Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice polishing machine for polished rice that is used in general households and is capable of cooking polished rice with waterless washing.

BACKGROUND OF THE INVENTION Conventional rice polishing machines of this type include those that are capable of continuously polishing and polishing brown rice.

An example thereof will be explained with reference to FIG.

In the figure, 21 is a brown rice tank, and a grain feeding chamber 22, a rice polishing chamber 23, and a rice polishing chamber 24 are successively connected to each other through an opening at the bottom of the tank. 25 is a rice polishing rotor rotated by a drive shaft 26. Further, the rice polishing chambers 24 are each provided with a rice polishing body 29 shaped like a mold wheel for polishing polished rice. Reference numeral 30 denotes a polished rice outlet provided in the rice polishing chamber 24, and a pressure regulating valve 31 that can be closed is attached thereto. 32 is a cylindrical body, and the rice polishing chamber 23. Rice research room 2
It covers 4.

Put brown rice into the brown rice tank 21 of the rice polishing machine configured as above,
When the rotating shaft 25 is rotated by the drive shaft 26, the brown rice is transferred downward through the grain feeding chamber 22 by the conveying spiral 27 and is transferred to the rice milling chamber 23.
The brown rice enters the rice milling process and is polished by the friction caused by the stirring of the rice polishing trochanter 28 and the mutual frictional action of the brown rice. The milled rice flows into the rice polishing chamber 24 and is polished by the rice polishing body 29, and then the pressure regulating valve 31 is pushed open from the polished rice outlet 30 and flows out from the outlet gutter 34 into the container.

Problems to be Solved by the Invention The rice polishing machine described above sequentially polishes brown rice and polishes polished rice. As the rice body 29 rotates, the back of the mold wheel-shaped teeth forcefully presses the polished rice against the side wall surface of the rice polishing chamber 24 to perform a rice polishing action, and this pressing force also creates frictional force between the polished rice. This increases the rice polishing effect. In addition, a pressure regulating valve 3 attached to a polished rice outlet 30 provided in the rice polishing room 24
1 also increases the pressing force and contributes to the rice polishing action.

This method of polishing rice using pressing force has an excellent rice polishing effect, but in order to obtain the pressing force, the rice polishing body 29 has to be highly rigid, and the pressing force during rice polishing is This may cause the polished rice to break and the incidence of broken rice to increase. In addition, since the rice is polished using pressing force, the surface of the polished rice will be worn more, which may increase the incidence of bran and rice powder, and the moisture content of the polished rice will decrease due to the heat generated by the friction between the polished rice. There were problems such as the possibility that

In view of the above problems, the present invention aims to solve various problems caused by polishing rice using pressing force.

Means for Solving the Problems In order to solve the above problems, the present invention provides a hopper for charging rice, and a cylindrical polished rice made of a thin plate connected horizontally to the hopper and having a large number of small holes. and an outer casing that covers a polishing body rotatably housed inside the rice polishing body, and a lower opening of the hopper connected to the polishing body is connected to a side surface of the polishing body in the rotation direction of the polishing body. It was formed in

Operation With the above configuration, polished rice flows from the hopper into the rice polishing body by gravity and the suction force generated by the rotation of the polishing body.

Then, due to the transfer between the flexible protrusions and the rice polishing body provided at intervals on the surface of the rotating polishing body, and the transfer due to the clamping between the flexible protrusions and the rice polishing body, the particles adhere to the surface of the polished rice. It is possible to quickly remove rice bran, etc., and make it into polished rice that can be cooked without washing water.In addition, by flowing the rice from the side in the rotational direction of the polishing body, the lower opening of the rice polishing chamber hopper can be used as a rice polishing chamber. There is no need to place the rice above the rice bowl, and the main body can be made smaller or the hopper can be made larger to store a large amount of rice. In addition, since the polished rice is sucked into the rice polishing body by the suction force generated by the rotation of the polishing body, the polished rice is thrown up by the flexible projections provided on the surface of the polishing body, and the polished rice does not enter the rice polishing body. Not that there isn't.

EXAMPLE Hereinafter, an example of the rice polishing machine of the present invention will be explained based on FIGS. 1 to 5.

In the figure, 1 is the main body, and the rice input port 2 is located at the top of the front.
It has a hopper 3 inside it. A measuring chamber 4 is provided in communication with the opening at the bottom of the hopper 3, and below it, a rice polishing chamber hopper 5 and a rice polishing chamber 6 are successively connected. The rice polishing chamber 6 is formed by a case 7 and a case lid 8. A shaft 10 of an electric motor 9 passes through the upper part of the rice polishing chamber 6 from the rear, and a power transmission bottle 11 is press-fitted into the shaft 1o, through which a polishing body 12 is rotationally driven. Surrounding the polishing body 12 is a polishing body 13 formed into a cylindrical thin plate with a large number of small holes. The small holes are large enough that polished rice cannot pass through. 14 is a flour receiving tray, and rice polishing room 6
A brush 15 made of nylon fiber, boar hair, etc. is spirally implanted on the outer periphery of the polishing body 12 which is detachably inserted into the lower part, and a brush 15 made of nylon fiber, pig hair, etc. is spirally implanted between the tip of the brush 15 and the inner surface of the polishing body 14. The gap is large enough to hold rice grains without crushing them. The case lid 8 has a non-discharge port 8a. A rice tray 17 is set below the chute 16, and polished polished rice is stored therein. The rice polishing chamber hopper 5 is provided in the case 7 of the rice polishing chamber 6, and its lower opening 5a is formed on the side surface in the rotation direction of the polishing body 12.

Next, the operation of the rice polishing machine having the above configuration will be explained.

Rice put in through the rice input port 2 is temporarily stored in a hopper 3, and by operating a switch, the volume is measured in a measuring chamber 4 and guided to a hopper 5 in the rice polishing chamber. Next, the rice is processed using the rice grinder hopper 5.
The rice is guided to the grinding body 13 which communicates with the lower opening. At this time, since the lower opening of the rice polishing chamber hopper 5 is formed on the side surface in the rotating direction of the polishing body 12, the rice is guided into the rice polishing body 13 from the side by gravity and the suction force generated by the rotation of the polishing body 12. The rice in the rice polishing chamber hopper 5 is further pushed forward by the rotation of the polishing body 12, and the rice in the rice polishing chamber hopper 5 is quickly introduced into the rice polishing body 13. Rice entering the lower opening of the rice polishing chamber hopper 5 is pressed against the rice polishing body 13 on the outer periphery by the rotation of the polishing body 12 and is polished. The rice pushed out to the tip of the polishing body 12 is
The rice is guided to the rice tray 17 through the undischarged port 8a of the case lid 8 and the chute 16. The rice bran and the like removed by the rice polishing body 13 fall downward and are stored in the flour receiving tray 14.

Effects of the Invention As described above, the rice polishing machine of the present invention includes a rotatable polishing body inside a cylindrical rice polishing body having a large number of small holes, and a large number of flexible protrusions on the surface of the polishing body. The polished rice is rolled between the flexible protrusion and the rice polishing body, and the rice is pinched and transferred between the flexible protrusion and the inner surface of the rice polishing body to remove bran etc. from the polished rice. In addition to being able to clean polished rice with waterless washing, by forming the lower opening of the rice polishing chamber hopper on the side surface in the rotational direction of the polishing body, the rice polishing chamber hopper accommodates the rice volumetrically measured in the measuring chamber. There is no need to place the lower opening at a higher position than the rice grinding chamber (this allows the hopper of the main body to be enlarged, increasing the amount of rice that can be stored, or providing a small rice grinding machine). In addition, the polished rice flows into the rice grinder by gravity and the suction force generated by the rotation of the polisher, so there is no splashing of the polished rice, it is guided smoothly into the rice grinder, and the rice is polished quickly. It will be done.
