains flowing upward in the polishing rice chamber 40 are disturbed, so that the polishing is performed more favorably. Further, since the pressure feeding fan 31 is configured to supply the rice grain cooling air to the air reservoir 33, the pressure of the rice grain cooling air can be increased in the air reservoir 33 and the pulsation is suppressed. can do.

Next, a bran separation apparatus for separating bran from rice grains polished by the above rice polishing apparatus will be described with reference to FIGS. When the rice is polished with the above-mentioned rice polishing apparatus, almost all the bran is discharged by the ventilation by the suction fan 29 and the pressure feeding fan 31, and almost no bran remains in the rice grains,
Although there is no problem in actual use, if the bran is further removed by the bran separation device described below, the commercial value can be further improved. In addition, even if the residue of the brush 42 remains, it is removed together with the bran.

The sorting plate 51 is provided with side walls 51b at three of the four side edges other than the side edge functioning as the discharge portion 51a, and at the bottom portion the side where the discharge portion 51a is located. A large number of piano wires 51c are stretched in parallel across the edge portion and the side edge portion facing the edge portion at such an interval that rice grains do not fall. Below the sorting plate 51, a bran receiving tray 52 having a discharge port 52a is integrally attached in a state spaced from the bottom thereof. The sorting plate 51 is provided with four links 5 in an inclined posture in which the discharge portion 51a is at the lowest position.

A pulley 59 that rotates integrally with the eccentric bearing device 58 and an output shaft of the electric motor 60 are interlocked and connected by a belt 61.

Then, by operating the electric motor 60 to rotate the eccentric bearing device 58, the sorting plate 51 is swung up and down and laterally, and the rice grains supplied from the hopper 55 to the sorting plate 51 are removed. In the process of flowing down toward the discharge section 51a, rice grains and bran are separated, the rice grains are taken out from the discharge section 51a, and the bran is dropped into the bran tray 52 between the piano wires 51c and taken out from the discharge port 52a. It is configured in.

(B) In the axial direction, the shape of the line formed by virtually connecting the tips of the brushes 42 can be variously changed in a state of being symmetric with respect to the center line L. For example, it may be a straight line or a bent line formed by the oblique sides on both sides of the trapezoid and the upper base. (C) The number of the flocking members 43 provided on the outer peripheral portion of the polishing rice roll 41 in a state of being dispersed at intervals in the circumferential direction does not matter. (D) In the above embodiment, the long flocked member 43 is provided in such a position that its longitudinal direction is parallel to the axis of the polishing rice roll 41. However, instead of this, the long flocked member 43 is used. May be provided such that the longitudinal direction thereof intersects the axis of the polishing rice roll 41. (E) A plurality of flocked members 43 may be provided on the outer periphery of the polishing rice roll 41 in a staggered arrangement. (F) In the above embodiment, the protrusion 43 a is
Although the case where it is provided at both ends in the circumferential direction of the polishing rice roll 41 in the above is exemplified, instead, the protrusion 43a is
It may be provided only at the end of the flocking member 43 on the tip side in the rotation direction of the polishing rice roll 41. However, in this case, when the brush 42 is worn, it is necessary to replace it with a new flocked member 43. (G) The rice polishing roll 41 may be provided in a direction in which the rice polishing roll 41 is inverted in the axial direction. In this case, when the brush 42 is worn, the polishing rice roll 41 is reversed instead of reversing the flocked member 43. (H) The brush 42 can be formed of various materials other than the materials shown in the above embodiment. For example,
It can be formed of a metal material such as stainless steel, a resin, or a material such as pig hair. In the case where the brush 42 is formed of a metal material, it is preferable that the thickness of the brush 42 be about 60 μm, since the elasticity is suitable for shaving off bran. (I) In the above-described embodiment, the present invention is applied to a so-called vertical rice polishing apparatus in which the polishing rice roll 40, the transport screw 11, and the cylindrical shaft portion 8 which are coaxially connected are provided with their shaft cores directed vertically. Although the case of application is illustrated, the present invention can be applied to various types of polishing machines other than the above. For example, a so-called horizontal rice polishing device in which the polishing rice roll 40, the conveying screw 11, and the cylindrical shaft portion 8 which are coaxially connected are provided with their axes oriented in the horizontal direction, or hard wood (instead of the grindstone 17) For example, the present invention can be applied to a rice polishing apparatus provided with a polishing member made of oak.

Incidentally, reference numerals are written in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
