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 the outer periphery of a vertical rotary tube at a to-side position, and a grinding roll and a friction roll are also attached to a do-side 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 this method had a better yield rate and could remove the germs better than the method of fertilization.

(Means for Solving the Problems) The present invention improves this point, and includes a grinding roll installed above the outer periphery of a vertical rotating cylinder, and a grain-friction roll installed below the grinding roll. This is what I did.

(Example) To explain ~Example of the present invention with drawings, 13 is the mouth 1
The polishing cylinder is made of a perforated plate having 8 holes, and the embodiment is formed into a hexagonal shape. White barrel! 3 is formed by sequentially assembling Moslem parts, and the inner presser body side is brought into contact with the inside of the outer fixing frame 19, and is fixed in advance with screws. The end of the polishing cylinder 13 is fitted into the joint between the outer fixing frame 19 and the inner presser body, the channel frame η is brought into contact with the outside of the outer fixing frame 19, and the channel frame η is fixed to the outer fixing frame 19 with the fixing bolt 23. By tightening on the outside of the channel frame η, the polishing tube 13 is fixed to the inner presser body side at the end of the channel frame η. Four outer fixed frames 19 are provided on the front, rear, left and right sides, and the outer fixed frame 19 and the outer fixed frame 1
An inner presser body 24 is brought into contact with the inner side of the middle part 9, and 1-4 is fixed with the fixing port 3 from the outside. 21 is a vertical protrusion provided on the inner presser body side.

Therefore, if you loosen the fixed pole) 23, you will get 4 pearls 01
3 can be exchanged.

A central rotary tube is provided at the center of the fixed pole 23, and a ventilation hole n that blows air in all directions is provided in the central rotary tube.

An annular gap n is formed outside L1 of the center rotation tube, and a ventilation port 31 for blowing air in all directions is provided on the center rotation portion side.

An outer rotary cylinder 3 is provided outside the annular gap n. The outer rotary cylinder is provided with vertical grooves I at predetermined intervals.

Four vertical grooves (9) are formed, and a grinding roll r and an arcuate plate part are installed every other space between the vertical grooves I and the vertical grooves. Depending on the case, a cylindrical integrated grinding roll may be used. The grinding roll 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 part.

At the lower part of the rotary cylinder 3, there are a grain friction roll g and an arc plate 3.
3 is provided every other time. The grain friction roll r may be formed with a lower part having a large diameter part and an upper part having a tapered part that gradually becomes smaller.

The side surface of the grinding roll 32, the side surface of the arc-shaped plate (and the side surface of the grain-friction roll r) become larger as they approach the outer rotary cylinder, and are tapered. Once mated.

The fitting part fits into the vertical groove, and the tapered part 36 is a grinding roll! , the arc plate portion engages with each side of the grain friction roll 37, so it can be fixed by attaching the 1F metal fitting to the outer rotary cylinder with screws.

11-The outer circumferential surface of the metal fitting 34 and the outer circumferential surface of the arc plate
Formed on a circumferential surface.

(effect) Next, we will discuss the effect.

Brown rice is introduced into the whitening room 42 and the whitening room 43, and the roll pieces 17 are
When the grinding roll lees is rotated, the rice is ground and polished while rotating between the outer circumferential surface 40 of the grinding roll lees, the inner presser side, and the longitudinal protrusions 21 of the inner presser body 24, and the whole raw bran is ground and polished at the opening 1 of the polishing tube 13.
8 and ejects to the outside.

However, since it is a grinding process, the surface becomes rough and the grain revolves around itself while rotating, so it is possible to perform rough polishing that maintains its original shape.

The refined grains go down to the milling room 42, where they are subjected to grain-by-grain friction milling by grain-by-grain friction roll correction.
Although grain-by-grain friction has the characteristic of being inefficient, since grains that have been roughly milled are rubbed together grain-by-grain, the frictional resistance is large and the grain-by-grain friction is polished more efficiently.
P buds are 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 the outer periphery of a vertical rotary tube at a position on the top side, and a grinding roll and a friction roll are also attached at a lower position. The above-mentioned known method is configured to mill brown rice that has been placed in a milling room using grinding rolls and grain-friction rolls, rather than milling under the condition of - times from beginning to end.

It was discovered that changing the method is more efficient and allows for better germ removal.

The present invention has a good score on this point, and is a rice milling roll in which a grinding roll is attached to an upper device on the outer periphery of a vertical rotating cylinder, and a grain-friction roll is attached to a lower position. Room 42. When brown rice is introduced into the polishing chamber 43, the rice polishing action is applied between the outer circumferential surface 40 of the grinding roll case and the inner presser body side and the longitudinal protrusions 21 of the inner presser body 24 to grind and polish the rice, and the generated bran is removed from the holes 18 of the polishing tube 13. Because it is ground and polished, the surface becomes rough.Since the grain revolves around its axis, it is possible to perform rough polishing while maintaining its original shape, and the coarsely polished grain is sent to the milling room As the rice descends, it is subjected to grain-by-grain friction polishing by grain-by-grain friction roll g, but grain-by-grain friction involves grain-by-grain friction between coarsely polished grains, so the frictional resistance is large, and grain-by-grain friction polishing occurs at a relatively high rate. As a result, the germ is actively removed, resulting in polished rice with beautiful skin.
