Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a germ rice milling machine for household use, which has a low rice yield and has the function of producing ordinary milled rice in addition to germ rice.

``Prior art and its problems'' There are various types of home rice milling machines on the market, but these machines mill the rice using milling rolls that rotate at high speed, so the rice comes into strong irregular contact with each other in multiple directions. Moreover, since this rice has heat, breaking it results in a high percentage of rice, and the germ part also falls off, making it extremely difficult to make germ rice.

On the other hand, rice germ contains vitamin B1. B2, B6, B12
It is known to contain many vitamins such as , E, and D, as well as high-quality protein and fat. Rice that retains its germ, or germ rice, is a highly balanced nutritional food and an ideal staple food. In order to provide a germ rice milling machine that can easily produce such germ rice at home, the inventor of the present invention has conducted extensive research and found that in order to reduce the percentage of broken rice and leave the germ part, Avoid violent contact between rice grains due to irregularities in multiple directions, and gently control the speed of contact between rice grains, rice and stirring blades, or rice and visitor equipment to polish the rice. In the process, the rice bran can be polished efficiently and in a short time. The present invention was achieved based on the discovery that it is important to separate the rice into two parts, and to always grind the rice with its long sleeves upright, that is, to avoid rubbing the germ-bearing part as much as possible.

``Means for Solving the Problems'' Namely, the present invention provides a rice container body in which a net container having a mesh and an abrasive surface is spaced apart from the rice container body to separate rice bran while polishing. A flow path for bran and air is formed between the mesh container and a stirring grinding rice blade that grinds the rice and simultaneously pushes it downward by friction with a polishing surface formed on a rotary blade. The main purpose of this document is to provide the following information.

The effect of the present invention is due to the fact that a net container with an abrasive surface is placed inside the visitor device, giving it a double structure, and the bran is efficiently removed in a short time by centrifugal force. It is thought that rice can be milled, and therefore the heat generation of the rice is suppressed to a low level, and as a result, the percentage of rice in the frame is reduced, and germ rice can be efficiently milled.

"Example" Next, embodiments of the present invention will be described with reference to the drawings.

A rice container main body (main container) 2 is screwed into a power unit l containing a motor, and is detachably connected to a drive shaft 3 of the motor and a rotating shaft 4 of the main container 2. In the above-mentioned embodiment, the coupling means is achieved by engaging concave and convex portions 18 and 17 formed on the opposing surfaces of the drive shaft 3 and the rotary shaft 4 so as to engage with each other.

Inside the main container 2, mesh containers 6 are arranged at intervals. This mesh container is formed into a cylindrical shape with an open upper end from a punched wire mesh having a mesh and a polished surface.

Inside the net container 6, there is a stirring and polishing rice blade 7 having four blades connected in series.
It is fixed to the upper end of the rotating shaft 4. Fixed is stirring polished rice blade 7
This is done by fitting a hole formed in the blade connecting portion into the tip of the rotating shaft, and screwing and tightening the nut 29 onto the rotating shaft from above.

The stirring and grinding rice blade 7 has a configuration in which four horn-shaped blades are connected at the bottom thereof, and is formed so that the rice can be pressed downward with the horn-shaped recess. The surface of this agitating rice blade is made of a punched wire mesh with an uneven shape, so by rotating the shaft 4, the uneven surface on the front and back rubs the rice and presses it downward. Clogging of the polishing surface due to bran during polishing is effectively prevented.

Since the mesh container is formed from a punched wire mesh, the rice pressed into the mesh container is polished, the resulting bran is passed through, and the rice bran is discharged from the flow path between the main container and the mesh container. A spacer 12 is interposed between the net container and the zero main container which is accommodated in the rice bran bag ll through the wire, and the spacer 12 holds the net container 3 and the main container 2 apart from each other. . In the above embodiment, the spacers are provided at the upper and lower parts of the inner peripheral surface of the main body container, and are constructed by protruding four protrusions from each part at equal intervals on the same plane. . A bearing 2B is fixed to the center of the bottom of the net container 9, thereby rotatably supporting the rotating shaft 4.

A lid 23 is removably fitted on the top surface of the main container, and the lid 23 is open at the center, and there is a short cylindrical dish-shaped knob 24 with an air inlet 19 bored in the center of the opening. are removably fitted.

A bran discharge section 13 is formed at the upper end of the power section 1 through a partition 30, and a propeller 15, 15' is attached to the drive shaft 3 which passes through the bran discharge section 13 through the partition 30. ing. This serves to smoothly discharge the bran produced by grinding the rice in the mesh container through the flow path between the main container 2 and the mesh container 6.
In the figure, numeral 14 denotes a protective tube that is tightly fitted to the rotating shaft, and is used to prevent the generated bran from coming into contact with the rotating shaft.

A semicircular fixture 32 is connected to the bottom end of the rice milling machine.
This fixture 32 has an open bottom and an air outflow hole 3 at the lower end side.
A rice bran bag container 38 having a shape of 3 is placed thereon. The upper end and main body of the rice bran bag container 36 are connected by fitting and can be separated from each other. Note that a net 40 is stretched over the air outflow hole 33.

The rice bran bag container 3B has a transparent lid 3 having an arcuate curved surface.
5 is fixed so as to be able to slide in an arc with a shaft 41 as a fulcrum. Inside the rice bran bag container 3θ is a bellows-shaped rice bran bag 11.
is accommodated, and a fitting recess formed on the frame plate 39 at the tip of the rice bran bag and a fitting convex portion formed on the back side of the frame plate 40 at the tip of the rice bran bag container lid are removably connected. As shown in FIGS. 1 and 2, the bran discharge port and the bran bag are connected by connecting a frame plate 42 formed in the bran discharge port with an opening at the center and a frame plate 40 at the end of the lid body with an opening in the center to connect the bran discharge port with the bran passing hole. The rice bran bag 11, which is fixed by sandwiching the frame plates at the upper end with the spring clamps 37, has an upper part made of a vinyl bellows that expands and contracts together with the lid body 35, and is connected to the vinyl bellows. Since the main body is made of paper made of an air-permeable material used in electric vacuum cleaners, only the bran is captured in the bran bag 11, and the air passes through the bran bag and exits from the discharge port 33 of the bran container 36. It is discharged.

A knob 27 for setting the rotational speed of the motor is provided on the front face of the power unit 1. The rotational speed of the motor is displayed at the top of this knob, and 'fast' is displayed at the bottom. This knob can move freely in the horizontal direction, so you can move the knob depending on the desired rice polishing level, which is closer to brown rice or closer to white rice, focusing on embryonic rice. A suitable rotation speed can be selected as appropriate.

Below the knob for setting the rotational speed, a dial 28 is provided, which is similar to that used when milling rice. At the top of the dial,
Five lines are displayed in different colors for each amount of rice to be polished. The lines of the five trees are 1/2, 1/3, 1, 1, respectively.
5, 2, germ rice is 1, and 1/3 is closer to brown rice
, 1/2 means 1.5, 2, which is closer to white rice. For example, when germ-polishing 3-go rice, germ-polishing rice on the number 3 line is yellow, and rice that is more similar to brown rice is yellow. For blue, green, and more polished rice, if you turn the dial to the red and white numbers, the motor will rotate for the appropriate time and the rice will be polished.

In this manner, in the above embodiment, the rotational speed control and the rotation time control of the motor are performed simultaneously and in conjunction with each other.

Generally, when milling rice, the rotation speed and rotation time to achieve a predetermined level of polishing will vary depending on the amount of moisture and the type of brown rice, such as new rice or old rice. Therefore, if the above embodiment is used, the user can set the optimal conditions according to the type of brown rice to be used and the desired germ polishing level, etc. within the color-coded width ranges described above. will be possible.

[Operation] Next, the operation of the present invention configured as described above will be explained with reference to the drawings.

First, the knob 27 is moved to the position where the color of the desired rice polishing level is displayed to set the number of revolutions. Next, depending on the degree of rice polishing and the amount of brown rice to be polished, the dial 28 is moved to the position corresponding to the color displayed, and the rice polishing time is set. Then, add the specified amount of brown rice and turn on the switch. As the motor rotates, the stirring and polishing rice blades 7 rotate slowly, rubbing the rice against the polishing surface and pressing it downward. The rice pressed by the stirring and grinding rice blades 7 is lifted from the bottom of the mesh container to the top surface while being rubbed by the mesh surface, as shown by the arrow in FIG. , to be studied and suppressed. This operation is repeated for a predetermined period of time.

On the other hand, as the rotating shaft rotates, the propeller 1 of the bran discharger 13
5.15' also rotates, sucking air through the air inlet lθ at the top of the rice milling machine as shown by the dashed arrow in Figure 1, passing through the rice in the net container B, and releasing it along with the bran into the main container 2 and the net container 6. The air is discharged into the rice bran bag 11 through the passage between the rice bran and the rice bran bag 11, and the air is discharged from the discharge port 33 of the wave number container 36.In this way, the air during rice milling constantly passes through the rice container, and the rice heated by polishing is discharged from the rice bran bag 11. Because of the cooling, crushing of the rice reduces the rice rate and prevents the loss of germ.Using the above rice milling machine, the rotation rate is 600 r.
According to the experimental results of germ milling rice for 8 minutes at pm, germ milled rice with a germ retention rate of 88% was obtained, and no broken rice was produced. This is an extremely remarkable effect that is not seen in conventional germ rice milling machines.

It goes without saying that in order to mill rice using the rice milling machine of the present invention, the rotational speed of the rice milling machine can be increased.

[Effects of the Invention] As described above, according to the present invention, bran is separated by centrifugal force while the brown rice is rubbed by the stirring and polished rice blade, pressed downward, and rubbed by the mesh surface, so that the bran removal efficiency is improved. This significantly improves the rice polishing rate and allows rice to be polished in a short time.As a result, the degree of heating of the rice is lowered, which causes the germ to detach, significantly increasing the germ survival rate and allowing rice to be polished to the desired germ polishing degree. . In addition, since an air flow path is formed between the net container and the main container, the air flowing into the milled rice container can cool the heated rice, thereby reducing the rice crushing rate. To reduce the amount of bran and to easily discharge the generated bran in a short time.
