Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rice milling roll.

(Prior Art) Conventionally, a rice milling roll is known in which a grinding roll and a friction roll are attached to an upper position on the outer periphery of a vertical rotating cylinder, and a grinding roll and a friction roll are also attached to a lower position.

(Problems to be Solved by the Invention) The above-mentioned known method is configured to mill the brown rice that flows into the milling room using a grinding roll and a grain-friction roll. After various studies, it was found that the rice was milled under the same conditions from start to finish. It was discovered that changing the method was more efficient than using a method of ejaculation, and that germ removal was also better.

(Means for solving the problem) The present invention improves this point, and includes a milling roll in which a grinding roll is mounted above the outer periphery of a vertical rotating cylinder, and a grain-friction roll is mounted below the grinding roll. This is what I did.

(Example) An example of the present invention will be described with reference to the drawings.
Reference numeral 3 designates a polishing cylinder made of a perforated plate having holes 18, and in the embodiment, it is formed into an octagonal shape. The polishing cylinder 13 is formed by sequentially assembling four pieces, and the outer fixed frame 19
The inner presser body 20 is brought into contact with the inner side of the holder and fixed in advance with screws. The end of the polishing tube 13 is attached to the outer fixing frame 1
9 and the inner presser body 20, the channel frame 22 is brought into contact with the outer side of the outer fixing frame 19, and the channel frame 22 is tightened to the outer side of the outer fixing frame 19 with the fixing bolts 23. The polishing cylinder 13 is fixed to the inner presser body 20 at the end thereof. Four outer fixing frames 19 are provided in the front, rear, left, and right, and an inner presser body 24 is abutted on the inner side between the outer fixing frames 19 and fixed from the outside with fixing bolts 25. 21 is the inner presser body 20
It is a vertical ridge provided on the ridge.

Therefore, by loosening the fixing bolt 23, the four polishing cylinders 13 can be replaced.

A center rotating tube 26 is provided at the center of the fixing bolt 23, and a ventilation port 27 for blowing air in all directions is provided in the center rotating tube 26. An annular gap 28 is formed on the outer periphery of the central rotating cylinder 26, and ventilation holes 31 are provided in the central rotating cylinder 26 to blow air in all directions. An outer rotary cylinder 29 is provided outside the annular gap 28. The outer rotary cylinder 29 is provided with vertical grooves 30 at predetermined intervals. Four vertical grooves 30 are formed, and a grinding roll piece 32 and an arc plate 33 are formed between the vertical grooves 30.
are installed every other time. Depending on the case, a cylindrical integrated grinding roll may be used. The grinding roll 32 may have a tapered portion having a large diameter portion at the bottom and a tapered portion having a gradually smaller diameter at the upper portion.

At the lower part of the rotary cylinder 29, a grain friction roll 3 is installed.
7 and arcuate plates 33 are provided every other time. The grain friction roll 37 may be formed with a lower part having a large diameter part and an upper part having a tapered part having a gradually smaller diameter.

The side surface of the grinding roll 32, the side surface of the arc-shaped plate 33, and the side surface of the grain friction roll 37 become larger as they approach the outer rotary cylinder 29, and are tapered.
When the stopper 34 is fitted into the longitudinal groove 30 from the outside, its fitting part 35 fits into the longitudinal groove 30, and its tapered part 36 is connected to the grinding roll 32, the arcuate plate 33,
Since it engages with each side of the friction roll piece 37,
It can be fixed by fixing the stopper 34 to the outer rotary cylinder 29 with a screw.

The outer circumferential surface 38 of the stopper 34 and the outer circumferential surface 39 of the arc-shaped plate 33 are formed into the same circumferential surface.

(effect) Next, we will discuss the effect.

When brown rice is introduced into the whitening chamber 42 and the whitening chamber 43 and the roll piece 17 is rotated, it rotates between the outer peripheral surface 40 of the grinding roll 32 and the longitudinal ridges 21 of the inner presser 20 and the inner presser 24. The rice is polished and polished as it revolves, and the generated bran is ejected to the outside through the holes 18 of the polishing cylinder 13. However, since it is a grinding process, the surface becomes rough, and since the grain revolves while rotating on its axis, it is possible to polish the grain to its original shape while maintaining its original shape.

When the grains that have been milled in their original form go down to the milling room 42, they are subjected to grain-by-grain friction grinding by the grain-by-grain friction roll 37. Although grain-by-grain friction has the characteristic of inefficiency, Since the rice is rubbed grain by grain, the frictional resistance is large, and the rice is polished grain by grain in a relatively efficient manner.The germ is also actively removed, resulting in polished rice with beautiful skin.

(Effects) Conventionally, a rice milling roll is known in which a grinding roll and a friction roll are attached to an upper position on the outer periphery of a vertical rotating cylinder, and a grinding roll and a friction roll are also attached to a lower position. The above-mentioned known method is configured to mill the brown rice that flows into the milling room using grinding rolls and grain-friction rolls. After various researches, I found that:
It was discovered that changing the conditions is more efficient than refining under the same conditions from beginning to end, and the germs can be removed better.

The present invention has improved this point, and the polishing roll is equipped with a grinding roll installed above the outer periphery of the vertical rotary cylinder, and a grain-friction roll installed below the polishing roll. 42,
When brown rice is introduced into the whitening chamber 43, the grinding roll 32
The outer circumferential surface 40 of the inner presser body 20 and the inner presser body 2
The rice polishing action works between the longitudinal protrusions 21 of 4 and the rice is polished and polished, and the generated bran is ejected to the outside through the holes 18 of the polishing tube 13. Since it is a grinding process, the surface becomes rough and the grain rotates on its axis. Since the grains rotate while rotating, grains can be milled in their original shape while maintaining their original shape.
The rice undergoes grain-by-grain polishing as described in step 7. Grain-by-grain friction is the process by which grains that have been polished in their original form are rubbed against each other grain by grain, so the frictional resistance is large and the rice is polished grain by grain in a relatively efficient manner, and the germ is also removed. It is carried out vigorously and has the effect of producing polished rice with beautiful skin.
