この考案は一回通し精米機の送穀ロール室の改
良に関するものである。[Detailed description of the invention] This invention relates to an improvement of the grain feeding roll chamber of a single-pass rice mill.
従来の一回通し精米機に於いては、精白ロール
５（第１図）の回転部分で玄米に強力な精白圧力

金網６に集中圧力が作用し、米の固着による運転
不能、砕米の多発、精白ロール５、金網６の局部
的摩耗等の欠点が発生する。 In the conventional single-pass rice mill, strong polishing pressure is applied to the brown rice by the rotating part of the polishing roll 5 (FIG. 1), and the rice is polished while removing bran from the outer wire gauze 6. Therefore, concentrated pressure acts on the grain feeding side end of the milling roll 5 and its outer peripheral wire mesh 6, resulting in disadvantages such as inability to operate due to rice sticking, frequent breakage of rice, and local wear of the milling roll 5 and wire mesh 6. .
この考案は上記の欠点の解決を計るもので、一
回通し精米機の精白ロール室の玄米の受ける圧力
を送穀ロール室に分散し、精白圧力の平均化を計
ることを目的とする。 This invention aims to solve the above-mentioned drawbacks, and aims to distribute the pressure exerted on brown rice in the milling roll chamber of a single-pass rice milling machine to the grain feeding roll chamber, and to average out the milling pressure.
この考案は、送穀ロール室Ａと精白ロール室Ｂ
とを連結した装置に於て、送穀ロール室Ａの送穀
ロール１の外周に円筒２を設け、該円筒２の送穀
吐出口側に、円筒の内径D1より若干小さい内径
Ｄの絞り部４を設け、該絞り部４に接続する円筒

ある。 This idea consists of grain feeding roll room A and milling roll room B.
In this device, a cylinder 2 is provided on the outer periphery of the grain feeding roll 1 in the grain feeding roll chamber A, and a throttle having an inner diameter D slightly smaller than the inner diameter D 1 of the cylinder is provided on the grain feeding outlet side of the cylinder 2. A large number of resistance grooves 3 in the axial direction are provided on the inner periphery of the cylinder 2 connected to the constriction part 4, and the length L of the resistance grooves 3 is the length L 1 of the inner diameter D 1 of the cylinder 2.
This relates to a one-time rice milling machine that has a rice milling capacity of 1/2 or less.
この考案の実施例を図面により説明する。 An embodiment of this invention will be explained with reference to the drawings.
送穀ロール室Ａに連結して精白ロール室Ｂを設
け、送穀ロール室Ａに送穀ロール１を、精白ロー
ル室Ｂに精白ロール５を連結して設け、送穀ロー
ル１の外周に円筒２を設け、その円筒２の送穀吐
出口側に、円筒２の内径D1より３〜６mm小さい
内径Ｄの絞り部４を設け、絞り部４の長さｌを５
〜10mmとする。 A whitening roll room B is connected to the grain feeding roll room A, a grain feeding roll 1 is connected to the grain feeding roll room A, a whitening roll 5 is connected to the whitening roll room B, and a cylindrical grain feeding roll 1 is connected to the grain feeding roll room A. 2, and a constricted part 4 with an inner diameter D smaller than the inner diameter D1 of the cylinder 2 by 3 to 6 mm is provided on the grain feeding and discharge port side of the cylinder 2, and the length l of the constricted part 4 is 5 mm.
~10mm.
絞り部４があると送穀ロール室Ａ内にて玄米が
滑らかに流れぬため第１段階の精白圧力が加えら
れる。この際、円筒２の内面が滑らかな場合は、
第１段階の精白圧力が弱い。 If there is a constriction part 4, the brown rice will not flow smoothly in the grain feed roll chamber A, so the first stage of polishing pressure is applied. At this time, if the inner surface of cylinder 2 is smooth,
The whitening pressure in the first stage is weak.
そこで円筒２の内周面全長Ｌに軸線方向の抵抗
溝３を設けると、送穀ロール室Ａの精白圧力は著
しく増強され、玄米の外周滑りが防止されるので
送穀性能の低下も防止される。しかし抵抗溝３の
形状をいくら浅くしても円筒内周面全長L1に抵
抗溝を設けると、玄米に加わる精白圧力が強くな
り過ぎ、砕米発生率が増加し、軟質米の場合には
送穀ロール室Ａ内で白米化され固着現象が起る恐
れもある。 Therefore, if an axial resistance groove 3 is provided on the entire length L of the inner peripheral surface of the cylinder 2, the polishing pressure in the grain feeding roll chamber A will be significantly increased, and the sliding of the brown rice on the outer periphery will be prevented, thereby preventing a decrease in grain feeding performance. Ru. However, no matter how shallow the shape of the resistance groove 3 is, if the resistance groove is provided over the entire length L1 of the inner peripheral surface of the cylinder, the polishing pressure applied to the brown rice will become too strong, the incidence of broken rice will increase, and in the case of soft rice, the There is also a risk that the rice will become polished in the grain roll room A and a sticking phenomenon may occur.
抵抗溝３の長さＬを円筒２の内径D1の部分の
長さL1の1/2以下にすると、抵抗溝３の形状を任
意に強くしても砕米の発生率は少く、精白力も適
宜の強さとなり、かつ送穀能力も減じない。即ち
送穀ロール室Ａでの第１段の精白が理想的に行な
われ、精白ロール室Ｂで精白ロール５と金網６と
により第２段階の精白と除糠研米が行なわれるこ
ととなる。 If the length L of the resistance groove 3 is set to 1/2 or less of the length L 1 of the inner diameter D 1 of the cylinder 2, even if the shape of the resistance groove 3 is made arbitrarily strong, the incidence of broken rice will be small and the polishing power will be reduced. It has appropriate strength and does not reduce grain feeding ability. That is, the first stage of milling is ideally carried out in the grain feeding roll room A, and the second stage of milling and bran removal is carried out in the milling roll room B using the milling rolls 5 and the wire mesh 6.
前記の如く絞り部を有し、特定長さの抵抗溝を
有する円筒２を用いることにより、一回通し精米
機の精白作用が第一、第二段階に適当に分散さ
れ、それだけ精白ロール５、金網６えの集中圧力
も分散される故、局部摩耗が防止でき、かつ精白
ロール室Ｂ内での白米固着現象と砕米発生とが防
止できる。 As described above, by using the cylinder 2 having a constriction part and a resistance groove of a specific length, the polishing action of the single-pass rice milling machine is appropriately distributed to the first and second stages, and the polishing roll 5, Since the concentrated pressure on the wire mesh 6 is also dispersed, local abrasion can be prevented, and the phenomenon of sticking of white rice and generation of broken rice in the whitening roll chamber B can be prevented.
