Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice polishing machine for polished rice used in general households.

BACKGROUND ART Some conventional rice polishing devices of this type are designed to apply mechanical external force in a continuous manner using pressurized air or the like underwater. For example, the
It had a structure as shown in Publication No. 52651.

That is, as shown in FIGS. 3 and 4, the hopper 1 is provided with a hopper 1 that is open at the top, and the bottom surface 2 of the hopper 1 is formed into an inverted conical shape that tapers downward. An overflow hole 3 is formed at the upper side of the hopper 1, and a connection hole 4 is formed at the lower end. A mesh-shaped valve 6 is provided at the top of the connection hole 4 to prevent the rice 5 stored in the hopper 1 from flowing out and to allow air to circulate.
is attached so that it can be opened and closed freely.

Further, a pipe 8 connected to an air pump 7 serving as an air supply device is connected to the connection hole 4. When the pipe 8 is disconnected, the connection hole 4 has a rice supply hole 9 through which the rice 5 flows out.
A faucet 11 serving as a water supply hole for supplying water 10 into the hopper 1 is provided at the top of the hopper 1 .

In the above configuration, a predetermined amount of rice 5 is put into the hopper 1, and water 10 is continuously poured from the faucet 11.
When the air pump 7 is driven, air is supplied into the hopper 1 from the connection hole 4, and as the air rises, the rice 5 inside is shaken in the water 10. In addition, the rice was circulated up and down in the hopper 1, and the rice was polished by coming into contact with each other.

Problems to be Solved by the Invention In the rice polishing device described above, an air supply device supplies air to a hopper into which a predetermined amount of rice is put together with water, and the rice in the hopper is agitated by rising airflow. It also sharpens the rice by circulating it internally.

By the way, it is well known that when rice is soaked in water, water soaks into the rice. Sugar is eluted into this water and reabsorbed in a short period of time, so it is a necessary condition for cooking delicious rice that the first polishing liquid should be drained away as soon as possible. However, it was difficult to drain the polishing liquid in a short period of time.

In addition, because it uses water, your hands get cold in winter, so there was a desire for something that could grind rice without using water.

Further, in the conventional configuration, the rice is polished using water or the like, so the device itself becomes large and it is not possible to reduce the weight.

In view of the above-mentioned problems, the present invention provides a rice polishing device which can clean polished rice using an anhydrous method and which is lightweight and compact.

Means for Solving the Problems In order to solve the above problems, the present invention provides a rice feeding hole for introducing rice, the rice feeding hole being connected tangentially at the upper part of the inner surface of the circumference, and A cylindrical rice polishing body having a large number of flexible protrusions on the inner wall surface, a cylindrical outer cylinder holding the rice polishing body, a top plate covering the upper part of the outer cylinder and having a discharge port; It consists of a cylindrical container with a bottom that fits below the outer cylinder, and is configured to forcibly discharge gas from the outlet.

Effect With the above configuration, when the internal gas is forcibly discharged from the discharge port, outside air is sucked through the rice supply hole.
If the rice grains are carried to the rice feeding hole during this suction of outside air, they will be suctioned at an accelerated rate. The accelerated rice grains enter the inner surface of the inner cylinder of the rice grinding body from a tangential direction, and come into contact with the many flexible protrusions provided on the inner wall of the rice grinding body. At this time, the rice grains roll due to surface friction or clamping of the flexible protrusions. At this time, the rice polishing body breaks down the rice bran, rice powder, dirt, etc. (hereinafter referred to as bran, etc.) adhering to the rice surface and separates it from the rice. On the other hand, rice grains weigh about 20 mg, so they descend in a spiral pattern. On the other hand, since the bran etc. have become fine and powdered, they fly out from the discharge port along with the turbulent air flow inside the polished rice body. As a result, bran etc. are separated and discharged from the surface of the rice. The rice is purified and can be made into polished rice that can be cooked without water purification.

Embodiment Hereinafter, an embodiment of the rice polishing apparatus of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, reference numeral 17 is a cylindrical rice polishing body, and a flexible protrusion 16 is provided on its inner surface. The flexible protrusion 16 is made of animal hair, soft resin such as nylon hair, rubber, a brush, or the like. The rice polishing body 17 is held by an outer cylinder 18. The inner peripheral surface of the rice feeding hole 15 is provided so as to be tangent to the surface of the flexible protrusion 16.

The upper opening of the outer cylinder 18 is covered with a top plate 19, and has a cylindrical outlet 20 near the center. The container 21 for receiving rice is fitted into the lower opening of the outer cylinder 19. This container 21 may be considered as a pot of a rice cooker. Reference numeral 22 in the figure indicates rice grains sucked through the rice feeding hole. 22a is the flexible protrusion 1
This is polished rice that has been collided with and rolled on the surface of rice to create a spiral pattern and to clean the surface of the rice bran. Reference numeral 23 indicates rice bran or the like that is separated and discharged from the discharge port.

In the above configuration, the rice grains 22 are sucked and separated from the bran 23 by forcibly discharging air from the outer cylinder 18 etc. from the discharge port 20 using a blower motor used in a vacuum cleaner or the like, or a pump. This takes advantage of the fact that when rice grains are circulated inside a cyclone, there is a difference in mass between the rice grains and the mass of the rice bran, so the rice grains fall due to inertia, and the rice bran mixes with the gas and separates. In order to promote this separation, the elastic force of the flexible protrusion 16 is used to
The entire rice grain is brought into soft contact, while the bran on the surface of the rice grain is peeled off by the impact force of the tip.

I added water for cooking to the polished rice washed in this way and compared the turbidity of the water with that of water-washed rice, but there was no difference between the two. Since no rice was used, the rice was almost completely free from bran odor, and it was confirmed that the rice polishing apparatus of the present invention could be put to practical use.

Effects of the Invention As is clear from the description of the above embodiments, the rice polishing device of the present invention accelerates rice and rolls the surface of a large number of flexible protrusions to remove rice bran, etc.
Polished rice can be cleaned with waterless washing, and since there is no cracking when the rice is submerged in water during polishing, it is possible to prevent the polished rice from being crushed, and it is also effective in saving water and preventing rice bran odor when cooking rice. In addition, the polished rice grains fall downward, and the bran generated during the polishing is led to the discharge port, so there is no need to provide a sorting mechanism to separate the rice grains and bran after the rice is polished, making the equipment smaller and lighter. can be achieved.

Furthermore, it is possible to completely eliminate the pain of soaking one's hands in cold water during the winter, and it also has the effect of allowing a large amount of rice to be polished continuously.
