Abstract

PURPOSE: To clean a rice without using water and without crushing, by providing a cylindrical rice polishing body with a rice feed hole on its tangent, providing the inside wall thereof with many soft projecting bodies and forcibly discharging a gas from a discharge port. CONSTITUTION: The rice polishing machine for polished rice to be used in general homes is constituted by providing the inside surface of the cylindrical rice polishing body 17 with the soft projecting bodies 16, holding the rice polishing body 17 with an outside cylinder 18 and forming the inner peripheral surface of the rice feed hole 15 so as to be made tangent to the surface of the soft projecting bodies 16. When the air of the outside cylinder 18 or the like is forcibly discharged from the discharge port 20 by a blower motor, pump or the like, rice grains are sucked and are separated from bran or the like but since there is a difference in the mass between the rice grains and the bran or the like, the rice grains falls by inertia force and the bran or the like is entrained in the gas. If the bran or the like is removed by accelerating the rice in such a manner and rolling the rice on the surfaces of the soft projecting bodies, the polished rice may be cleaned without water washing. Since there are no cracks at the time of the rice polishing, the crushing of the rice is prevented.

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 OF THE INVENTION Conventional rice polishing apparatuses of this type include those in which mechanical external force is applied in a continuous manner using pressurized air or the like underwater. For example, the structure was as shown in Japanese Patent Publication No. 68-52651.

That is, as shown in FIGS. 3 and 4, a hopper 1 with an open top is provided, and a bottom surface 2 of the hopper 1 is shaped like an inverted cone and 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. The rice 6 stored in the hopper 1 is located above the connection hole 4.
A mesh-shaped valve 6 that prevents the outflow of air and allows air to flow is attached so as to be openable and closable.

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 connecting hole 4 has an unsupplied hole 9 through which the rice 6 flows out.

A faucet 11 serving as a water supply hole for supplying water 1o into the hopper 1 is provided at the upper part of the hopper 1.

In the above configuration, a predetermined amount of rice 6 is placed in the hopper 1, water 10 is continuously supplied from the faucet 11 to the extent that it flows out from the overflow hole 3, and when the air pump 7 is driven, the connection hole 4 Air was supplied into the hopper 1, and as the air rose, the rice 6 inside was stirred in 1 liter of water, which was also circulated up and down within the hopper 1, and the rice was polished by coming into contact with each other.

Problems to be Solved by the Invention The rice polishing device described above supplies air from an air supply device to a hopper into which a predetermined amount of rice is put together with water, and the rice in the hopper is agitated by the rising air flow. 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 to drain the -th polishing liquid as soon as possible, but with the rice polishing device mentioned above, , It was a pain to drain the sharpening fluid 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.

The present invention takes into account the above-mentioned conventional problems and provides a rice polishing device that can clean polished rice with waterless washing and can polish rice without getting hands wet in winter.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a rice feeding hole for introducing rice, and a plurality of holes in which the rice feeding holes are connected on a tangent to the inner surface of the circumference, and a large number of rice feeding holes are provided. A cylindrical rice polishing body having a flexible protrusion 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, and the outer cylinder. It consists of a cylindrical container with a bottom that fits at the bottom, and is configured to forcibly exhaust gas through the outlet.

Operation With the above configuration, when the internal gas is forcibly discharged through the discharge port, outside air is sucked through the rice feeding 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 cylindrical inner surface of the polished rice body in a tangential direction, and come into contact with the many flexible protrusions provided on the inner wall of the polished rice body. At this time, the rice grains are
Rolls due to surface friction or clamping of flexible protrusions. At this time, the rice bran, rice flour, dirt, etc. (hereinafter referred to as bran, etc.) adhering to the surface of the rice become finer and separate from the rice. On the other hand, rice grains have a weight of about 20m9, so they descend in a spiral pattern. On the other hand, since the bran etc. are finely divided and powdered, they fly out of the discharge port along with the turbulence inside the grinding body. As a result, rice bran and the like 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.

EXAMPLE Below, an example of the rice polishing apparatus of the present invention is shown in FIGS. 1 and 2.
This will be explained with the help of a diagram.

In the figure, 17 is a cylindrical rice polishing body, and a flexible protrusion 16 is provided on its inner surface. This flexible protrusion 1
6 is made of animal hair, soft resin such as nylon hair, rubber, brush, etc. The rice polishing body 17 is held by an outer cylinder 18. The inner peripheral surface of the rice feeding hole 16 is provided so as to be tangential 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 2o 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. 2 in the diagram
2 is a rice grain that is sucked through the rice feeding hole. 22a is polished rice that collides with the flexible protrusion 16 and rolls, forming a spiral pattern and cleaning 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 and the like by forcibly discharging air from the outer cylinder 18 etc. from the discharge port 2o 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 between the mass of the rice grains and the mass of the bran, etc., so the rice grains fall due to inertia, and the bran etc. are mixed with gas and separated. . In order to promote this separation, the elastic force of the flexible protrusion 160 is used to bring the entire rice grain 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 and the like. In addition to being able to clean the polished rice, there are no cracks when the rice is submerged in water during polishing, so the milled rice can be prevented from being crushed, water can be saved, and rice bran odor can be prevented when the rice is cooked.

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.
