この発明は米や麦などの穀物の新規な搗精方法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a novel method for milling grains such as rice and wheat.
従来、情穀方法としては、際擦式と研削式との２方式が
一般に実施さハていど》。摩擦式は積白室内で、表面に
突条を有する精白ロー）Ｖを回転させ、穀粒相互間に作
用する接触圧力と接触摩擦力とによって、表面の糠層を
引き裂くように取り除く方式であり、また研削式は精白
室内で金剛砂鰻などの研削ロールを回転させ、金剛砂粒
子の尖った角で穀粒表面の糠層を削り取る方式である。Conventionally, two methods have been generally used for grain grinding: the rubbing method and the grinding method. The friction method is a method in which a milling row (V) with protrusions on the surface is rotated in a whitening room, and the bran layer on the surface is torn and removed by the contact pressure and contact friction that act between the grains. The grinding method is a method in which a grinding roll such as Kongo sand eel is rotated in a milling room, and the bran layer on the surface of the grain is scraped off with the sharp corners of the Kongo sand particles.
ところが、摩擦式の場合には、高い圧力をかけることが

、食味を低下させる原因になるという欠点があり、また
反面、穀粒表面を部分的にＴｆ ｊ７ζに削っていく為
、表面全体としては搗積効率が悪く、作業に長時間を要
したり、発熱が多いなどの欠点がある。However, in the case of the friction type, it is essential to apply high pressure, and this pressure has the disadvantage of easily causing cracked rice and shattering of weak internal grains. In the initial stage, the grain surface is smooth, resulting in poor working efficiency, and the pounding accuracy cannot be increased beyond a certain level, so it cannot be used, for example, for polishing sake-brewing rice. On the other hand, in the case of the grinding method, the grain surface is ground down with the sharp edges of the diamond sand particles, resulting in a thin and deep I'7ζ that looks like a cat's claw.
This has the disadvantage that these grooves reach the inner part of the grain and cause damage to the grain, reducing the taste.On the other hand, because the grain surface is partially scraped to Tf The surface as a whole has disadvantages such as poor sanding efficiency, long working hours, and high heat generation.

精埋論に基すいた全く新しい精穀方法を提共せんとする
もので、先端が鋭角の刃体で殼粒の表面をリンゴの皮を

ものである。The present invention addresses the above points and aims to provide a completely new grain milling method based on the theory of milling and burying grains, which is different from the conventional grain processing method. The surface is peeled off thinly, like peeling the skin of an apple, to allow the polishing process to proceed.

穀粒の表面を薄く広く剥ぎ１１゛ノるようにして搗精を
進行させることにある。The technical means of the grain milling method of the present invention is that inside a fixed milling barrel, a ceramic blade rotates a milling roll fixed to the peripheral wall surface, and the blade is inserted into the gap between the milling barrel and the milling roll. Hit? The purpose of this method is to co-feed the grains and to advance the milling process by peeling the surface of the grains thinly and widely using a blade with an acutely pointed top so that the surface of the grains is 11 degrees wide.

等に削られるようになる。In the scraping-type grain grinding method of the present invention, the milling roll is rotated and transmitted in the whitening outer cylinder, so that the blade collides with the grains that are internally fed into the gap between the two, and the blade sharply points. The surface of the grain is scraped off with a scraper. Blade 1 at this time
The peeling action by 'C is achieved because the blade is long in the longitudinal direction and has a sharp apex, and is fixed in a prone position slightly protruding from the peripheral wall of the cleaning roll, so that the surface of the grain is thin,
It has a relatively large area and can be cut into a so-called thin-sided shape. In addition, during peeling, the surface of the grain is scratched with a sharp blade, so a large rotational force is applied to the grain for this purpose, and a strong stirring action occurs between the grains during the peeling process. . Then, as a result of the peeling action progressing while being subjected to this stirring action, the entire surface of all grains is scraped evenly and evenly.

FIG. 1 is a diagram showing the principle of peeling and milling, where (1) shows the blade, (2) shows the whitening roll, and the person shows the ground grains. The blade body (1) is made of ceramic, the top (3) has an acute angle, 1
It is shaped at 0 to 90 degrees. Especially for stacking rice, 5
A suitable angle is 0 to 80 degrees. Also, the top (3) needs to be sharply pointed, and the radius of the top tip (edge) is 5
It is preferable to set it to 0 micron or less. Such sharp edges can be achieved by using ceramics, whereas ordinary metals wear out quickly with use, making it impossible to maintain sharp edges. The blade body (1) is fixed to the whitening roll (2) in a semi-buried manner, and the upper part of the blade body (1) protrudes from the periphery of the row/l/(2). Blade (1
), the blade body (1) collides with the milled grains (4) which are co-fed in the gap between the milling barrel (2) and the milling outer cylinder (4), and the blade The sharp edge of the blade (1) scrapes the skin of the grain in a thin and relatively wide area, 6. This peeling action of the blade (1) is similar to that of a horsefly. This is completely different from the foot friction method or the grinding method.

ある。That is, in the friction method, grains are peeled by the frictional action of contact with each other, and in the grinding method, grains are shaved off at the sharp corners of the diamond sand particles.In contrast, the present invention The blade (1) is used to remove the skin from grains (like peeling the skin with a knife).
Since the surface of the N grain is scraped thinly, the peeling force of the present invention can be efficiently peeled without creating deep grooves on the surface of the grain. It's different, so... It is appropriate to call it the 1 gate II method. Furthermore, in the peeling method of the present invention, since the sharp edge of the blade (3) is used to scrape the grain in a [-pull] manner, a large rotational force acts on the grain as a reaction to this, and as a result, the grain is cut during peeling. Vigorous agitation occurs in the grains, and the grains are peeled evenly. Such a stirring action is unique and occurs only when using the scraping method of the present invention; in the case of conventional grinding methods, the rotational force exerted on the grains is small, so the intense stirring action of the present invention is not possible. It doesn't happen. In addition, since the peeling method of the present invention uses the blade (1) to scrape off the surface of the grain, it is possible to efficiently peel the grain regardless of the conditions under which the grain is milled. For example, in the case of rice milling. There is no decrease in efficiency during the initial stage of milling from brown rice,
In addition, the milling accuracy can be increased freely, and it can be used for polishing sake barley Yonekawa, and can also be used for unhulling of grained and milled rice, as well as for a wide range of purposes such as wheat polishing. It is possible.

1) will be installed. The whitening outer cylinder (4) is a cylindrical body with a circular cross section or a polygonal shape such as hexagonal or octagonal, and is fixedly installed, and the whitening row/l/ (2) is rotated inside the whitening outer cylinder (4). Note that the polished outer cylinder (4) may be made of a perforated plate. Whitening row 7L/ (2) and whitening outer cylinder (4
) is about 5 to 20 mm, especially for rice milling.
15 mm is appropriate, but this gap size is determined as appropriate depending on the type, size, material, etc. of the milled grains. Polished outer cylinder (
The conditions of the inner surface of 4) are free, and there is no need to provide any protrusions, and metal resistance pieces (6) or blades similar to those on the roll surface may be attached.

Further, it is also possible to use various types of blades, such as one having a plurality of edges on one blade, and one having a partial edge missing part in a part of the blade in the longitudinal direction.

Efficient peeling is possible regardless of the tilt. In addition, since a vigorous stirring action is generated on the grain at the same time as the peeling action, the surface of the grain can be peeled evenly and uniformly. Furthermore, since the blade body is made of ceramic, there is extremely little wear and tear on the blade edge, allowing stable work to be carried out over a long period of time.
