Description

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

(Prior art) Conventionally, a grinding roll piece and a friction roll piece were installed in a symmetrically protruding position above the outer periphery of an outer rotating cylinder, and a grinding roll piece and a friction roll piece were similarly protruded symmetrically in a lower position. Those that are installed in this manner are well known.

(Problems to be Solved by the Invention) The above-mentioned known method is configured to grind and polish the brown rice that has entered the milling room while stirring it with friction roll pieces, but the conventional method does not grind and polish the rice from beginning to end. As a result, the surface of polished rice becomes coarse.

Therefore, a problem arose in that a large amount of fine powder adhered to the surface.

(Means for solving the problem) The present invention improves this point, and the grinding roll pieces 32, 32 are provided at positions above the outer periphery of the outer rotary cylinder 29.
The grinding roll piece 3 is attached so as to protrude symmetrically.
At the lower position of 2, friction roll pieces 37, 37 are attached in a symmetrically protruding manner.

(Example) An example of the present invention will be described with reference to the drawings.
Reference numeral 3 denotes a polished cylinder made of a perforated plate with 18 holes, and in the embodiment, it is formed into an octagonal shape. The polishing tube 13 is formed by sequentially assembling four pieces, and the inner presser body 20 is brought into contact with the inside of the outer fixing frame 19 and fixed in advance with screws.The end of the polishing tube 13 is attached to the outer fixing frame 19. The channel frame 22 is fitted into the joint part of the inner presser body 20, and the channel frame 22 is brought into contact with the outside of the outer fixing frame 19, and the channel frame 22 is fixed to the outer fixing frame 1 using the fixing bolts 23.
By tightening the outside of the channel frame 2
The end portion of 2 is fixed to the inner presser body 20 of the polishing cylinder 13. Four outer fixing frames 19 are provided on the front, rear, left and right sides,
An inner presser body 24 is brought into contact with the inner side between the outer fixing frames 19 and the outer fixing frame 19, and is fixed from the outside with fixing bolts 25. 21 is a vertical protrusion provided on the inner presser body 20.

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 is provided in the center rotating tube 26 to blow air in all directions. An annular gap 28 is formed on the outer periphery of the central rotating cylinder 26, and an outer rotating 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 grinding roll pieces 32 and arcuate plates 33 are attached every other time between the vertical grooves 30. The grinding roll piece 32 is attached to the outer rotating cylinder 29
Friction roll pieces 37 and arcuate plates 33 are provided at alternate positions at the lower position. The side surfaces of the grinding roll piece 32, the arcuate plate 33, and the friction roll piece 37 become larger as they approach the outer rotary cylinder 29, and are tapered. When the stopper 34 is fitted into the vertical groove 30 from the outside,
The fitting part 35 fits into the vertical groove 30, and the tapered part 36 engages with each side surface of the grinding roll piece 32, the arc plate 33, and the friction roll piece 37, so the stopper 34 is rotated outward by the screw. It can be fixed by attaching it to the tube 29.

The outer circumferential surface 38 of the stopper 34 and the outer circumferential surface 39 of the arc-shaped plate 33 are formed on the same circumferential surface, but the outer circumferential surface 40 of the roll piece protrudes more than that.

(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, the grinding roll pieces 32 and 3
The rice polishing action of the outer circumferential surface 40 of No. 2 and the longitudinal protrusions 21 of the inner presser 20 and the inner presser 24 works to grind and polish the rice, and the surface is polished to a rough state. It passes through and gushes out to the outside.

When the white rice in the whitening room 42 and the whitening room 43 descends,
Frictional polishing is performed by friction roll pieces 37, and since the surface of the rice is polished to a rough state, the rice is efficiently stirred and rubbed grain by grain, resulting in polished rice with a beautiful skin surface.

As a result, the rice is polished differently from milling using only the grinding roll pieces 32 and milling using only the friction roll pieces 37.

Therefore, the grinding roll piece 32 and the friction roll piece 3
7 have different degrees of wear, but the present invention can be easily replaced by removing the stopper 34.

(Effects) Conventionally, a grinding roll piece and a friction roll piece were installed in a symmetrically protruding position above the outer periphery of the outer rotating cylinder, and a grinding roll piece and a friction roll piece were similarly protruded symmetrically in a lower position. Those installed using the same method are known.

The above-mentioned known method is configured to grind and polish the brown rice that has entered the milling chamber while stirring it with friction roll pieces, but the conventional method involves grinding and polishing from beginning to end, so the surface of the polished rice is Becomes coarse.

Therefore, a problem arose in that a large amount of fine powder adhered to the surface.

However, in the present invention, the grinding roll pieces 32, 32 are mounted in a symmetrically protruding position above the outer periphery of the outer rotating cylinder 29, and the friction roll pieces 37, 37 are mounted symmetrically below the grinding roll piece 32. Since it is a milled roll attached to the grinding roll piece 32, when the roll piece 17 is rotated, the grinding roll piece 32,
The rice is ground and polished between the outer circumferential surface 40 of 32 and the vertical ridges 21 of the inner presser body 20 and the inner presser body 24 to have a rough surface. However, since the surface of the rice is polished to a rough surface, the rice is efficiently stirred and abraded grain by grain, which has the effect of producing polished rice with a beautiful skin surface.
