る。2. Description of the Related Art At present, rice is generally provided to consumers in the state of milled rice that has just been processed by polishing. In the state of this polished rice, firstly, there is a problem that it is difficult to store the polished rice for a long period of time. That is, if stored for a long period after pearling, there is a problem that the oil content contained in the rice is oxidized and the taste is deteriorated to make it unusable. Secondly, before the consumer cooks rice, the polished rice is washed with water, but the bran adhering to the rice is discarded together with the drainage, and the sewage becomes high-enrichment water.
There is a problem that rivers are polluted and contribute to pollution problems. Thirdly, it is complicated for the consumer to wash the polished rice with water before cooking rice, and nowadays, the washing work of the polished rice is attempted to be simplified as much as possible in a general household. There is a request to eliminate it if possible.

While the carry-in screw 8 is rotating, the defatted rice bran B, the polished rice A,
The pressurizing material C is sequentially fed into the rotary drum 10. The defatted rice bran B and the milled rice A carried into the rotary drum 10 are pressed materials C.
While being subjected to heavy pressure, the rotary drum 10 is rotated and polished as the rotary drum 10 rotates. At this time, the rotation speed of the rotating drum 10 is, for example, 30 rpm, and the rotating drum 10 rotates relatively slowly. Therefore, the rice polishing A, the defatted bran B, and the pressurizing material C in the rotating drum 10 are as shown in FIG. In addition, it is rotated and lifted, and when it is lifted to some extent, it makes a slanting motion. At this time, the polished rice A is polished by the defatted bran B (downhill polishing distance), and at the same time, the defatted bran B enters between the rice grains, and the oil and fat content and sugar content of the polished rice A are appropriately removed.

As shown in the table obtained by polishing rice with the stone disclosed in the invention related to No. 0, since the stone and the rice were separated, the polishing could not be averaged.
Since the metal has a high specific gravity, it concentrates at the center of the rotating drum, but if there are small holes, a large amount of pressed metal can be used, the polishing can be made uniform, and the turbidity also decreases.

However, such an action is not limited to the defatted bran and it is not limited to fusuma bran. It may be an oil / fat absorber such as powder, granules, etc. artificially manufactured to absorb the oil / fat, or buckwheat.

The rice is carried into the hopper 16, sequentially dropped from below the hopper 16, and the polished rice is sequentially placed and conveyed on the belt conveyor 20 driven by the four rollers 17.
At this time, the belt conveyor 20 is formed of a net, and the control plates 21, 21 are formed on the belt conveyor 20.
Are arranged at regular intervals, and a dustproof cover 18 is covered above the air injection pipe 18
a is connected to this cover 18. A cover 19 is provided below the belt conveyor 20 of the net, and a blower (suction machine) 22 is provided in the lower center portion of the cover 19.
The blower 22 is provided with an air discharge pipe 19
a is connected. Because it is configured like this,
The milled rice A conveyed on the belt conveyor 20 receives the blast air from the air blast pipe 18a, and as a result, the milled rice A
The bran and fine powder adhering to is passed through the net of the belt conveyor 20 and discharged by the blower 22. At this time, fine powder of milled rice A is also sucked at the same time. In this way, the bran and fine powder are removed, and the refined rice is carried out from the belt conveyor 20. During the air cleaning of the polished rice A, since the control plate 21 controls the force of adsorbing the purified rice on the net to rotate the rice, the polished rice A is thoroughly cleaned.

It is a liter, an octagon, a direct line of 195 mm, and a length of 220 mm. As a result of placing 1 liter of polished rice A and 1.5 liters of defatted bran B in a rotating drum (polishing machine) and sequentially increasing the amount of pressurized metal, the result was 1.2 liters, which was the maximum value to be buried in defatted bran B. Next, as a result of performing downhill polishing rice and performing turbidity inspection, 1.2 liters of the pressurizing material C was the optimum amount.
Further, the degreasing bran B is 1.5 liters, and the minimum value in which the pressurizing material C is buried is considered to be the optimum amount.

る。The rice turbidity is 151, and from the above Table 1, it is considered that 1.2 liters of the pressurizing material C is suitable. The optimum amount of the degreasing bran B is considered to be the minimum value at which the pressurizing material C is buried. Experimental Example 2 From the data in Table 1, it was found that the optimum amount of the degreasing bran B was the minimum value at which the pressurized metal was buried. That is, add 1 liter of polished rice A and 0.6 liter of pressurized metal to the rotating drum,
As a result of increasing the amount of the defatted rice bran B in sequence and observing it by rotating, the minimum value of the defatted rice bran B was 1.2 liters. After further increasing the amount of pressurized metal and determining the minimum value of the degreasing bran B respectively, the results of turbidity test after down-grinding the combination of each
As shown in Table 2, defatted bran B for 1 liter of polished rice A
1.5 liters and 1.2 liters of pressurized metal were most effective. However, in the case of implementation, it will be finally decided in consideration of economical efficiency, rice variety, new rice, old rice, and the like.

環境に対して優しくすることができる。As described above, in the present invention, since the degreasing bran or the fat and oil absorbent is subjected to heavy pressure with the pressurizing material for polishing, the bran of the polished rice is removed and present in the groove of the polished rice. The soybean bran is removed, and the oil content of the polished rice is removed by the defatted bran or the fat and oil absorber, and as a result, refined rice is obtained.
The surface of the refined rice thus obtained is almost completely bran-free,
Oil and fines have been removed. Therefore, since the oil content is removed, refined rice is not oxidized during storage and its quality is not deteriorated, and long-term storage is possible. Also,
This refined rice is about the same as being washed with water before cooking,
Since rice bran and fine powder have been removed, it is not necessary to wash refined rice with water before cooking rice in a general household. Furthermore, since washing with water is not required, the bran is not discarded together with drainage, the river is not polluted, and there is no pollution problem.
Can be environmentally friendly.
