Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice-milling machine for removing rice bran and aleurone layers from milled rice or a commercially available milled rice, and more particularly to an improvement in the rice-milling member.

[0002]

BACKGROUND OF THE INVENTION The present inventors have obtained rice-free rice which can be cooked without the need to grind rice using water, by further removing the bran and paste layers from milled rice or commercially available milled rice. As shown in FIG. 5, a rotating disc 3 attached to a rotating shaft 2 and a rotating circular plate attached to the rotating shaft 2 are also used for the agitation type rice polishing machine (non-washing rice machine). The polishing rice member 1 composed of the cylindrical body 4 which rotates together with the plate 3 was developed (see Japanese Patent Application No. 2000-80827). Rotary axis 2
A drive shaft of a motor to be described later is fitted into the hole, and the cylindrical body 4 is connected to the rotating shaft 2 via a radial connecting plate 5, and the outer peripheral surface thereof is brushed by brushing or planting.

The rice polishing member 1 is installed in a rice polishing hopper of a rice polishing machine, for example, as shown in FIG.
0-239223). The rice polishing machine 6 is provided below the rice storage tank 7 and the rotary measuring and dividing device 8, and includes a rice bran container 9 and a rice polishing hopper 1 disposed inside thereof.
0, and the polishing rice member 1 installed therein.
The rotary weighing / squaring device 8 includes a squaring structure 11, a rotary weighing unit 12, and a weighing receiver 13.
Has a cut-out section (outflow port) 11a, a rotary measuring section 12 has a cylindrical hole (measuring box) 12a penetrating vertically, and a measuring receptacle 13 has an opening 13a.
When the rotary measuring unit 12 is rotated by a motor or the like at a predetermined angle with the rice stored in the rice storage tank 7, the rice that has entered the measuring box 12 a through the outlet 11 a is cut off, and the measuring box 12 a is further opened. Weighing box 1
The rice in 2a passes through the opening 13a and the lower rice polishing hopper 1
Flow down to 0.

The polishing rice hopper 10 has a substantially whole side wall and a bottom wall formed as a bran removing portion having a large number of small holes formed therein.
Fall into. Polishing rice discharge opening 14 of polishing rice hopper 10
Is normally closed by a valve body 15 which moves forward and backward by a solenoid (not shown). In the bran container 9, a polishing rice opening 16 serving as a rice discharge passage is formed at a location corresponding to the rice discharge opening 14, and a bran opening 17 serving as a bran discharge passage is formed at another location. Not connected to a suction device. Note that the outer diameter of the rotating disk 3 of the polishing rice member 1 is set slightly smaller than the inner diameter of the polishing rice hopper 10 (there is a minute gap to the extent that rice does not bite).
The upper surface is set at the same height as or slightly higher than the polishing rice discharge opening 14. A drive shaft 18 of a motor (not shown) is fitted in the hole of the rotating shaft 2.

When the motor of the rice polishing member 1 is operated and the suction device is operated at the same time, the rice is circulated (indicated by an arrow) in the rice polishing hopper 10 to be stirred and polished. That is, as described in the aforementioned Japanese Patent Application No. 2000-80827, the rice on the rotating disk 3 is pushed in the outer peripheral direction by centrifugal force, and the rice reaching the outer periphery is polished by the pressure of the rice being pushed one after another. The rice that rises through the space between the hopper 10 and the cylindrical body 4 and then reaches the upper end is released from the pressure, flows down toward the center of the cylindrical body 4, and is again put on the rotating disk and pushed outwardly. . When the rice rises between the polishing hopper 10 and the brush-like outer peripheral surface of the cylindrical body 4 during the circulation, the rice is subjected to the polishing operation. On the other hand, the paste layer or the like peeled from the rice enters the bran container 9 through the small holes of the polishing rice hopper 10 by the suction device, and is sucked and discharged from the bran opening 17. When the scheduled rice polishing level is reached, the valve body 15 is retracted, and the rice stirred in the rice polishing hopper 10 is discharged through the rice polishing opening 14 and the rice polishing opening 16 by centrifugal force.

[0006]

According to the above rice polishing machine,
The rice bran and the aleurone layer are removed from the milled rice, so that it is possible to obtain unwashed rice that can be cooked without rice sharpening using water. However, this polishing rice machine may be used for small-scale processing (for example, up to about 0.5 to 2 sets per processing) for home use. When the capacity is increased (for example, about 3 to 1 square volume per processing), the circulation of the polished rice in the polishing rice hopper becomes insufficient, and the processing time of the polishing rice becomes longer, There has been a problem that it is not possible to obtain rice that has not been washed so that rice can be cooked without sharpening. It also takes time to discharge after polishing rice. An object of the present invention is to solve such a problem.

[0007]

Means for Solving the Problems When the size of the rice polishing machine is increased and the diameter of the rice polishing hopper, the cylindrical body and the rotating disk are increased, the circulation of rice in the rice polishing hopper becomes insufficient. It was found that the pressure for pushing the rice placed on the rotating disk to the outer peripheral side was insufficient, so that the rice was unlikely to rise between the polishing rice hopper and the cylindrical body 4. The present invention has been made based on this finding. That is, the polishing rice member according to the present invention is a rotary disk that covers the bottom surface of the polishing rice hopper, and is installed with a gap above the rotary disk, rotates with the rotary disk, and has a brush-shaped outer periphery. And a ridge extending from the center to the outer periphery is provided on the upper surface of the rotating disk. The ridges on the rotating disk are curved with a delay with respect to the rotation direction, and are inclined with respect to the rotation direction between the cylindrical body and the rotation shaft to which the cylindrical body is connected. It is desirable to provide a pressure member having a surface. This pressure member can also serve as a connecting member for connecting the cylindrical body and the rotating shaft.

[0008]

1 and 2 show a rice polishing member 21 according to the present invention, in which a rotating disk 23 mounted on a rotating shaft 22 and a rotating disk 23 mounted on the rotating shaft 22 are also shown. And a cylindrical body 24 having a circular cross section that rotates with the cylindrical body.
The rotating disk 23 is attached to the rotating shaft 22 via a disk-shaped pedestal 25. The pedestal 25 has a role of supporting a connecting plate 26 described later. The cylindrical body 24 is connected via a pair of connecting members 26 extending radially from the rotation shaft 22, is located above the rotating disk 23 with a gap therebetween, and the outer peripheral surface of the cylindrical body 24 is The brush is formed by brushing or flocking. The connecting member 26 is plate-shaped and inclines arbitrarily in the rotational direction (indicated by an arrow in FIG. 2), and enters the cylindrical body 24 as the “pressure member having a surface that is arbitrarily inclined”. It pushes rice down and promotes its circulation. Here, the expression “inclining forward in the rotation direction” means that the upper side of the connecting member 26 is located at a position advanced from below in the rotation direction (the upper side is inclined so as to be forward).

On the upper surface of the rotating disk 23, a ridge 27 extending from the center to the outer periphery is provided.
And extends from the outer peripheral surface thereof in a curved manner with respect to the rotation direction, and serves to push the rice placed on the rotating disk 23 to the outer peripheral side. Here, the curve extending in a delayed manner means that the outer peripheral side of the ridge is delayed from the center side with respect to the rotation direction (extended rearward from the radial direction r (see FIG. 2)). The polished rice member 21 is different from the polished rice member 1 shown in FIG. 5 in that the protrusion 27 is formed.

The polishing rice member 21 has a cylindrical side wall, similar to the polishing rice member 1 (see FIG. 6), and has a small number of small holes formed in at least a part of the side wall and the bottom wall. It is installed in a rice hopper having a part and rotates. This polished rice member 21
With the use of a rotary disc 2
3. The pressure to push the rice on top to the outer circumference increases,
With this pressure, the rice rises between the polishing rice hopper 10 and the cylindrical body 24, and the rice R is sufficiently circulated as shown in FIG.

In the above example, the plate-like connecting member 26 is used.
Because it is arbitrarily inclined with respect to the direction of rotation,
The pressure for pushing down the rice in the tubular body 24 downward increases, but it is not necessary to be limited to this form. Needless to say, the present invention includes providing a pressure member having a surface which is inclined independently of the connecting member. In the above example, since the ridges 27 provided on the rotating disk 23 are curved and extended with a delay in the rotation direction, the pressure for pushing the rice on the rotating disk 23 to the outer peripheral side increases. And, the impact on the rice is reduced and the generation of powdered rice is suppressed, but it is not necessary to be limited to this form, and if the ridge is not curved,
Alternatively, the present invention includes a case in which the light source extends linearly in the radial direction as shown in FIG. Further, the pedestal 25 is not essential.

[0012]

According to the rice-milling member of the present invention, it goes without saying that the rice-milling machine is intended for small-scale processing intended for home use.
Even if the capacity is increased for commercial use, the rice in the polished rice hopper is sufficiently circulated. Therefore, necessary rice polishing is performed on the introduced rice polishing, so that it is possible to obtain a non-washed rice that can be cooked without rice polishing using water, and it is also possible to shorten the rice polishing time and the discharge time.
