。BACKGROUND TECHNOLOGY - The polishing section of a friction-type rice polishing machine has a structure in which a polishing roll having protrusions is rotated on the inner surface of an outer cylinder made of a perforated plate. Furthermore, in order to improve woodworking in the milling section, a grain feeding section is provided in the front stage of the milling section, and a pressure plate is attached to the outlet of the milling section. The structure of the grain feeding section is generally such that a grain feeding spiral is provided coaxially with the milling roll. Therefore, the supplied rice grains are forced into the grain feeding section and sent to the milling section.
In the whitening section, whitening action is applied under a predetermined milling pressure.

玄米中に穀蛾などが繁殖し、その分泌物で米粒が結着し
ているような場合である。この場合には米粒が結着して
いる為、送穀螺線による送りが充分に米粒に作用せず、
送りが不安定になるのである。In conventional friction-type rice milling machines, brown rice is directly supplied from a hopper to a grain feeding section, and from there, it is pumped to a milling section. However, in the method of directly feeding brown rice to the grain feeding section, grain feeding may be disrupted or grain feeding may become impossible, making stable rice milling operations impossible. There are various causes for this, for example:
This is a case where grain moths breed in brown rice and the rice grains are bound together by their secretions. In this case, since the rice grains are stuck together, the feeding by the grain feeding spiral does not affect the rice grains sufficiently.
This makes the feed unstable.
本発明はこのような欠点を解消して、送穀部での送りの
安定化を図り、精米作業をＪ・うなく行えるようにした
精米機を提供せんとするものである。It is an object of the present invention to provide a rice milling machine that eliminates these drawbacks, stabilizes the grain feeding in the grain feeding section, and enables rice milling operations to be carried out easily.

ていることにある。The technical means of the rice milling machine of the present invention includes a friction-type milling section, a grain feeding section connected to the front stage of the milling section, and a pre-processing section installed at the front stage of the grain feeding section, The pre-treatment section uses a grinding method to apply a light polishing to the surface of the rice grains.

げられる。In the pre-processing section, a light grinding process is applied to the surface (bran layer) of brown rice that is difficult to see with the naked eye. As a result, the bonds on the rice grains are loosened and adhered to the surface of the rice grains.
The secretions of grain moths, various deposits, and oils and fats from the rice grains are removed along with a very small amount of bran. The rice grains that have been pretreated in this way are then sent to the grain feeding section. In the grain feeding section, feeding is applied by the rotation of the grain feeding spiral, but since the rice grains have been pretreated, they are easily affected by the grain feeding action of the spiral, and the rice grains are reliably sent to the milling section. . In the milling section, milling is applied to the rice grains using a friction method to produce polished rice.

転によって精白部（６）の方へ圧送される。In the rice milling machine shown below, when brown rice is co-fed from the hopper (1), the brown rice first enters the pretreatment section (2).
It is subjected to grinding by a grinding roll (3). The accuracy of grinding in this grinding process is extremely low, and the surface of the bran layer of the rice grains is only lightly ground. The rice grains that have been pretreated by grinding enter the grain feeding section (4) and are forcedly fed toward the milling section (6) by the rotation of the grain feeding row/I/ (5).

It is not necessary to provide an integral continuous dumping system, and the pre-processing section (2) is connected to the hopper (1
) may be provided separately at another location, such as at the lower end. Pretreatment is necessary only for brown rice, so for example, in the case of a multi-stage rice mill, the first
It is sufficient to provide a pre-processing section only in the stage polishing device.

による搗精を行う際の搗精効率が良くなる利点がある。In the rice milling machine of this invention, the pre-processing section is provided before the grain feeding section, so brown rice is first subjected to grinding and polishing, which loosens the binding of the rice grains and removes any adhesion on the surface of the rice grains. The grains, oil and fat are removed along with a small amount of bran, and the rice grains become highly fluid and are sent to the grain feeding section. Therefore, in the grain feeding section, the rice grains are reliably fed by the rotation of the grain feeding spiral, the grain feeding is stable, and rice can be polished evenly. In addition, the bran removed from the surface of the rice grains in the pre-processing section moves together with the rice grains to the grain feeding section, so the presence of this bran contributes to the stability of grain feeding in the grain feeding section, creating the so-called spiral. Prevent accidents caused by dirt. Furthermore, in the present invention, since light grinding is applied to the rice grains in the pre-treatment section, there is an advantage that the milling efficiency is improved when milling is performed by friction in the milling section.
