BACKGROUND OF THE INVENTION
The present invention relates to a rice sharpener that is polished with anhydrous water.
[0002]
[Prior art]
In general, rice is washed to cook rice, but in a commercial grain washing device, the rice washing process is important in the equipment that removes rice bran and separates rice grains and rice bran. It is a complicated process and a very time-consuming process. Therefore, there are many devices that automate this rice washing process and save labor.
[0003]
However, those that stir water and rice by mechanical force are likely to damage the rice, and the water mixed with rice bran cannot be quickly separated from the rice, and the rice has absorbed the smelly water and cooked rice Will become rice with a bad smell, and the fatty acid contained in the rice cake will be oxidized to increase the warming odor. Also, there are some that rub the rice together with the water pressure in running water, but it requires a large amount of water and also causes sewerage pollution.
[0004]
In addition, there is wash-free rice that is sold with the koji removed, but wash-free rice that uses water is inferior in taste because it is dried and distributed after using water, and wash-free rice that uses sticky koji is a system However, the use of rice bran is very large and difficult to handle as general household and business equipment, and the system using only non-washed rice is relatively simple, but there is a problem with the taste performance of the non-washed rice itself. was there.
[0005]
Conventionally, rice sharpeners that polish rice with anhydrous water have been constructed as shown in FIG. Hereinafter, the configuration will be described. FIG. 9 shows the structure of the sharpening part 51 of the rice sharpener. The outer periphery of this sharpening part is a cylindrical shape that is open up and down, so that rice cannot pass through it, and rice cake, rice flour, and other dust pass through it. A separation part (not shown) having a hole of a size that is separated by a gap through which about one or two grains of rice can pass and an outer hopper is formed so as to form a cylindrical donut-shaped closed space on the outer periphery of the separation part (Not shown).
[0006]
As shown in FIG. 9, the rotating disk 53 covers the bottom surface of the polished rice hover, and a cylindrical body 54 having an outer periphery formed in a brush shape with a gap above the rotating disk 53 is installed. A cylindrical shape 58 is provided on the upper surface of the rotating disk 53 from the center side to the outer peripheral side so as to rotate together with the rotating disk 53. The rotating shaft 52 is connected to the cylindrical body 54 via connecting members 56 and 57, and the rotating shaft 52 and the rotating disk 53 are connected by a pedestal 55 (see, for example, Patent Document 1).
[0007]
The operation in the above configuration will be described. When rice grains of polished rice for the purpose of washing the rice are put into the polished portion and the rotating disk 53 and the cylindrical body 54 are rotated, the rotation of the rotating disk 53 and the cylindrical body 54 is rotated. As a result, the rice at the bottom of the polished portion is given centrifugal force and presses the rice grains against the side surface of the cylindrical body 54, so that it rises along the side surface in order and rises between the side wall of the separating portion and the cylindrical body 54. Accelerate the rubbing of rice grains by centrifugal force and scrape the rice cake or rice surface powder. The separated rice cake is discharged into the closed space of the outer hopper through the hole of the separation part, and the rice cake and rice are separated, and the rice is washed with anhydrous water.
